    Sundance Energy Oklahoma, LLC, brought suit against Dan D. Drilling
    Corporation for damages resulting from the total loss of an oil and gas well. A jury
    found against Dan D., and the district court denied its motion for a new trial. Dan D.
    appeals, arguing the district court erred in (1) giving one jury instruction and
    omitting another; (2) admitting certain evidence; and (3) awarding Sundance
    attorney’s fees. Finding no reversible error, we affirm.
    BACKGROUND
    Sundance contracted with Dan D. to drill seven oil and gas wells in June 2012.
    For each of those wells, Sundance and Dan D. executed a single-well contract
    (collectively, the June 2012 contracts). The June 2012 contracts used an industry-
    standard International Association of Drilling Contractors (IADC) form, with only
    minor changes to the form’s language. Notably, in each of the June 2012 contracts,
    the parties left section 14 of the IADC form, titled “RESPONSIBILITY FOR LOSS
    OR DAMAGE, INDEMNITY, RELEASE OF LIABILITY AND ALLOCATION OF
    RISK,” substantially unaltered. App. vol. 16F, 3813. In relevant part, that section
    provides, “In the event the hole should be lost or damaged, [Sundance] shall be solely
    responsible for such damage to or loss of the hole.” Id. at 3814. That section further
    explains:
    [I]t is the intent of [the] parties hereto that all releases, indemnity
    obligations and/or liabilities assumed by such parties under [the] terms of
    the Contract . . . be without limit and without regard to the cause or causes
    thereof, including but not limited to . . . the negligence of any degree or
    character (regardless of whether such negligence is sole, joint or
    concurrent, active, passive or gross) of any party or parties . . . .”
    2
    Id.
    Dan D. ultimately drilled only two of the seven wells due to Sundance’s
    inability to secure proper leases and drilling permits for the other five. In lieu of the
    undrilled wells, Sundance asked Dan D. to drill a different group of wells—including
    one known as the Rother well—and hired Tres Management to provide engineering
    services and an onsite supervisor known as a company man for this work. In early
    December 2012, Dan D. signed a multi-well contract (the December 2012 contract)
    for these new wells. And although Sundance received the signed December 2012
    contract—which included terms similar to those contained in the June 2012
    contracts—Sundance asserts that its in-house counsel never reviewed or signed the
    contract before Dan D. began work on the Rother well.
    Despite the absence of an executed contract, Dan D. began drilling the Rother
    well on December 2, 2012, under the supervision of Tres’ company man. On
    December 9, 2012, Dan D.’s drill pipe became stuck in the hole. After several failed
    attempts to remove the drill pipe, the company man instructed Dan D.’s employees to
    stop pulling on the stuck pipe. A driller on the rig ignored these instructions and
    continued to try to remove the equipment. During these attempts, the drilling line—a
    thick, coiled steel rope routed through derrick and used to raise or lower the drill
    string using a pulley system—parted, and portions of the drill rig known as the
    traveling blocks fell on the driller, killing him. A medical examiner later determined
    that the driller had significant quantities of methamphetamine in his blood at the time
    of the accident.
    3
    The Occupational Safety and Health Administration (OSHA) suspended
    operations for 12 days while it investigated the accident. In its June 19, 2014
    technical report, OSHA explained that the accident resulted from fatigue failure of
    the drilling line—a progressive failure occurring over time. The report concluded that
    “[a] proper ‘cut and slip’ program, visual inspection and attention to the ton-mile
    history of the rope would have limited the wear accumulated by this drill line.”1 App.
    vol. 15B, 3469. OSHA thus issued Dan D. a citation for failing to inspect and
    properly maintain the drilling line. Dan D. and OSHA settled the citation, and OSHA
    reduced the fine in return for Dan D. taking corrective actions at the drill site.
    Following OSHA’s investigation, Sundance replaced Tres’ company man.
    Under the new company man’s supervision, Dan D. attempted to fish out the drill
    pipe stuck in the Rother well. But the wellbore had deteriorated during the 12-day
    shutdown, making it impossible to remove the drill pipe. Sundance ultimately
    decided to plug and abandon the Rother well, resulting in a total loss of the hole.
    Sundance sued Dan D. for damages, asserting that Dan D.’s negligence, gross
    negligence, and breach of implied contract to drill the well in a workmanlike manner
    resulted in the loss of the hole. Before trial, Dan D. filed several motions in limine,
    including one objecting to the admission of two OSHA narratives as hearsay, and one
    objecting to the admission of toxicology evidence showing that the deceased driller
    had methamphetamine in his blood at the time of his death. The district court denied
    1
    Slipping and cutting is a process used to repair worn portions of the line that
    is generally performed before the start of each new well.
    4
    the motion to suppress the toxicology evidence, and denied in part the motion to
    suppress the OSHA narratives, agreeing to admit only certain portions of those
    documents.
    At the subsequent jury trial, Sundance offered testimony indicating that a
    driller typically keeps a log of the drilling line’s “ton miles,” i.e., the work done by
    the line, as measured by the load lifted in tons and the distance lifted or lowered in
    miles. In fact, Sundance’s expert testified, Dan D.’s failure to track and log the ton
    miles of the drilling line used at the Rother well was “unheard of” in the industry.
    App. vol. 11, 2072. The expert further opined that Dan D. should have slipped and
    cut the drilling line before or during the drill to prevent the accident. Sundance relied
    on this testimony at closing to argue that Dan D.’s gross negligence caused the line’s
    failure or, alternatively, that Dan D. breached an implied contract to drill the Rother
    well in a workmanlike manner. And, Sundance maintained, the ensuing 12-day
    shutdown caused the wellbore deterioration and ultimately resulted in the total loss of
    the hole.
    For its part, Dan D. argued in closing that the jury should attribute most of the
    fault not to Dan D., but to Tres and its company man. In any event, Dan D. asserted,
    the exculpatory provisions provided in the IADC standard contract—which state that
    Sundance is liable for any damage to or loss of the hole, including any loss resulting
    from Dan D.’s gross negligence—formed part of an implied contract between Dan D.
    and Sundance. And under these provisions, Dan D. maintained, it wasn’t liable for
    the loss of the well.
    5
    Dan D. also argued to the district court that Sundance owed a non-delegable
    duty to Dan D., and, accordingly, that any negligence of its independent contractor—
    i.e., Tres—was imputable to Sundance. But when Dan D. asked the district court to
    instruct the jury that it should therefore impute any of Tres’ negligence to Sundance,
    the district court denied its request, noting that it “just didn’t see sufficient evidence
    that this was a non-delegable duty.” App. vol. 11, 2143. And over Dan D.’s
    objection, the district court instructed the jury that if it found Dan D. was grossly
    negligent, the jury shouldn’t consider whether an implied contract between the
    parties incorporated the exculpatory provisions of the IADC standard contract. The
    district court based this instruction on its understanding that, under Oklahoma law, a
    provision that ostensibly exculpates a grossly negligent party from liability is invalid
    and unenforceable.
    The jury returned a verdict in favor of Sundance, finding that Dan D. was
    grossly negligent and breached an implied contract to drill the hole in a workmanlike
    manner. And because the jury found Dan D. grossly negligent, the jury didn’t
    consider whether the implied contract incorporated the exculpatory provisions of the
    IADC standard contract. Ultimately, the jury attributed 75% of the loss to Dan D.’s
    negligence and 25% of the loss to Tres’ negligence and awarded Sundance $1.2
    million in damages.
    Dan D. filed a motion for a new trial under Federal Rule of Civil Procedure
    59(a), arguing the court erred by (1) precluding the jury from considering whether the
    exculpatory provisions in the IADC form were part of the implied contract; (2) ruling
    6
    that Sundance didn’t have a non-delegable duty to Dan D. and that Tres’ negligence
    therefore wasn’t imputable to Sundance; and (3) admitting the toxicology evidence
    and the OSHA narratives. The district court denied the motion and Dan D. appealed
    that order.2
    Sundance then filed a motion for attorney’s fees under Okla. Stat., tit. 12,
    § 940(A), which allows a prevailing party to collect reasonable attorney’s fees in
    “any civil action to recover damages for the negligent or willful injury to property.”
    The district court concluded that § 940(A) applied because Sundance brought this
    civil action to recover damages for Dan D.’s negligent injury to the Rother well.
    Thus, the court awarded Sundance attorney’s fees. Dan D. also appealed that order,
    and we consolidated the two appeals.
    DISCUSSION
    I.     The district court didn’t err in instructing the jury.
    Dan D. first argues that the district court erred in (1) instructing the jury that it
    need not decide whether the allocation of risk provisions formed part of the implied
    contract if it found Dan D. was grossly negligent, and (2) refusing to instruct the jury
    that it should impute Tres’ negligence to Sundance. We “review for abuse of
    2
    In its first Notice of Appeal, Dan D. indicated that it was appealing only the
    district court’s order denying its motion for a new trial, rather than the district court’s
    entry of judgment on the jury verdict. A notice of appeal designating a ruling on a
    postjudgment motion is typically sufficient to appeal the judgment itself. See, e.g.,
    Jones v. Nelson, 
    484 F.2d 1165
    , 1168 (10th Cir. 1973); Cheney v. Moler, 
    285 F.2d 116
    , 117-18 (10th Cir. 1960). Accordingly, “we will treat this appeal as if” Dan D.
    took it “from the entry of judgment on the jury verdict.” Grubb v. Fed. Deposit Ins.
    Corp., 
    868 F.2d 1151
    , 1154 n.4 (10th Cir. 1989).
    7
    discretion a district court’s decision not to give a tendered jury instruction” and
    “review de novo whether the instructions as a whole accurately informed the jury of
    the governing law.” Sherouse v. Ratchner, 
    573 F.3d 1055
    , 1060 (10th Cir. 2009). An
    incorrect jury instruction “requires reversal, however, ‘only if the error is determined
    to have been prejudicial, based on a review of the record as a whole.’” 
    Id. at 1059
    (quoting Durfinger v. Artiles, 
    727 F.2d 888
    , 895 (10th Cir. 1984)).
    A.     The Gross-Negligence Instruction
    The jury found Dan D. was grossly negligent—i.e., that Dan D. failed to act
    with even “slight care and diligence.” 
    Okla. Stat. tit. 25, § 6
    . And the district court
    instructed the jury that if it so found, it shouldn’t consider whether any implied
    contract between the parties included the exculpatory provisions of the IADC form
    contract. To support this instruction, the district court explained that “the last word[]
    in the Oklahoma Supreme Court was that gross negligence was sufficient to vitiate an
    exculpatory clause.” App. vol. 11, 2145. Dan D. disagrees, arguing that the district
    court’s gross-negligence instruction was erroneous because provisions exculpating
    gross negligence aren’t per se invalid under Oklahoma law. Consequently, Dan D.
    argues, the district court should have granted it a new trial on this basis.
    In this diversity action, we look to the rulings of the Oklahoma Supreme Court
    to determine the applicable law governing the enforceability of exculpatory
    provisions, “and, if no such rulings exist, [we] must endeavor to predict how that
    high court would rule.” See Johnson v. Riddle, 
    305 F.3d 1107
    , 1118 (10th Cir. 2002).
    In its order denying Dan D.’s motion for a new trial, the district court relied on
    8
    Schmidt v. United States, 
    912 P.2d 871
     (Okla. 1996), as the most relevant case
    governing exculpatory provisions in Oklahoma. There, the United States District
    Court for the Western District of Oklahoma certified a question to the Oklahoma
    Supreme Court regarding whether an exculpatory clause was valid and enforceable.
    Id. at 872.3 In answering that question, the court held in part that “exculpatory
    clauses cannot relieve one from liability for fraud, willful injury, gross negligence or
    violation of the law.” Id. (emphasis added). It later reiterated that an exculpatory
    “clause will never avail to relieve a party from liability for intentional, willful or
    fraudulent acts or gross, wanton negligence.” Id. at 874 (second emphasis added).
    Despite the breadth of the Oklahoma Supreme Court’s statements in Schmidt and
    their seemingly clear application to the case at hand, Dan D. insists these statements were
    mere dicta because the underlying facts in the case involved ordinary (not gross)
    negligence, and thus the statements weren’t essential to its holding. But in Schmidt, the
    Oklahoma Supreme Court didn’t rule on the merits of the underlying case, which
    arguably involved only ordinary negligence. See 912 P.2d at 872. That was the task of the
    Western District of Oklahoma. Instead, the Oklahoma Supreme Court answered a
    3
    Although Schmidt dealt solely with a personal injury claim, see 912 P.2d at
    872, rather than negligent destruction of property, Dan D. doesn’t argue that
    Oklahoma law would distinguish between the two types of injuries. Moreover, in
    concluding that exculpatory clauses can’t relieve one from liability for acts of gross
    negligence, the Oklahoma Supreme Court cited approvingly cases that examined such
    clauses in contexts outside of personal injury claims. See id. at 874 & n.15 (citing
    Wolf v. Ford, 
    644 A.2d 522
    , 528 (Md. 1994) (bad stock market investments);
    Manhattan Co. v. Goldberg, 
    38 A.2d 172
    , 174 (D.C. 1944) (loss of property)).
    Accordingly, we find Schmidt informative, notwithstanding the different injuries
    involved.
    9
    certified question about the validity of exculpatory clauses under Oklahoma law
    generally. Its statements that exculpatory clauses can’t relieve one from liability for gross
    negligence were therefore essential to its holding in fully answering that question. Thus,
    we decline to treat the statements as dicta. Moreover, even if we characterize the
    Oklahoma Supreme Court’s comments as dicta, those comments are nonetheless good
    indicators of “how that high court would rule.” See Johnson, 
    305 F.3d at 1118
    .
    Dan D. further argues that what it characterizes as Schmidt’s dicta shouldn’t
    control this case because the Oklahoma Supreme Court has repeatedly used the term
    “gross negligence” imprecisely—sometimes to refer to acts that are comparable to willful
    conduct, and sometimes to refer to conduct that is simply a step above ordinary
    negligence. Thus, Dan D. maintains, Schmidt “is unclear and not a reliable source of
    Oklahoma law.” Aplt. Br. 16. But as Sundance points out, Okla. Stat., tit. 25 § 6 has long
    defined gross negligence as “the want of slight care and diligence.”4 And we see no
    indication that the Oklahoma Supreme Court misapplied this well-established statutory
    definition when answering the certified question in Schmidt.5
    4
    This is the same standard the jury applied in the instant case. See App. vol. 4,
    812 (instructing jury that “[g]ross negligence is the failure to exercise slight care and
    diligence”).
    5
    The district court also relied on the Oklahoma Supreme Court’s pre-Schmidt
    decision in Elsken v. Network Multi-Family Sec. Corp., 
    838 P.2d 1007
     (Okla. 1992).
    There, the court noted that “[c]ourts have refused to uphold limitation of liability
    clauses where the defendant’s conduct constituted gross negligence.” Id. at 1009.
    Dan. D. characterizes this remark as dicta. We need not decide what weight to give
    this statement, however, because Schmidt settled any lingering questions left by
    Elsken.
    10
    Dan D. also offers what it characterizes as multiple “[c]ompelling [r]easons” to
    conclude that the Oklahoma Supreme Court wouldn’t invalidate the provisions contained
    in section 14 of the IADC form contract. Aplt. Br. 16. For example, Dan D. argues that
    (1) the court has routinely expressed a desire to allow parties the freedom to contract;
    (2) the provisions are industry standard; (3) the exculpatory provisions run both ways;
    (4) under Oklahoma law, gross negligence differs from negligence only in degree and not
    in kind; and (5) the exculpatory provisions avoid lengthy and expensive litigation.
    Even if these points have some appeal, they aren’t enough to overcome Schmidt’s
    clear directive. See Flores v. Monumental Life Ins. Co., 
    620 F.3d 1248
    , 1250 (10th Cir.
    2010) (“As a federal court sitting in diversity, our task is ‘simply to “ascertain and
    apply”’ Oklahoma law, attempting to ‘predict what the state’s highest court would do’ if
    faced with the specific issues before us on appeal.” (quoting Wankier v. Crown Equip.
    Corp., 
    353 F.3d 862
    , 866 (10th Cir. 2003))). Because Schmidt controls, we decline to set
    aside the jury verdict based on the gross-negligence instruction.6
    6
    Dan D. filed a motion asking this court to certify the gross-negligence
    question to the Oklahoma Supreme Court. Oklahoma allows for such a procedure “if
    the answer may be determinative of an issue” and “there is no controlling decision of
    the Supreme Court or Court of Criminal Appeals, constitutional provision, or statute
    of this state.” Okla. Stat., tit. 20, § 1602; see also 10th Cir. R. 27.2 (allowing
    certification). But we have cautioned that “we apply judgment and restraint before
    certifying,” and that “we will not trouble our sister state courts every time an
    arguably unsettled question of state law comes across our desks.” Pino v. United
    States, 
    507 F.3d 1233
    , 1236 (10th Cir. 2007). Instead, “[w]hen we see a reasonably
    clear and principled course, we will seek to follow it ourselves.” 
    Id.
     For the reasons
    discussed, Schmidt answered the question Dan D. seeks to certify, see 912 P.2d at
    872, 874, and we deny Dan D.’s motion.
    11
    B.     The Non-Delegable-Duty Instruction
    Dan D. proposed two jury instructions that would have directed the jury to
    impute Tres’ negligence to Sundance because, Dan D. argued, Sundance owed a non-
    delegable duty to Dan D. The district court disagreed that Sundance owed Dan D. a
    non-delegable duty and thus declined to give the proposed instructions. Dan D.
    insists the district court’s reasoning was flawed under Oklahoma law. And Dan D.
    argues the district court should have thus granted it a new trial on this basis. But even
    if we agree with Dan D. that the district court erred by not instructing the jury on the
    non-delegable duty rule, the error didn’t prejudice Dan D. See McInnis v. Fairfield
    Cmtys., Inc., 
    458 F.3d 1129
    , 1140 (10th Cir. 2006) (explaining that failure to give
    jury instruction is reversible only if prejudicial).
    Sundance sought relief on two separate theories: gross negligence and breach
    of implied contract. As the district court noted, the jury found for Sundance on both
    claims. And the jury’s verdict for Sundance on the breach of implied contract claim
    independently supports the jury’s award of damages, because under Oklahoma law
    there is no reduction of damages for a breach of contract claim in light of a party’s
    contributory negligence. See 
    Okla. Stat. tit. 23, § 21
     (stating that the measure of
    damages for a breach of contract “is the amount which will compensate the party
    aggrieved for all the detriment proximately caused thereby”); Chi., R.I. & P. Ry. Co.
    v. Rogers, 
    159 P. 1132
    , 1133 (Okla. 1916) (explaining that contributory negligence
    doesn’t apply to contractual relations); see also Fortier v. Dona Anna Plaza Partners,
    
    747 F.2d 1324
    , 1337 (10th Cir. 1984) (concluding that district court didn’t err in
    12
    failing to reduce plaintiff’s breach of contract damages in light of its contributory
    negligence “because contributory negligence has no place in contract and fraud
    actions”).
    Accordingly, regardless of whether the jury imputed Tres’ negligence to
    Sundance or if imputation might have affected the underlying negligence award, any
    error in the district court’s refusal to instruct the jury that Sundance owed a non-
    delegable duty to Dan D. wasn’t prejudicial because such imputation wouldn’t have
    affected the breach of contract award.
    Dan D. nonetheless argues that the court’s failure to give the instruction was
    prejudicial because “if the implied contract was to drill the well safely and [the
    company man’s] and Tres’ actions were imputable to Sundance, then” the district
    court should have instructed the jury “that such failure[s] by Sundance’s
    representatives were themselves breaches of the contract, thereby precluding any
    recovery on the contract claim.” Aplt. Br. 22.
    Although Dan D. challenges on appeal the gross-negligence jury instructions,
    Dan D. doesn’t otherwise challenge the instructions related to the terms of the
    implied contract. And the jury’s verdict in light of those unchallenged instructions
    establish that the only terms of the implied contract at issue—notwithstanding the
    applicability of section 14 of the IADC form—were that Dan D. would drill the
    Rother well in a good and workmanlike manner and that Sundance would pay Dan D.
    for its work. There is simply no basis for Dan D.’s assertion that Sundance had a duty
    to drill the well safely. Thus, we disagree with Dan D.’s assertion that if the non-
    13
    delegable duty rule applied, then the district court would have instructed the jury
    “that [any] failure[s] by Sundance’s representatives were themselves breaches of the
    contract.” Aplt. Br. 22. Accordingly, we also decline to set aside the jury verdict
    based on the non-delegable-duty instruction.
    II.   The district court didn’t err in admitting the OSHA narratives or the
    toxicology evidence.
    Dan D. next argues that the district court erred by admitting the OSHA
    narratives and the toxicology evidence. “We review a district court’s rulings on
    evidentiary matters and motions in limine for abuse of discretion.” Seeley v. Chase,
    
    443 F.3d 1290
    , 1293 (10th Cir. 2006). If the district court erroneously admitted
    evidence, we will set aside a jury verdict “only if the [admission] prejudicially affects
    a substantial right of a party.” 
    Id.
     Erroneously admitted evidence is prejudicial “if we
    can reasonably conclude that without the evidence, there would have been a contrary
    result.” 
    Id.
     (quoting Smith v. Atl. Richfield Co., 
    814 F.2d 1481
    , 1487 (10th Cir.
    1987)).
    Sundance submitted to OSHA a Freedom of Information Act request and
    received two narratives relating to the accident, including one labeled “Fatality
    Narrative” and one labeled “Safety Narrative.” App. vol. 14, 2708, 2718. Dan D.
    argues these two narratives were inadmissible because they are untrustworthy. See
    Fed. R. Evid. 803(8)(B) (stating that the rule against hearsay doesn’t exclude a record
    or statement of public office unless opponent shows “that the source of information
    or other circumstances indicate a lack of trustworthiness”). And Dan D. argues that
    14
    the erroneous admission of the OSHA narratives was prejudicial because no other
    admitted evidence included the derrick hand’s statements that (1) he “heard popping
    noises” coming from the drilling line when the drill pipe was stuck, and (2) he told
    his supervisor about those noises prior to the accident. App. vol. 14, 2716.
    The district court also admitted a medical examiner’s video deposition and his
    corresponding report indicating there was methamphetamine in the deceased driller’s
    blood at the time of the accident. Dan D. argues this evidence is irrelevant and
    inadmissible under Federal Rule of Evidence 401 because there is no reasonable
    certainty that the driller was impaired at the time of the accident and because there is
    no reasonable link between the presence of methamphetamine in the driller’s blood
    and the accident. Dan D. also argues that, even if relevant, this evidence is
    inadmissible under Federal Rule of Evidence 403 because its probative value is
    substantially outweighed by the danger of unfair prejudice; according to Dan D.,
    methamphetamine use “is particularly inflammatory in today’s culture.” Aplt Br. 25.
    And Dan D. argues the erroneous admission of this evidence was prejudicial because
    the evidence represented the “critical tipping point” for the jury. 
    Id.
    We decline to consider whether the narratives were untrustworthy under Rule
    803(8)(B) or whether the methamphetamine evidence was irrelevant under Rule 401
    or unduly prejudicial under Rule 403. Even if we assume the district erred in
    admitting this evidence, Dan D. hasn’t established that, but for the alleged errors,
    “we can reasonably conclude that . . . there would have been a contrary result” at
    trial. Seeley, 
    443 F.3d at 1293
     (quoting Smith, 
    814 F.2d at 1487
    ).
    15
    For one, the district court also admitted into evidence both the OSHA citation
    and the June 19, 2014 technical report and Dan D. doesn’t challenge their admission
    on appeal. The citation indicated that Dan D. committed a “[s]erious” violation by
    failing to adequately inspect and maintain the drilling line “to eliminate failure of
    [the] drilling line wire rope[,] which expose[d] employees to struck-by hazards
    during oil/gas drilling operations.” App. vol. 13B, 2695. Moreover, the June 19, 2014
    technical report and other testimony at trial established that Dan D. failed to keep
    track of the accumulated ton-miles on the drilling line, an oversight that one expert
    testified was “unheard of” in the industry. App. vol. 11, 2072. And Dan D.’s own
    president admitted that Dan D. failed to properly slip and cut the line. Finally,
    Sundance presented evidence demonstrating that the deceased driller ignored
    instructions to stop pulling on the stuck drill pipe, and that during his subsequent,
    unauthorized attempts to remove the pipe, the drilling line failed.
    In short—even setting aside the OSHA narratives and toxicology evidence—
    Sundance presented overwhelming evidence to the jury of Dan D.’s failure to inspect
    and maintain the drilling line, and of the driller’s continued, unauthorized attempts to
    free the stuck drill pipe. There is no basis for concluding that the jury would have
    granted Dan D. a favorable verdict but for the admission of the OSHA narratives and
    methamphetamine evidence. Thus, we decline to set aside the jury verdict based on
    the admission of the OSHA narratives and the toxicology evidence.

    III.   The district court properly awarded Sundance attorney’s fees.
    Finally, Dan D. argues that the district court erred in awarding Sundance
    attorney’s fees. “In diversity cases, attorney[’s] fees are a substantive matter
    controlled by state law,” and “[w]e review the legal principles underlying an award
    de novo.” Combs v. Shelter Mut. Ins. Co., 
    551 F.3d 991
    , 1001 (10th Cir. 2008).
    In any civil action brought under Oklahoma law “to recover damages for the
    negligent or willful injury to property and any other incidental costs related to such
    action, the prevailing party shall be allowed reasonable attorney’s fees.” 
    Okla. Stat. tit. 12, § 940
    (A).7 The use of the word “shall” renders the award of attorney’s fees
    mandatory when an action falls under the purview of § 940(A). See Schaeffer v.
    Shaeffer, 
    743 P.2d 1038
    , 1040 (Okla. 1987).
    Sundance requested attorney’s fees under this statute, arguing that the loss of
    the hole is the type of damage that squarely falls within § 940(A). Sundance
    explained that § 940(A) applies to actions involving the negligent destruction of a
    wellbore, relying on Parks v. American Warrior, Inc., 
    44 F.3d 889
     (10th Cir. 1995),
    Marino v. Otis Engineering Corp., 
    839 F.2d 1404
     (10th Cir. 1988), and Busby v.
    Canon Well Services, Inc., 
    771 P.2d 1016
     (Okla. Civ. App. 1989). The district court
    agreed, finding that the “negligent destruction of an oil and gas well falls within the
    7
    Dan D. doesn’t challenge the reasonableness of the amount awarded, but
    rather only argues that Sundance wasn’t entitled to attorney’s fees in the first
    instance. We thus limit our discussion to the legal question, and express no opinion
    as to the reasonableness of the actual award.
    17
    scope of § 940(A),” and that Sundance, as the prevailing party, was entitled to
    attorney’s fees. App. vol. 5, 1068 (quoting Parks, 
    44 F.3d at 892
    ).
    In challenging the award of attorney’s fees, Dan D. argues § 940(A) applies
    only to actions involving physical damage to property, not to actions involving
    “property rights” generally. Aplt. Br. 26 (quoting Woods Petrol. Corp. v. Delhi
    Pipeline Corp., 
    700 P.2d 1011
    , 1012 (Okla. 1984)). Dan D. thus attempts to
    distinguish the cases Sundance relies on, suggesting those case “involved claims of
    damages stemming from actual physical injury to the well, namely damages to the
    producing formations and reserves.” Id. at 27. And “because there was no evidence
    here of damage to the producing formation or loss of reserves,” Dan D. maintains
    that § 940(A) doesn’t apply to the facts of this case. Id. at 28.
    Although we agree that Woods Petroleum made clear that § 940(A) is limited
    to “actions for damages for the negligent or willful physical injury to property,” 700
    P.2d at 1013, we disagree that this holding precludes attorney’s fees in this case. In
    Woods Petroleum, the Oklahoma Supreme Court reversed an award of attorney’s fees
    in an action involving the defendant’s negligent operation of a flow meter, which
    resulted in a miscalculation of the amount of gas sold to the defendant. Id. at 1012-
    13. The Oklahoma Supreme Court held that § 940(A) didn’t apply because the
    Oklahoma legislature didn’t intend that section to encompass actions involving
    interference with all property rights, but rather to encompass only actions involving
    “physical negligent or willful injury to property.” Id. at 1012.
    18
    In that regard, Woods Petroleum’s facts are distinguishable from the facts here.
    Sundance’s recovery here stemmed not from a mere interference with property rights
    as in Woods Petroleum, but from the physical deterioration of the Rother well during
    the 12-day OSHA investigation. This is precisely the type of “physical injury to
    property” to which the Woods Petroleum court indicated § 940(A) would apply. See
    id. at 1013.
    Indeed, notwithstanding Dan D.’s efforts to distinguish Marino and Busby, we
    find those opinions particularly instructive. In Marino, a well owner brought an
    action against the manufacturer that made and installed a “packer” device in its well.
    
    839 F.2d at 1406
    . After the device became stuck and subsequent attempts to remove
    it destroyed the well, the well owner sought damages against the manufacturer. 
    Id. at 1405-06
    . The jury returned a verdict for the manufacturer, which then sought
    attorney’s fees under § 940(A). Id. at 1412. On appeal, we distinguished Woods
    Petroleum, concluding that § 940(A) applied because the well owner’s alleged injury
    arose from physical damage. Specifically, we explained that the plaintiff’s
    “allegations center around the physical injury to property and thus fall within the
    mandatory coverage of § 940(A) authorizing the recovery of attorney’s fees.” Id. at
    1412-13 (emphasis added).
    Similarly, in Busby an owner of an oil and gas well hired a contractor to
    fracture the well, but the contractor allegedly used the wrong chemical agent,
    resulting in a total loss of the well. 
    771 P.2d at 1016
    . The owner brought an action
    for breach of contract or in the alternative negligence, but the jury found in favor of
    19
    the contractor. 
    Id.
     The contractor then sought attorney’s fees under § 940(A), and on
    appeal the Oklahoma Court of Appeals held that section applied. Id. at 1016-17. That
    court also distinguished Woods Petroleum, explaining:
    The Woods decision did not find that oil or gas was not “property” under
    the provisions of § 940(A), but rather found that the required physical
    injury to the property was not present. In [the well owner’s] action against
    [the contractor], damages were sought for negligent destruction of the oil
    and gas well. In awarding attorney[’s] fees to [the contractor] under the
    provisions of § 940(A), the trial court was presented with actual injury to
    the property itself, and not the broader field of rights in property found to
    be outside the meaning of § 940(A) in Woods Petroleum . . . .
    Id. at 1017 (emphasis added).
    Dan D. argues that these cases are distinguishable because they involved
    “damages to producing formations and reserves.” Aplt. Br. 27. We disagree. In
    concluding that § 940(A) applied, neither Marino nor Busby relied on whether the
    producing formations and reserves sustained damage; rather, both courts looked to
    whether the property at issue sustained physical injury. See Marino, 
    839 F.2d at 1412-13
    ; Busby, 
    771 P.2d at 1017
    . Here, as in Marino and Busby, but unlike in
    Woods Petroleum, Sundance sought damages resulting from the physical injury to an
    oil and gas well: namely, the deterioration of the wellbore during the 12-day OSHA
    investigation. Sundance, as the prevailing party, was thus entitled to reasonable
    attorney’s fees. See Marino, 
    839 F.2d at 1412-13
     (explaining that in case involving
    negligent destruction of oil and gas well, award of attorney’s fees to prevailing party
    under § 940(A) is “mandatory”).
    Affirmed.
