    Appellees.
    OPINION
    In this permissive appeal we are asked to construe a 1927 mineral deed. The 1927 deed is
    only seven paragraphs long, and no party claims it is ambiguous. But, the parties have widely
    different interpretations concerning what interests the deed conveyed and the size of those
    interests. The Appellants are the successors in interest to Lynn Eddins, the original Grantor of the
    deed, and Appellees are successors in interest to John Borden, the original Grantee.            On
    cross-motions for partial summary judgment, the trial court determined that Appellees, the Borden
    Successors, were entitled to a 1/2 floating royalty interest in any production on the land described
    in the deed. We affirm.
    BACKGROUND
    Lynn Eddins owned thousands of acres of land in Reeves County. In December 1925,
    Eddins assigned John Ross the right to drill and produce oil and gas on 3,840 acres of Eddins’
    property (the “Ross Lease”). Under the Ross Lease, Eddins retained a 1/8 royalty interest in the
    production (a “one-eighth part of all oil produced and saved from said leased premises”). The
    Ross Lease was for a term of five years, or as long thereafter as oil and gas was produced on the
    land.
    4
    In 1927, Eddins executed a deed to John Borden, which conveyed certain mineral interests
    to Borden as “Grantee” on portions of Eddins’ land, which were then subject to the Ross Lease.
    We set out the relevant portions of the 1927 deed, numbering the seven paragraphs for the sake of
    clarity:
    1. THAT I, LYNN EDDINS . . . do grant, sell, convey, assign and deliver unto the
    said Grantee [John Borden], an undivided one sixteenth (1/16) interest in and to all
    of the oil, gas and other minerals in and under, and that [which] may be produced
    from the following described land situated in REEVES County, Texas, to-wit:
    2. All of Sections No. Two (2), Eight (8), Ten (10), Fourteen (14), and Twenty Two
    (22) Block C-1, Public School lands, and containing 3200 acres, more or less,
    3. Together with the right of ingress and egress at all times for the purpose of mining,
    drilling, and exploring said land for oil, gas and other minerals, and removing the
    same therefrom.
    4. Be it expressly understood between the parties that the vendor is the owner of all of
    the royalty and that the grantee is purchasing one half (1/2) of the royalty [] one half
    (1/2) of the minerals, produced in and from wells or other operations situated on the
    specific tract of land described in this instrument.
    5. [S]aid land being now under an oil and gas lease executed in favor of John Ross, it
    is understood and agreed that this sale is made subject to the terms of said lease, but
    covers and includes one half (1/2) of all of the oil royalty, and gas rental or royalty
    due and to be paid under the terms of said lease.
    6. It is understood and agreed that none of the money rentals which may be paid to
    extend the term within which a well may be begun under the terms of said lease is
    to be paid to the said Grantee and in [the] event that the above described lease for
    any reason becomes cancelled or forfeited, then and in that event an undivided one
    sixteenth (1/16) of the lease interest and all future rentals on said land for oil, gas
    and other mineral privileges shall be owned by said Grantee, he owning one
    sixteenth of all oil, gas and other minerals in and under said lands, together with no
    interest in all future rents.
    7. TO HAVE AND TO HOLD THE ABOVE DESCRIBED PROPERTY, together
    with all and singular the rights and appurtenances thereto in anywise belonging
    unto the said Grantee herein, and his heirs and assigns forever…. And it shall
    never be necessary for said grantee or his assigns to join in the execution of any
    future leases made on said lands.
    5
    Borden thereafter transferred his interest in the 1927 deed to a corporation that he owned,
    Ventures, Inc., which in turn transferred its interest to an unrelated third-party, Cecil Cothrun, in
    1948.1 Since that time, the successors to both Eddins and Borden/Cothrun have made numerous
    conveyances of their respective interests in the deed.
    Although it is unclear exactly when the Ross Lease expired, the parties agree that the Ross
    Lease expired at some point long ago, and that the successors to Eddins’ interests (the Eddins
    Successors) entered into a lease with Patriot Resources, Inc., the current operator of numerous oil
    and gas leases on the mineral properties that are the subject of the 1927 deed (the “Patriot Leases”).
    The royalty interest under the Patriot Leases is currently 25 percent for most of the leases, and 24
    percent for others. For purposes of clarity, we will simply refer to this as a 1/4 royalty interest.
    In 2013, Patriot filed an interpleader action in the trial court, naming 80 defendants, 30 of
    whom were Eddins Successors, and 50 of whom were Borden Successors (successors in interest to
    Borden and Cothrun). Patriot asserted that the 1927 deed was ambiguous, and that it was unable
    to determine the interests owned by the Borden Successors under the terms of the deed. In
    particular, Patriot asserted that because there were conflicting fractions in the deed, it was not
    certain whether the Borden Successors were entitled to receive: (1) 1/16 of the total production in
    any lease on the property regardless of the size of the royalty interest set by the terms of the lease
    1
    In 1948, Borden, Cothrun, and Eddins entered into two separate agreements in which they purportedly sought to
    clarify their respective intentions. A document entitled Royalty Agreement (signed by the original parties, Eddins
    and Borden, together with Borden’s first successor, his own corporation, Ventures, Inc.) provided that the parties
    intended for Eddins to convey a “full, free one-sixteenth 1/16th ROYALTY INTEREST” to Borden, while another
    document entitled Supplementary Agreement (signed by Borden and Ventures Inc., and their successor in interest,
    Cecil Cothrun) provided that Cothrun was receiving a 1/2 floating royalty interest. In the Supplementary Agreement,
    Cothrun expressly stated that he was only claiming a 1/2 royalty interest in the estate rather than a 1/2 mineral interest.
    However, as the Borden Successors point out, the trial court did not base its decision on the 1948 agreements, and
    instead based its decision solely on its interpretation of the 1927 deed. Therefore, the issue of how the 1948
    agreements may have affected the parties’ interests is not properly before us in this limited appeal.
    6
    (i.e., a 1/16 fractional royalty interest); or (2) 1/2 of the royalty interest set by the terms of any lease
    on the property (i.e., a floating royalty interest), which, under the current Patriot Leases would
    have given the Borden Successors a 1/2 interest in the 1/4 royalty under those leases, or what
    would effectively amount to a 1/8 interest in the total production. Ultimately, the trial court
    allowed Patriot to deposit $306,887.38 into the registry of the court, and dismissed Patriot from the
    lawsuit, without prejudice.
    Both the Eddins Successors and the Borden Successors filed various cross-claims seeking
    declaratory relief, asking the court to resolve the ownership interest in their favor. Subsequently,
    both the Borden Successors and the Eddins Successors filed cross-motions for partial summary
    judgment, seeking the trial court’s ruling on how to interpret the 1927 deed.
    Before focusing on the arguments made by the parties and the decision made by the trial
    court, we believe it would be beneficial to provide background on the nature of the mineral
    interests at stake in this case, and an overview of the manner in which courts have historically
    construed mineral deeds of this nature.
    The Nature of Mineral Interests
    We start with a basic overview of the nature of mineral interests in general. An instrument
    conveying land in fee simple transfers both the surface estate and the mineral estate to the grantee,
    unless the instrument contains a reservation or expresses a contrary intention. Hysaw v. Dawkins,
    
    483 S.W.3d 1
    , 9 (Tex. 2016). The mineral estate is composed of five severable rights, which may
    be conveyed in total or separately to a third party: (1) the right to develop (the right to explore and
    drill for minerals); (2) the right to lease, also known as the executive interest (the right to lease to
    an operator who will then explore and drill on the property); (3) the right to receive bonus
    7
    payments (payments typically given on the front end of a lease at the time of signing); (4) the right
    to receive royalty payments (payments for a certain percentage of any production on the land); and
    (5) the right to receive delay rentals (payments made to the royalty interest owner when there is a
    delay in the agreed-upon time in which production is to begin). 
    Id. The holder
    of the executive or lease interest enjoys the exclusive right to make mineral
    leases to an operator who will have the sole right to explore and drill for minerals on the land. 
    Id. In Texas,
    a typical oil and gas lease conveys the mineral estate as a fee simple determinable estate
    to the lessee, with the possibility of reverter to the lessor as a future interest, and typically includes
    provisions for the payment of bonus payments and delay rentals to the lessor, as well as for the
    payment of a royalty to the lessor during the term of the lease. The royalty payments are typically
    expressed as fractions of an interest in the total production. 
    Id. (citing Luckel
    v. White, 
    819 S.W.2d 459
    , 464 (Tex. 1991)). The lessor may convey any interests he retains to a third party,
    including the royalty interest, either in its entirety or as a fraction of the interest. Id; see also
    Garza v. Prolithic Energy Co., L.P., 
    195 S.W.3d 137
    , 142-43 (Tex.App. – San Antonio 2006, pet.
    denied).
    When a mineral estate is conveyed, the grantor may reserve any interest or fraction of an
    interest in the estate that he wishes to retain; however, the mineral interest conveyed, even if it is
    “shorn of the executive right and the right to receive delay rentals remains an interest in the
    mineral fee.” 
    Garza, 195 S.W.3d at 142
    . In other words, when a mineral interest is conveyed,
    even if the grantor reserves all but the royalty interest, it is still considered a mineral interest, even
    though the only practical effect of the conveyance is to give a royalty interest in the operator’s
    production. 
    Id. 8 The
    lease holder may decide to convey both an “undivided portion of the mineral estate and
    a separate royalty interest” in the same land, either in the same or in a separate instrument.
    
    Hysaw, 483 S.W.3d at 9
    . These two estates may be of equal size, or the lease holder may convey
    two interests of a different size. In other words, the lease holder may convey a royalty interest
    that is “larger or smaller than the interest conveyed in the minerals in place.” 
    Id. The Differing
    Royalty Interests
    A conveyance of a royalty interest, standing alone, is non-possessory in nature. A party
    possessing only the royalty interest with none of the other mineral interests (e.g., the right to lease,
    or to receive delay rentals or bonus payments), is referred to as a non-participating royalty-interest
    holder. 
    Id. Royalty interests
    may be conveyed or reserved as a fixed fraction of total production,
    (also known as a fractional royalty interest) or as a fraction of the total royalty interest (also known
    as a “fraction of royalty interest” or, as we shall refer to it, a “floating” royalty interest). 
    Id. The floating
    royalty interest varies in accordance with the size of the landowner’s royalty. Thus, if a
    party receives a 1/2 floating royalty interest, the interest will be calculated by multiplying the
    fraction in the royalty reservation by the royalty provided in the lease. 
    Id. For example,
    if a
    lease calls for a 1/8 royalty interest, such as the Ross Lease did, the holder of the 1/2 floating
    royalty would be entitled to 1/16 of the total production. However, if a new lease is later
    negotiated calling for a 1/4 royalty, such as the Patriot Leases, the 1/2 floating royalty owner’s
    interest essentially expands, and the royalty owner would be entitled to 1/8 of the total production.
    On the other hand, if the royalty is expressed as a fixed fraction, the grantee is always
    entitled to only that fraction of production, regardless of the royalty set forth in the lease. For
    example, a conveyance of a fixed fraction of 1/16 gives the grantee 1/16 of the production, which
    9
    remains constant, regardless of whether an operator’s lease calls for the payment of a 1/8 or 1/4
    royalty interest.
    The Double-Fraction Problem and the Legacy of the 1/8th Royalty
    As the Supreme Court recognized in Hysaw, the interpretation of a deed that uses a single
    fraction throughout to express the interests conveyed is a relatively simple matter. 
    Id. (citing Garrett
    v. Dils Co., 
    299 S.W.2d 904
    , 906 (Tex. 1957)). However, many older deeds, such as the
    1927 deed under consideration, often contained seemingly conflicting fractions either in the same
    paragraph or in different paragraphs, as well as double fractions (such as 1/2 of 1/8). Because of
    this, over the years, Texas courts have been faced with recurring interpretive challenges in
    construing those deeds. 
    Id. (citing Garrett
    , 299 S.W.2d at 906, and Concord Oil Co. v. Pennzoil,
    
    966 S.W.2d 451
    , 452, 454 (Tex. 1998)). When a court is presented with conflicting or double
    fractions in a deed, the court’s task is always to “discern the intent of the parties from the four
    corners of the document,” and the court must “consider the entire instrument to determine what has
    been conveyed.” Concord Oil 
    Co., 966 S.W.2d at 457
    .
    In Hysaw, the Court explained that one of the reasons many older deeds, including those
    dating back to the 1920’s, contained conflicting or double fractions was because when the deeds
    were drafted, the standard royalty in virtually all lease agreements was 1/8. Therefore, many
    older deeds expressed royalty interests in fractions of 1/8. Because many royalty interest holders
    believed their royalty interest would always be 1/8 and that the interest would never vary from that
    amount, a grantor would often use the “near ubiquitous” 1/8 fraction as a shorthand to express the
    royalty interest he was conveying, or in other words, as a “proxy” for his entire royalty interest.
    
    Hysaw, 483 S.W.3d at 9
    -11. For example, the grantor might use the double fraction 1/2 of 1/8, or
    10
    alternatively the single fraction 1/16, to express that he was actually giving the grantee 1/2 of his
    entire royalty interest. Under that interpretation, the grantee would be given a 1/2 interest, which
    would be applicable to any current and future leases, making it a floating 1/2 royalty interest. The
    Court noted that this notion has been dubbed the “legacy of the 1/8th royalty.” 
    Id. at 10.
    This possibility did not take on any significance until later years when parties began
    negotiating leases with larger royalty interests, such as the 1/4 interest included in the Patriot
    Leases. When that occurred, it became important to determine whether the grantee using a
    double fraction, or a fraction that was a multiple of 1/8, such as 1/16, intended to give the grantee a
    1/2 floating royalty interest in any royalty set forth in a lease, or whether the 1/16 was intended to
    be a fractional royalty interest that was fixed regardless of the royalty set forth in the lease. 
    Id. The Court
    in Hysaw noted that although “not inexorably so, the reality is that use of 1/8 (or
    a multiple of 1/8) in some instruments undoubtedly embodies the parties’ expectation that a future
    lease will provide the typical 1/8th landowners’ royalty with no intent to convey a fixed fraction of
    gross production.” 
    Id. Instead, the
    Court noted that there is otherwise “‘little explanation’ for
    the use of double factions [sic] to express a fixed interest absent a misunderstanding about the
    grantor’s retained ownership interest or use of 1/8 as a proxy for the customary royalty.” 
    Id. at 10-11.
    However, if the language in a deed is otherwise clear, “the possibility that the parties were
    operating under the assumption that future royalties would remain 1/8 will not alter clear and
    unambiguous language that can otherwise be harmonized.” 
    Id. at 10.
    The Estate Misconception Doctrine
    The Court in Hysaw also discussed a related issue in double-fraction cases, known as the
    “estate misconception” doctrine, which applies to the mineral estate that a landowner retains when
    11
    he leases his land to an operator, known as the possibility of reverter. 
    Hysaw, 483 S.W.3d at 10
    .
    When a landowner leases his land to an operator, it is typically through a conveyance of fee simple
    determinable with a possibility of reverter in the entire mineral estate, which does not become a
    possessory right until the lease expires. Jupiter Oil v. Snow, 
    819 S.W.2d 466
    , 468 (Tex. 1991).
    The possibility of a reverter under a lease is a separate estate, and just like any other mineral
    interest or estate, the landowner may then convey his possibility of reverter, or a fraction thereof,
    to a third party. 
    Id. (“Texas courts
    have long recognized that the owner of a mineral estate can sell
    or assign the possibility of reverter.”).
    In earlier times, many landowners labored under the misconception that when they leased
    their mineral estate to an operator, they only retained 1/8 of the minerals in place, rather than a fee
    simple determinable with the possibility of reverter in the entirety of the mineral estate (i.e., in 8/8
    of the mineral estate). 
    Hysaw, 483 S.W.3d at 10
    . Therefore, when the landowner conveyed a
    mineral interest to a third party in land that was already subject to a lease, he would often use a
    fraction of 1/8 to express what interest he intended to convey in his possibility of reverter. See 
    id. (“For example,
    a lessor who has leased the entire mineral estate, but desires to sell-one half [sic] of
    the minerals, would assume that he owned 1/8 of the minerals due to the existing lease . . . [and]
    would use the fraction 1/16, or a double fraction, 1/2 of 1/8, to convey 1/2 of what he perceived he
    owned.”). Since a landowner in reality retains a full 8/8 interest in the reverter, the application of
    the estate misconception doctrine has tremendous consequences. Under this example, if the
    grantee is only given a 1/16 mineral interest, he or she only receives 1/16 of any royalty set under
    a lease; however, if the grantee is given 1/2 of the entire mineral estate in the reverter, he owns a
    full 1/2 of the mineral interests, and would therefore be entitled to a full 1/2 of any royalty owed
    12
    under any future lease. 
    Id. Despite discussing
    these various doctrines that may be applied when interpreting mineral
    deeds containing conflicting or double fractions, the Court in Hysaw noted that there are simply no
    “bright-line” rules or “mechanically applied, mathematical approach[es],” that may be universally
    applied in interpreting deeds of this nature. Therefore, although the “estate-misconception theory
    and the historical use of 1/8 as the standard royalty may inform the meaning of fractions stated in
    multiples of 1/8 . . . these considerations are not alone dispositive[,]” and instead the focus should
    be on the parties’ intent when interpreting a deed.    
    Hysaw, 483 S.W.3d at 12-13
    .
    The Parties’ Arguments in the Trial Court
    In the trial court, the Borden Successors argued that the 1927 deed gave Borden (and
    therefore his successors) a single grant of a floating 1/2 royalty interest, meaning that they were
    entitled to 1/2 of any royalty provided for in any lease on the land, including both the now-expired
    Ross Lease and the current Patriot Leases. Therefore, under the Ross Lease, Borden and his
    successors would have been entitled to a 1/2 interest in the 1/8 royalty interest set forth in that
    lease, which would have resulted in giving them a 1/16 share of the total production. But using
    this same analysis, the Borden Successors would be entitled to a 1/2 interest in the 1/4 royalty set
    forth in the existing Patriot Leases, which would result in giving them a 1/8 share of the total
    production.
    The Eddins Successors, which broke into two main groups, the Wolf Bone Ranch Group
    (“Wolf Bone”) and the Greer Group, however, argued that the 1927 deed conveyed two separate
    and distinct estates to Borden, one temporary and one permanent. First, in agreement with the
    Borden Successors, they posited that Borden was entitled to a 1/2 royalty interest under the Ross
    13
    Lease, giving Borden and his successors a 1/16 share of the total production under that lease.
    However, the Eddins Successors argued that this was a temporary estate that expired when the
    Ross Lease expired. The Eddins Successors argued that when this temporary estate expired, a
    second estate arose, which they posited took one of two possible forms. They described the first
    possible remaining estate as a perpetual undivided 1/16 mineral interest in the lands, stripped of
    the executive rights to lease the land, which would have given the Borden Successors a 1/16
    interest in the 1/4 royalty under the Patriot Leases, resulting in a 1/64 share in the total production
    under those leases.       They described the second possible remaining estate as a fixed 1/16
    nonparticipating fixed royalty interest, which would have entitled the Borden Successors to a
    larger 1/16 share of the total production on the land under any lease regardless of the size of the
    royalty interest set forth in the lease.2
    The Trial Court’s Decision
    The trial court agreed with the Borden Successors’ position that the 1927 deed conveyed
    a 1/2 floating royalty interest to Borden, which under the 1/4 royalty interest set by the Patriot
    Leases gave the Borden Successors the right to receive a 1/8 interest in the total production under
    that lease. The trial court therefore granted the Borden Successors’ motions and denied the
    Eddins Successors’ cross-motions.
    The trial court certified the case for a permissive interlocutory appeal finding that an
    immediate appeal would materially advance the ultimate termination of the litigation. See TEX. R.
    CIV. P. 168; TEX. CIV. PRAC. & REM. CODE ANN. § 51.014(d) (West Supp. 2016); TEX. R. APP. P.
    2
    Wolf Bone made these arguments in a cross-motion for partial summary judgment in which the Greer Group joined.
    However, the Greer Group also filed its own claim for declaratory relief, seeking a declaration that the Borden
    Successors were only entitled to a 1/64 share of the total production under the Patriot Leases, as advocated in the
    second alternative in the Wolf Bone’s cross-motion for partial summary judgment. Several of the other Eddins
    Successors joined in the Greer Group’s claim for declaratory relief.
    14
    28.3. The court described the two “controlling questions of law as to which there is a substantial
    ground for difference of opinion regarding the nature and size of the oil and gas interests
    conveyed” as follows:
    1. Whether the deed conveys a single grant of a floating 1/2 of the royalty interest, as
    this Court has concluded, or, as the successors to Lynn Eddins contend, two grants
    consisting of 1/2 of the royalty interest in the land subject to an oil and gas lease at the
    time of the grant, and a fixed perpetual 1/16th mineral interest?
    2. Whether the deed conveys a single grant of a floating 1/2 of the royalty interest, as
    this Court has concluded, or, as the successors to Lynn Eddins alternatively contend,
    a fixed 1/16th royalty interest?
    This Court subsequently granted the parties the right to pursue this permissive appeal.
    DISCUSSION
    In a single issue on appeal, the Eddins Successors contend the trial court erred in its
    interpretation of the 1927 deed when it granted the Borden Successors a floating 1/2 royalty
    interest under the current lease.

    . The task of determining a grantor’s intent is
    highly case-specific, and a “[v]ariety of outcome should be expected because written instruments
    must be interpreted in light of the parties’ intent as expressed in the entire document.” 
    Id. Analysis The
    Eddins Successor groups, Wolf Bone and the Greer Group, present two different
    approaches on appeal. Although the Borden Successors’ ultimate share of total production is the
    same 1/64 under either approach, the two groups ask us to interpret the 1927 deed differently.
    Wolf Bone argues for the first alternative, stated in question one as certified by the trial court, that
    16
    the 1927 deed made two grants to Borden: (1) a temporary estate consisting of 1/2 of the royalty
    interest set forth in the Ross Lease, which terminated with the expiration of the Ross Lease; and (2)
    a second estate that arose once the Ross Lease expired consisting of a fixed perpetual 1/16 mineral
    interest. This interpretation would entitle the Borden Successors to a 1/64 share of the production
    under the Patriot Leases (i.e., 1/16 of the 1/4 royalty interest set by the leases).3
    The Greer Group, on the other hand, appears to be making an entirely new argument on
    appeal—one that is not stated in either of the trial court’s two questions—that the Borden
    Successors should be given a floating 1/16 royalty interest, that is, 1/16 of any royalty interest
    under any lease on the land, which would give the Borden Successors a 1/64 share of the total
    production under the Patriot leases (1/16 of the 1/4 royalty under the leases). We find both
    approaches to be fatally flawed.
    The Greer Group Fails to Construe the Deed as a Whole
    The Greer Group’s argument is focused solely on its interpretation of paragraph 6 in the
    deed, which the Greer Group refers to as the future lease clause. Paragraph 6 states that when the
    Ross Lease terminated, “then and in that event an undivided one sixteenth (1/16) of the lease
    interest and all future rentals on said land for oil, gas and other mineral privileges shall be owned
    by said Grantee, he owning one sixteenth of all oil, gas and other minerals in and under said lands,
    together with no interest in all future rents.” Pointing out that paragraph 6 only used the fraction
    “1/16” to explain what interest was to be conveyed to Borden upon the termination of the Ross
    Lease, the Greer Group contends was a clear indication that the parties intent was to transfer a 1/16
    interest to Borden in any future leases. The Greer Group contends that paragraph 6 is the only
    3
    Wolf Bone no longer makes the alternative argument, as stated in Question Two, that the Borden Successors should
    be given a fixed 1/16 royalty interest, which would have given the Borden Successors 1/16 of the total production
    under the Patriot Leases.
    17
    provision in the deed that we should consider in determining the size of the interest the parties
    intended to convey to Borden (and thereby the Borden successors) upon the termination of the
    Ross Lease, and that we should essentially ignore every other provision in the deed as being
    irrelevant. In particular, the Greer Group points out that Patriot’s interpleader lawsuit only asked
    the court to determine what interest it was obligated to pay to the Borden Successors under the
    Patriot’s Leases, and the Greer Group contends that only the future lease clause (paragraph 6)
    answers that question. Following this logic, the Greer Group asserts that if we were to consider
    any other provisions in the deed in determining the Borden Successors’ interest in the Patriot
    Leases, or if we were to decide what other interests or rights the Borden Successors might have
    under other provisions in the deed, this would constitute an improper “advisory opinion” in which
    we would be determining issues and interests that are not the subject of the lawsuit and therefore
    not before the Court. We disagree. The Greer Group’s approach to construction of the 1927
    deed would be in direct contravention of the Supreme Court’s directive on how to interpret mineral
    deeds.
    As explained above, the Supreme Court has repeatedly held that a grantee’s future
    interest—or any other interest—in a mineral deed can only be determined by viewing the deed in
    its entirety, and by construing each and every provision in the deed and harmonizing any apparent
    conflicts found in the deed as a whole. See, e.g., 
    Hysaw, 483 S.W.3d at 13
    ; 
    Stribling, 458 S.W.3d at 20
    ; 
    Luckel, 819 S.W.2d at 462
    ; 
    Coker, 650 S.W.2d at 393
    . Further, the Court has expressly
    warned that it is improper to consider a single clause or phrase in isolation when construing a deed,
    and that a court must instead attempt to give meaning to all provisions in the deed when possible,
    without rendering any provision meaningless.

    Corp., 94 S.W.3d at 554
    (court must presume that the parties
    to a lease intended that every clause in the lease was to have some effect).
    Moreover, none of the cases cited by the Greer Group support the proposition that a court
    should only look to a future lease clause when determining a grantee’s interest in a deed—even if,
    as in the present case, the grantee’s interest in a future lease is the only question under
    consideration by the court. In fact, in Garrett v. Dils, the Court reached an opposite 
    conclusion. 299 S.W.2d at 906
    . Although the “immediate” question before the Court centered on the amount
    of the royalty a grantee was to be paid under a lease that was not in existence when a deed was
    signed, the Court noted that this question could only be answered by determining what interest the
    grantee had in the lease that was in existence when the parties first entered into the deed, and
    looked to the entirety of the deed in “determining from the language of the deed whether it was the
    intention of the parties that the royalty was to be the same under subsequent leases.” 
    Id. Similarly, in
    virtually every other case cited by the Greer Group, the courts determined the size and
    nature of a grantee’s interest in a future lease by looking not only to a deed’s future lease clause,
    but by considering and harmonizing every other provision in the deed in order to determine exactly
    what the grantor intended to convey to the grantee, both in terms of existing as well as future
    leases.4 See, e.g., Concord Oil 
    Co., 966 S.W.2d at 458

    The Greer Group correctly point outs that in determining the parties’ interest under an existing lease, the Court in
    Richardson v. Hart, 
    185 S.W.2d 563
    , 565 (Tex. 1945), did not also purport to determine what interest, if any, the
    parties might have under future leases, as that issue had not been presented for its consideration. However, the Court
    did look to virtually every other paragraph in the deed in determining that interest. 
    Id. at 564-65.
    Further, that the
    Supreme Court, in one isolated case, may have declined to consider one of the provisions in a deed in determining a
    grantee’s interest, cannot serve as basis for the Greer Group’s argument that a court should construe deed provisions in
    in isolation, because virtually every other Supreme Court opinion, including the Court’s most recent opinion in
    Hysaw, have all clearly and unequivocally adhered to the doctrine that in determining the grantor’s intent, every
    provision in a deed must be considered and that provisions must not be construed in isolation. See, e.g., Hysaw, 483
    19
    future lease, the Court reviewed the parties’ deed as a whole to determine the nature of the interests
    the grantor intended to convey in both existing and future leases); 
    Luckel, 819 S.W.2d at 462
    (court considered the “actual intent of the parties as expressed in the instrument as a whole” in
    determining the grantee’s interests in both existing and future leases); Jupiter 
    Oil, 819 S.W.2d at 468-69
    (in determining the grantee’s interest in a future lease, the court did not limit its
    consideration to the deed’s future lease clause, and instead looked to all provisions in the deed,
    harmonizing seemingly conflicting provisions, in an attempt to ascertain the grantor’s intent).
    As such, we must look to all of the provisions in the 1927 deed and attempt to harmonize
    those provisions in determining exactly what Eddins intended to convey to Borden in the 1927
    deed, and this analysis must include a discussion of Borden’s interest in both the existing Ross
    Lease and any future leases, as well as the general nature and scope of any other interests conveyed
    to Borden in the deed.5
    The Deed Conveyed More Than a Royalty Interest
    Both Wolf Bone and the Borden Successors appear to agree that the 1927 deed conveyed to
    Borden a 1/2 royalty interest in the then-existing Ross Lease. However, that is where their
    agreement stops. The Borden Successors argue that no mineral estate was conveyed in the deed,
    and that instead, the only conveyance under the deed was a 1/2 floating royalty interest, which was
    applicable to both the existing lease (i.e., the Ross Lease) and all future leases (i.e., the Patriot
    Leases). Wolf Bone, on the other hand, contends, in essence, that two estates were conveyed to
    S.W.3d at 13.
    5
    We also note, as discussed below, that paragraph 6 is replete with language indicating that Borden was to be left with
    a 1/16 mineral interest in the land upon the expiration of the Ross Lease, undercutting the Greer Group’s argument that
    paragraph 6 left Borden with only a 1/16 royalty interest.
    20
    Borden, one of which was a temporary 1/2 royalty interest under the Ross Lease, which ended with
    the termination of that lease, and a separate 1/16 mineral interest that arose upon the expiration of
    the Ross Lease.
    We consider the Borden Successors’ argument first. The Borden Successors contend that
    no mineral interest was conveyed by the 1927 deed, and that the only interest conveyed was a
    royalty interest.6 They point out that paragraphs 4 and 5 of the deed both contain references to a
    royalty interest. In particular, they note that paragraph 5 refers to the 1/2 royalty interest that
    Borden was given under the Ross Lease, and that paragraph 4 states, among other things, that
    Borden was purchasing 1/2 of Eddins’ “royalty” interest. The Borden Successors’ argument,
    however, overlooks that in paragraph 4, the deed also indicates that Borden was purchasing 1/2 of
    the “minerals, produced in and from wells or other operations situated on the specific tract of land
    described in this instrument[,]” which the Supreme Court has recognized is the clear language of a
    mineral interest conveyance. See, e.g., Concord Oil 
    Co., 966 S.W.2d at 453
    , 459 (holding that
    language in a deed conveying an “interest in and to all of the . . . minerals in and under, and that
    may be produced,” is clearly indicative of a mineral interest); French v. Chevron U.S.A., Inc., 
    896 S.W.2d 795
    , 796, 798 (Tex. 1995) (language conveying an “interest in and to all of the oil, gas and
    other minerals, in, under and that may be produced from the following described lands” was
    clearly that of a mineral interest); 
    Richardson, 185 S.W.2d at 564-65
    (construing similar language
    to connote a mineral interest); see also 
    Garza, 195 S.W.3d at 142
    -43 (the phrase “in and under”
    refers to a mineral interest) (citing Laura H. Burney, Interpreting Mineral and Royalty Deeds: The
    6
    At various times in their brief, the Borden Successors indicate that, although they are disclaiming any right to a
    mineral interest, they have no objection to the court also finding that a mineral interest was conveyed by the deed, in
    addition to a royalty interest, but only if the court were to find it to be a 1/2 mineral interest and not the 1/16 interest
    argued for by the Eddins Successors.
    21
    Legacy of the One–Eighth Royalty and Other Stories, 33 St. Mary's L.J. 1, 30–31 (2001)).
    Similarly, the Borden Successors’ argument would have us focus on only those two
    references to a royalty interest in paragraphs 4 and 5 and have us overlook virtually every other
    provision in the deed, which is contrary to Supreme Court precedent. In particular, the Borden
    Successors would have us overlook paragraph 1, which purports to grant to Borden an interest “in
    and to all of the oil, gas and other minerals in and under, and that may be produced” on the land,
    which again, is classic language of a mineral interest. Similarly, the Borden Successors would
    have us overlook paragraph 3, which purports to give Borden “the right of ingress and egress at all
    times for the purpose of mining, drilling, and exploring said land for oil, gas and other minerals,
    and removing the same therefrom.” As the Supreme Court has recognized, a conveyance
    purporting to transfer to a grantee the right of ingress and egress for the purpose of mining, drilling
    and exploring is by definition a mineral interest rather than a royalty interest. In particular, the
    Court has noted that such language is possessory in nature, and that royalty interests are by
    definition non-possessory in nature, and that therefore, a grantee holding only a royalty interest
    would not be given that right. See, e.g., Concord Oil 
    Co., 966 S.W.2d at 459
    (rights of ingress
    and egress and the right to develop the mineral estate is “classic language used in granting an
    interest in minerals”); see also Prairie Producing Co. v. Schlachter, 
    786 S.W.2d 409
    , 412 (Tex.
    App. – Texarkana 1990, writ denied) (a royalty owner has no right to explore and drill).
    The Borden Successors nevertheless argue that we should essentially overlook this
    language denoting the conveyance of a mineral interest, in favor of the two references made in the
    deed to the conveyance of a royalty interest. However, the cases cited by the Borden Successors
    for this proposition belie their argument, and suggest that we may not simply overlook the
    22
    language in the deed indicating that a mineral interest was being conveyed, and that we must
    instead construe the deed as a whole in order to give effect to the grantor’s intent. See, e.g.,
    Watkins v. Slaughter, 
    183 S.W.2d 474
    , 475, 477 (Tex.Civ.App. – Amarillo 1944), aff’d, 
    144 Tex. 179
    , 
    189 S.W.2d 699
    (1945) (deed was construed to reserve a 1/16 royalty interest, where the deed
    initially stated it was conveying an undivided fifteen-sixteenths interest in “all the oil, gas and
    other minerals in and under and that may be produced from said land and the grantor retains title to
    a 1/16 interest in and to all of the oil, gas and other minerals in and under and that may be produced
    from said land,” but later expressly referred to the grantor’s reserved interest as being a royalty);
    Temple-Inland Forest Prods. Corp. v. Henderson Family P’ship, Ltd., 
    958 S.W.2d 183
    , 185-86
    (Tex. 1997) (similar deed was construed to reserve a 1/16 royalty interest, where the deed initially
    conveyed an undivided fifteen-sixteenths interest in “all of the oil, gas and other minerals . . . that
    may be produced,” but later expressly referred to the grantor’s reserved interest as being a royalty).
    Unlike the cases cited by the Borden Successors, in the present case, the 1927 deed did not
    make a mere passing reference to a mineral interest, and instead, the deed is replete with language
    indicating that Eddins intended to convey a mineral interest—language that is found in almost
    every provision in the deed. Further, unlike the above cases, the 1927 deed case did not contain
    any subsequent paragraphs clarifying that the interest to be conveyed was only a royalty interest.
    Moreover, in addition to the repeated provisions in the deed using the language of a
    mineral interest, we find it significant that both paragraphs 6 and 7 state that Eddins was reserving
    certain mineral interests in the land, when he reserved the right to receive “future rentals” under the
    Ross Lease, and when he stated that Borden was not required to join in the execution of any future
    leases. Because a royalty interest holder does not have the right to receive any such rentals or the
    23
    right to execute leases, there would be no reason for Eddins to reserve those mineral rights if in fact
    he only intended to convey to Borden a royalty interest alone. See, e.g., 
    Garza, 195 S.W.3d at 142
    (the court noted that the reservation in a deed of the various attributes of a severed mineral
    estate would have been “redundant” if only a royalty interest was conveyed); see also 
    French, 896 S.W.2d at 798
    (a conveyance that reserved various mineral interests, although at times referred to
    as a royalty interest, would have been redundant and served no purpose if the interests in minerals
    being conveyed was royalty interest); see also Bank One, Texas, Nat'l Assoc. v. Alexander, 
    910 S.W.2d 530
    , 535 (Tex.App. – Austin 1995, writ denied) (finding deed reserved a mineral interest
    because express conveyance of all other mineral interests owned by the grantor would be
    redundant if deed intended to reserve only a royalty interest).
    Further, the only two sentences in the deed that refer to a royalty interest are easily
    reconciled with the remaining passages in the deed referring to the conveyance of a mineral
    interest. Paragraph 5 states that the conveyance is being made subject to the Ross Lease, and that
    Borden is being given a 1/2 royalty interest in that lease. We construe that to mean that Eddins
    intended to express that the mineral interest being conveyed included a concomitant royalty
    interest in the Ross Lease, a position entirely consistent with the conveyance of a mineral interest.
    See, e.g., Concord Oil, 
    Co., 966 S.W.2d at 459
    (although the granting clause in a deed appeared to
    convey only a 1/12 royalty interest to grantee, the deed as a whole was construed to give the
    grantee a 1/12 mineral interest, which included the 1/12 royalty interest applicable to all leases on
    the land). Further, paragraph 4, while less clear, states that Eddins is the “owner of all of the
    royalty and that [Borden] is purchasing one-half (1/2) of the royalty [] one half (1/2) of the
    minerals, produced in and from wells or other operations situated on the specific tract of land
    24
    described in this instrument.” While this provision suffers from a lack of punctuation, in light of
    the other language used in the deed, we construe it to mean that Eddins intended to convey to
    Borden a mineral interest, which included a corresponding royalty interest.
    In short, if we were to agree with the Borden Successors that only a royalty interest was
    conveyed, we would have to negate all but the two sentences in the deed, and ignore virtually
    every other provision in the deed referring to the conveyance as being that of a mineral interest.
    Instead, a construction of the deed that it conveyed both a mineral interest and a royalty interest is
    the only interpretation that satisfactorily harmonizes and explains each and every provision in the
    deed, as required by Supreme Court precedent.
    We recognize that the Borden Successors may undoubtedly waive their right to assert an
    interest to any mineral rights under the deed, and may instead ask us to only enter a judgment
    awarding them any corresponding royalty interest to which they might be entitled under the deed,
    or in other words, the royalty interest to which they would be entitled as mineral interest owners.
    However, this does not mean that we can, or should, ignore the repeated references in the deed to
    the conveyance of a mineral interest to Borden. To the contrary, as explained below, our
    determination that a mineral interest was conveyed by the deed, together with the size of that
    interest, will determine the size and type of royalty interest the Borden Successors have under the
    deed, as the two concepts are inextricably intertwined.
    The 1927 Deed Conveyed a 1/2 Mineral Estate to Borden
    In order to determine the nature and size of the mineral interest that Eddins conveyed to
    Borden in the 1927 deed, it is first important to understand exactly what interest Eddins retained in
    the mineral estate on his land after he executed the Ross Lease, and therefore what interest he was
    25
    able to convey to Borden after the execution of that lease. As explained above, prior to executing
    the Ross Lease, Eddins owned 100 percent of the mineral estate on his land, but upon executing the
    Ross Lease, Eddins conveyed to Ross the right to develop (i.e., the right to explore and drill for
    minerals on the land), but reserved the following interests: (1) a 1/8 royalty interest in that lease,
    entitling him to 1/8 of the production on the land; (2) the remainder of the five mineral estate
    interests not conveyed to Ross (i.e., the executive right to execute leases, and the rights to receive
    bonus payments and delay rentals); and (3) the possibility of reverter in the entire mineral estate
    upon the expiration of the Ross Lease. See 
    Hysaw, 483 S.W.3d at 10
    (the possibility of reverter
    includes the entire mineral estate); Jupiter 
    Oil, 819 S.W.2d at 468
    .
    Wolf Bone contends that Eddins conveyed two separate estates to Borden of unequal size,
    type, and duration. In particular, Wolf Bone contends that Eddins intended to convey to Borden a
    temporary 1/2 interest in his reserved 1/8 royalty under the Ross Lease, as evidenced by paragraph
    5 in the deed, which Wolf Bone contends was extinguished when the Ross Lease terminated.
    Second, Wolf Bone contends that Eddins intended to convey to Borden a 1/16 mineral interest in
    his possibility of reverter under the Ross Lease, as evidenced by the language used in paragraph 6,
    which expressly states that upon the expiration of that lease, “an undivided one sixteenth (1/16) of
    the lease interest and all future rentals on said land for oil, gas and other mineral privileges shall be
    owned by said [Borden], he owning one sixteenth of all oil, gas and other minerals in and under
    said lands, together with no interest in all future rents.” Thus, according to Wolf Bone, upon the
    expiration of the Ross Lease, this left Borden with a 1/16 mineral interest, which in turn, gave
    Borden and his successors a corresponding 1/16 floating royalty interest. Wolf Bone contends
    that this is in effect the only way to reconcile these two conflicting fractions, and to successfully
    26
    harmonize all provisions in the lease.
    Wolf Bone is correct that courts have long held that a grantor may in fact convey two
    separate estates to a grantee in a mineral deed, which may or may not be of equal size or duration—
    a concept often referred to as the “two estates” doctrine. Thus, in its most recent opinion on the
    subject, the Supreme Court in Hysaw noted that a grantor could convey, either through the same or
    separate instruments, an “undivided portion of the mineral estate and a separate royalty interest,
    and the royalty interest conveyed may be larger or smaller than the interest conveyed in the
    minerals in place.”

    (citing 
    Luckel, 819 S.W.2d at 463
    ); see also
    
    Richardson, 185 S.W.2d at 564
    (construing deed as conveying two separate and distinct estates in
    the land); Pan Am. Petroleum Corp. v. Texas Pac. Coal & Oil Co., 
    340 S.W.2d 548
    , 557
    (Tex.Civ.App. – El Paso 1960, writ ref’d n.r.e.) (two estates were conveyed when the deed clearly
    stated that grantees were to be given a temporary 1/4 royalty interest in three existing leases on the
    property, as well as a permanent 1/32 interest in the mineral estate).
    Wolf Bone concludes the deed conveyed two separate estates of unequal sizes by focusing
    solely on only two provisions in the deed: paragraph 5, which Wolf Bone contends granted
    Borden the temporary 1/2 royalty interest under the Ross Lease, and paragraph 6, which Wolf
    Bone contends gave Borden a permanent 1/16 mineral interest in Eddins’ possibility of reverter
    upon the expiration of the Ross Lease. Like the Greer Group’s approach, Wolf Bone’s approach
    is flawed by essentially ignoring the language in the five other remaining provisions in the deed.
    Again, we reject this approach because it contravenes the Supreme Court’s mandate that we look
    to all provisions in a deed in determining the parties’ intent in conveying mineral interests.
    Importantly, we note that in at least three other provisions in the lease, Eddins used
    27
    language indicating his intent to make an immediate transfer of a portion of his mineral interests to
    Borden, and not just in a transfer of his possibility of reverter. First, in paragraph 1 of the deed
    Eddins states that he was conveying to Borden a 1/16 interest in the “minerals in and under, and
    that [which] may be produced” from the land described in the deed. This is the classic language
    of a mineral conveyance, and there is no indication in paragraph 1 that Eddins intended to convey
    only his future mineral interests in the possibility of reverter in that paragraph. See, e.g., Concord
    Oil 
    Co., 966 S.W.2d at 459
    . Similarly, paragraph 3 also appears to convey an immediate mineral
    interest to Borden, when it states that Borden is to have the “right of ingress and egress at all times
    for the purpose of mining, drilling, and exploring said land for oil, gas and other minerals, and
    removing the same therefrom.” The Supreme Court has recognized that a conveyance purporting
    to transfer to a grantee the right of ingress and egress for the purpose of mining, drilling and
    exploring is by definition a mineral interest rather than a royalty interest. 
    Id. There is
    nothing in
    the language of paragraph 3 that would lead us to conclude that Eddins intended to convey only a
    future mineral interest in his possibility of reverter in this paragraph, and it instead appears to be an
    immediate conveyance of a mineral interest.
    The only paragraph that appears to discuss Borden’s future interest in the possibility of
    reverter is found in paragraph 6, which describes the nature of the estate that Borden is to have
    upon expiration of the Ross Lease. A close examination of paragraph 6 reveals that Eddins was
    expressing his intent to convey both a portion of his future interest in the possibility of reverter to
    Borden, together with an intent to convey present mineral interest to Borden as well.                 In
    particular, paragraph 6 contains a sentence with two separate clauses, which appear to be referring
    to separate estates.
    28
    The first clause in the sentence is a statement that upon the expiration of the Ross Lease,
    “an undivided one sixteenth (1/16) of the lease interest and all future rentals on said land for oil,
    gas and other mineral privileges shall be owned by said [Borden] (emphasis added).” As Wolf
    Bone appears to recognize, this clause conveys a percentage of the possibility of reverter to
    Borden. However, in the second clause, the deed adds that, “he [Borden] owning one sixteenth of
    all oil, gas and other minerals in and under said lands, together with no interest in all future rents
    (emphasis added).” This second clause would have been entirely unnecessary and redundant if
    Eddins only intended to memorialize that he was conveying to Borden a future mineral interest
    (i.e., an interest in the possibility of reverter), and it appears that Eddins was instead intending to
    memorialize his intent that he was conveying an immediate mineral interest to Borden as well.
    This interpretation is strengthened by the fact that the two clauses appear to convey mineral estates
    that have different attributes. The first clause, which appears to be giving Borden an interest in
    the future possibility of reverter, includes an interest in “all future rentals,” whereas the second
    clause, which appears to be giving Borden a present mineral interest, states that Borden has “no
    interest in all future rents.”    These seemingly conflicting statements can be resolved and
    harmonized only by concluding that these two clauses conveyed two separate estates to
    Borden—the future interest in the possibility of reverter (with its inclusion of future rents) and the
    present mineral interest (without any such inclusion).
    Finally, Wolf Bone’s interpretation would have us ignore a portion of paragraph 4, which
    states that Borden was “purchasing one-half (1/2) of the royalty [] one half (1/2) of the minerals,
    produced in and from wells or other operations situated on the specific tract of land described in
    this instrument [emphasis added],” the latter portion of which utilizes clear language of a mineral
    29
    conveyance. Wolf Bone argues that this paragraph should be read solely in conjunction with
    Borden’s rights under the Ross Lease, and should be construed as a reiteration that Borden was
    being given a 1/2 royalty interest in the Ross Lease. This interpretation, however, ignores that
    paragraph 4 contains references to both a 1/2 royalty interest and a 1/2 mineral interest, the latter of
    which would have no place in discussing a party’s royalty interest under a lease. Further,
    paragraph 4 contains no indication that the interests being discussed in that paragraph were
    intended to only apply to Borden’s interest in the Ross Lease. To the contrary, the sequence in
    which the two paragraphs are found in the deed belies any such interpretation, because the first
    mention of the Ross Lease comes in paragraph 5, after the discussion of Borden’s “purchase” of
    his mineral interests in paragraph 4. Instead, we conclude that Paragraph 4 was an expression that
    Borden was purchasing an immediate mineral interest with a corresponding royalty interest, which
    harmonizes this paragraph with paragraphs 1, 3, 6, and 7 of the deed, as described above. In turn,
    paragraph 6 not only reiterates that Borden was making an immediate purchase of a mineral
    interest, but that he also had an interest in Eddins’ future possibility of reverter as well. And
    finally, paragraph 5 is a recognition that the purchase of these various mineral interests is being
    made subject to the Ross Lease. It is only by interpreting the 1927 deed in this manner, as
    conveying both a present and future mineral estate to Borden, that we can reconcile every
    provision in the lease, and thereby harmonize all of those seemingly conflicting provisions in order
    to ascertain the parties’ intent, as we are required to do. See, e.g., 
    Hysaw, 483 S.W.3d at 13
    .
    Harmonizing the Fractions
    Although the 1927 Deed at various times uses the 1/16 fraction and at other times uses the
    1/2 fraction, these seemingly conflicting fractions are readily harmonized by resorting to the
    30
    “legacy of the 1/8th royalty” doctrine and the estate misconception doctrine. As explained above,
    in light of the “ubiquitous” standard 1/8 royalty interest, land owners at the time this deed was
    executed labored under the mistaken impression that their standard royalty interest would always
    and forever be a 1/8 interest (i.e., the “legacy of the 1/8th royalty”), and thereby often used the 1/8
    fraction and multiples thereof to express the fraction of their interest that they intended to convey
    to a third party. Similarly, as recognized by the “estate misconception” doctrine, at the time of
    this conveyance, landowners often labored under the mistaken impression that they only owned a
    1/8 mineral interest in the possibility of a reverter under a lease, when in fact the reverter was the
    equivalent of the entire mineral estate. See, e.g., 
    Hysaw, 483 S.W.3d at 10
    -11. Therefore,
    grantors during that time period also used “multiples of 1/8” as a shorthand expression to indicate
    the interest they intended to convey in a possibility of a reverter.
    Applying these two doctrines in conjunction, we conclude that Eddins used the fraction
    1/16 in paragraphs 1 and 6 as a shorthand for expressing that he intended to convey 1/2 of what he
    believed was his remaining 1/8 mineral interest in the land, i.e., 1/2 of that purported 1/8 interest.
    This enables us to harmonize the use of the 1/2 fraction in paragraph 4, which indicated Borden
    was purchasing a 1/2 mineral interest in the land, which corresponded with the 1/2 floating royalty
    interest that would directly derive from that mineral interest. See, e.g., 
    Garrett, 299 S.W.2d at 906
    (where deed used both the 1/16 fraction and the 1/2 fraction as various times, the court
    concluded that grantor’s use of a 1/16 fraction was a shorthand expression of the grantor’s intent to
    convey 1/2 of his 1/8 royalty interest, thereby harmonizing the deed’s use of the conflicting
    fraction in other provisions in the deed); see also 
    Luckel, 819 S.W.2d at 462
    (court applied the
    “legacy of the 1/8th royalty” in determining that the 1/32 fraction used in the granting clause of the
    31
    deed represented a shorthand way of expressing that grantor intended to convey her 1/4 interest in
    the “usual” 1/8 royalty retained in oil and gas leases at the time, giving the grantee a 1/4 floating
    royalty interest, allowing court to harmonize the deed’s use of the 1/4 fraction in other provisions
    in the deed); 
    Hysaw, 483 S.W.3d at 15-16
    (applying the “legacy of the 1/8th royalty,” where
    grantor conveyed 1/3 of 1/8 of her interests under an existing lease to each of her children in her
    will, to conclude that she intended to use the fraction 1/8 as a “shorthand” for the entire royalty
    interest that she retained under the lease, thereby giving each grantee equal shares of her interest).
    This interpretation not only harmonizes all of the provisions in the deed, but also is further
    strengthened by the fact that Borden was given the same size royalty interest under the Ross Lease
    (an express 1/2 royalty interest), as he was under future leases. We find this to be consistent with
    Eddins’ intent, since there is simply nothing in the 1927 deed to indicate that Eddins intended to
    give Borden a fairly substantial 1/16 share of production under the Ross Lease (1/2 of his 1/8
    royalty), but then significantly reduce that share under any future leases to 1/16 of his 1/8 royalty
    interest, which would amount to a 1/96 share of production. Such a radical change in the interest
    being conveyed would not be expected in a conveyance of this nature. Therefore, we decline to
    adopt such an interpretation of the 1927 deed. See, e.g., 
    Garrett, 299 S.W.2d at 906
    -07 (finding
    nothing in the language of the deed that would warrant a conclusion that the grantor intended to
    reduce the grantee’s existing royalty interest in future leases from what he conveyed under an
    existing lease).
    We therefore conclude that Eddins intended to convey one estate to Borden, consisting of a
    permanent 1/2 mineral interest, existing both before and after the expiration of the Ross Lease,
    which included a corresponding 1/2 floating royalty interest in both existing and future leases.
    32
    See, e.g., Concord Oil 
    Co., 966 S.W.2d at 457
    (finding that the grantor intended to convey one
    estate, consisting of a 1/2 mineral interest, which included a 1/2 royalty interest). Although we
    arrive at this conclusion based on a different analysis than used by the parties or the trial court, the
    answer to the trial court’s certified question is the same—the Borden Successors have a floating
    1/2 royalty interest under the terms of the 1927 deed (derived from their 1/2 mineral interest),
    which in turn entitles them to 1/2 of the 1/4 royalty set by the Patriot Leases, or in other words, a
    1/8 share of the total production under those leases. We overrule the single issue on appeal.
    CONCLUSION
    The trial court’s judgment is affirmed.
