ExxonMobil Oil Corporation, formally Mobil Oil Corporation (Mobil), appeals the district court’s certification of a class action against it by Mobil’s oil and gas lessors of Kansas minerals within the Hugoton Field, or by the successors in interest to such lessors, alleging breach of express and implied covenants by Mobil in the purported improper deduction of expenses from the payment of royalties to lessors. Mobil contends the district court abused its discretion in certifying a class because it failed to rigorously analyze the requirements of K.S.A. 60-223, that choice-of-law issues and variations in the circumstances surrounding execution of individual leases defeat the predominance of any common issues of law or fact, and that these individual issues would make *874 management of a class action difficult if not impossible. Concluding there was no abuse of discretion by the district court, we affirm the class certification and remand for further proceedings.
Factual and Procedural Background
Plaintiffs initially sought to certify a class action on behalf of interest owners of minerals burdened by 1,200 leases on acreage within the areal extent of the Kansas Hugoton Field, whose gas flowed through the Bushton gathering system owned by ONEOK. The action alleged that Mobil had breached express and implied contractual obligations by deducting from royalty payments a prorata portion of the amount paid by Mobil to ONEOK for services necessary to gather the gas and transport it to the processing plant. These claims were expanded 3 years later to include claims of the additional mineral interest owners whose gas flowed through the Jayhawk Plant on the Hickok gathering system owned by Mobil. Counsel indicated at oral argument that the scope of the litigation now involves approximately 2,000 leases and more than 5,000 potential class members.
After Mobil’s attempts to remove the action to federal court failed, discovery was conducted, the certification issue was joined, and the district court conducted an evidentiary hearing. Following posttrial submissions from the parties, the court entered its 21-page journal entry certifying a class action under K.S.A. 60-223(b)(3) and defining the class as:
“ ‘All persons or concerns owning mineral interests in lands located in the areal confines of the Kansas Hugoton Gas Field, burdened by oil and gas leases owned in whole or in part by defendant insofar as such leases are productive of gas from above the base of the Panoma Council Grove Field, the gas from which has been subject to the Gathering Agreement, including the instrumentalities of the United States of America and federally chartered corporations, such as, but not limited to, the Farm Credit Bank of Wichita and the Federal Land Bank, but excluding the United States of America insofar as its mineral interests are managed by the Mineral Management Service.’ ”
On September 1,2009, Mobil filed its application with this court to take an interlocutory appeal pursuant to K.S.A. 60-223(f). This court granted the application and stayed the district court pro *875 ceedings pending resolution of this interlocutory appeal. Mobil then timely filed its notice of appeal.
Standards for Class Certification and Appellate Review Thereof
There are four statutory threshold prerequisites to bringing a class action in Kansas. A class action is only proper if (1) the number of class members is so large that joinder of all mеmbers is impracticable; (2) the class claims present common questions of fact or law; (3) the named parties’ claims and defenses are representative of the claims and defenses of the other class members; and (4) the class representatives will fairly and adequately protect the interests of the class as a whole. K.S.A. 60-223(a). In shorthand, the threshold elements are identified as “(1) numerosity, (2) commonality, (3) typicality, and (4) adequacy of representation.”
Dragon v. Vanguard Industries, Inc.,
In addition to meeting all the threshold elements, a putative class plaintiff must establish that a class action is maintainable under one of the three provisions of K.S.A. 60-223(b). Here, plaintiffs rely on the criteriа of K.S.A. 60-223(b)(3), which state:
“[T]he court finds that the questions of law or fact common to the members of the class predominate over any questions affecting only individual members, and that a class action is superior to other available methods for the fair and efficient adjudication of the controversy. The matters pertinent to the findings include: (A) The interest of the members of the class in individually controlling the prosecution of defense of separate actions; (B) the extent and nature of any litigation concerning the controversy already commenced by or against members of the class; (C) the desirability or undesirability of concentrating litigation of the claims in the particular forum; (D) the difficulties likely to be encountered in the management of a class action.” (Emphasis added.)
Mobil’s primary contentions focus on whether the common issues predominate over the individual issues framed by variations in applicable state law and by the individualized examination of lease formation. The predominance inquiry of Rule 23(b)(3) of the Federal Rules of Civil Procedure, which parallels K.S.A. 60-223(b)(3), tests whether proposed classes are sufficiently
cohesive to
warrant adjudication by representation, a standard “far more
*876
demanding” than the commonality requirement of Fed R. Civ. Proc. 23(a).
Amchem Products, Inc. v. Windsor,
Mobil also challenges the manageability of the action as a class aсtion. The other prong under subsection (b)(3), “[c]ommonly referred to as 'manageability,’ . . . encompasses the whole range of practical problems that may render the class action format inappropriate for a particular suit.”
Eisen v. Carlisle & Jacquelin,
District courts have substantial discretion in deciding whether to certify a case as a class action.
Dragon I,
We review the certification of a class action for an abuse of the discretion as outlined above. A trial court abuses its discretion if it fails either to evaluate carefully the legitimacy of the рlaintiffs’ allegations and evidence supporting class treatment or to conduct a rigorous analysis to determine whether the statutory prerequisites have been satisfied.

Dragon I,
Summary of Challenges to the District Court’s Class Certification
Mobil’s challenge to the district court’s class certification order is multifaceted. Mobil initially argues the district court “ignores the Kansas Supreme Court’s directives in Dragon I and Dragon II by failing to hold Plaintiffs to their burden,” by shifting that burden to Mobil and by failing to perform a rigorous analysis of the predominance and manageability elements.
More specifically, Mobil claims that the district court’s apparent application of lex fori — the law of the forum — as the choice of law is contrary to Kansas caselaw because the subject royalty interests are governed by leases executed in many states, and the application of the law of the forum is unconstitutional as “to a nationwide class’s claims.” Moreover, Mobil argues that when the proper choice-of-law doctrine of lex loci contractus is considered, a host of legal questions framed by the action will be subject to various state laws, thus demonstrating thаt common questions of law do not predominate.
Additionally, Mobil claims that a proper reading of
Smith v. Amoco Production Company,
*878 In summary and for purposes of our analysis, we address two major concerns in this appeal: (1) Did the district court abuse its discretion in failing to consider the proper choice-of-law doctrine and would application of the proper doctrine create such diversify of legal issues that statutory prerequisites for a class action would be defeated? and (2) Did the district court abuse its discretion in misconstruing controlling caselaw governing implied covenants of the oil and gas leases and would a proper construction and application of such caselaw result in a myriad of individualized factual inquiries that would inevitably defeat the statutory prerequisites fоr a class action?
Did the District Court Aruse its Discretion in Failing to Consider the Proper Choice-of-Law Doctrine for this Litigation?
Mobil contends the district court erred in addressing the choice-of-law issues raised in this case. Mobil argues that tire district court improperly applied a
lex fori
approach to resolving the conflicts issue, which it claims is inconsistent with Kansas law. Further, Mobil contends such an application of lex fori to every class member’s claim would be unconstitutional and that Kansas law requires the application of the
lex loci contractus
principle adopted by Kansas in some class actions framing contract disputes, requiring the application of the law wherе each lease was finalized. In a conflict-of-law situation, the determination of which state’s law applies is a question of law over which this court has unlimited review.
Foundation Property Investments v. CTP, 37
Kan. App. 2d 890, 894,
The district court’s findings and conclusions as to the proper choice of law included the following:
“The Kansas Supreme Court has applied Kansas Law to oil and gas leases located in Kansas, regardless of where they were executed. Phillips Petroleum Co. v. Shutts,472 U.S. 797 , 815,105 S.Ct. 2965 , 2976,86 L.Ed.2d 628 (1985) (‘Shutts II'); Shutts v. Phillips Petroleum, Co.,240 Kan. 764 , Syl. ¶ 4,732 P.2d 1286 (1987) (‘Shutts III'); Sternberger v. Marathon Oil Co.,257 Kan. 315 , 322,894 P.2d 788 (1995). This practice is consistent with established law.
*879 “3. Mobil and its royalty owners under Kansas leases have previously applied Kansas Law when resolving royalty payment disputes between them. Lightcap v. Mobil Oil Corp.,221 Kan. 448 ,562 P.2d 1 (1977); Matzen v. Cities Service Oil Co.,233 Kan. 846 .
“5. Mobil does not claim to have applied the law of any state other than Kansas when deciding how to рay its royalty owners for gas produced in Kansas.
“6. Mobil has admitted that Kansas law applies to this case.
“7. Mobil’s expert who conducted a random review of Mobil’s lease files saw no evidence among Mobil’s documents to indicate that it applied non-Kansas law to the administration of its leases.
“The Court has carefully considered Mobil’s position regarding choice of law, and finds that allowing this case to proceed as a class action will not result in the predominance of individual issues, nor render the case unmanageable.”
The District Court’s Choice-of-Law Selection
Mobil’s argument here borders on disingenuous. Although Mobil has characterized the district court’s choice of law as
lex fon,
it is clear to this court that the choice-of-law doctrine selected and applied by the district court was
lex rei sitae
— the law of the place where the property is situated. Our Supreme Court has consistently applied the law of Kansas to disputes requiring the construction and enforcement of oil and gas leases covering Kansas real estate. In
Smith,
Application of the
lex rei sitae
choice of law to resolve disputes in the construction and enforcement of oil and gas leasehold interests is not unique to Kansas. Courts in other oil and gas producing states apply
lex rei sitae
to disputes regarding the payment of royalties on oil and gas produced from leases covering acreage locаted within their boundaries. See, e.g.,
Exxon Mobil v. Ala. Dept. of Conservation,
Mobil argues that in contract cases Kansas courts have generally applied the rule of
lex loci contractus
— the law of the place where the contract was made controls. See
Dragon I,
In support of its contention that
lex loci contractus
is . the proper choice-of-law principle to apply in a case requiring the construction and enforcement of oil and gas leases, Mobil cites
Roberts v. Chesapeake Operating, Inc.,
Mobil’s reliance on these cases is not persuasive. First, while
Roberts
cited the
lex loci contractus
rule in a case where mineral estate owners sued for additional royalties on Kansas leaseholds, that language is mere dicta. After citing the leic
loci contractus
rule, the federal district court in
Roberts
noted that the parties failed to provide any facts as to where the contract was formed and both parties agreed in the pretrial order that Kansas contract law should govern; accordingly, the court did not determinе where the contract was formed and simply applied Kansas law by default.
Mobil’s reference to Sidwell also is unhelpful. Sidwell and the other cases cited by Mobil merely applied general contract principles to oil and gas leases, but none of these cases involved choice-of-law issues. Thus, they do not undermine Shutts III or Stemberger as to which choice-of-law principles apply when litigation frames issues surrounding construction and performance of oil and gas leases covering Kansas acreage.
Mobil’s citation to
Coral Production,
Indeed, Mobil admitted in answers to interrogatories that Kansas law was a driving factor in determining how it should deduct expenses in calculating royally payments — the essence of this dispute. Mobil was asked for each reason why it contended “it is entitled to take each such royalty deduction,” and it responded in part:
“Under these [different] leases and Kansas law, if the gas is not sold at the wellhead, the market value of gas at the well may be determined by deducting from the amount for which gas is sold off the leased premises the reasonable cost of getting the gas from the well to the point of sale.” (Emphasis added.)
For all these reasons, the district court did not err in holding that the doctrine of lex rei sitae governs the claims of the plaintiffs’ class and in rejecting Mobil’s contention that a proper application of lex loci contractus would defeat the prerequisites for maintenance of a class action because of the need to apply varying and disparate laws of numerous states where the instruments were executed.
Mobil’s Constitutional Challenge
Mobil’s challenge to the constitutionality of applying Kansas law here is also rather disingenuous. For a state’s substantive law to be selected in a constitutionally permissible manner, that state must have a significant contact or significant aggregation of contacts, creating state interests, such that the choice of its law is neither arbitraiy nor fundamentally unfair.
Allstate Ins. Co. v. Hague,
Mobil’s constitutional argument is fundamentally premised on the suggestion that the district court applied a lex fori approach to •a nationwide class action. The premise is false in two regards. As already discussed, we do not believe the court applied the lex fori doctrine. Moreover, this action is not a typical nationwide class action; instead, it involves only the enforcement of provisions in oil and gas leases covering Kansas realty. Application of Kansas law to such an action cannot be said to be unconstitutional.
First, we are aware of no authority holding that it is unconstitutional to apply the law where real property is located to disputes surrounding enforcement of leasе obligations. See 16 Am Jur. 2d, Conflict of Laws § 24. Although an oil and gas lease is generally classified as personalty in Kansas, see, e.g., 1 Pierce, Kansas Oil and Gas Handbook § 4.11, p. 4-15 (1991), Kansas has recognized that the rights to future royalty payments pursuant to such leases are essentially part of the lessor’s realty interests:
“The lessor’s rights to royalty do not originate with the lease. The lessor reserves his rights to royalty out of the grant. His rights arise from his ownership of the real estate rather than the lease and are therefore interests in real estate until the oil and gas are captured. It follows then that future royalty (unaccrued royalty) is a part of the real estate of the lessor; it is uncaptured and of an undetermined amount or location.” In re Estate of Sellens,7 Kan. App. 2d 48 , 51,637 P.2d 483 (1981), rev. denied230 Kan. 818 (1982).
Indeed, oil and gas leasehold interests are to be treated as real property under the statutes pertaining to recordation of instruments conveying real estate. See K.S.A. 58-2221(b);
Ingram v. In
gram,
*884 We conclude that the allegations of the plaintiffs’ сlass implicate significant contacts with Kansas and there is no arbitrariness or unfairness in the application of Kansas law in determining how the subject oil and gas leases should be construed and enforced. Mobil’s constitutional challenge to the district court’s choice of law is rejected.
Did the District Court Abuse its Discretion in Misconstruing Controlling Caselaw Governing Implied Covenants of the Oil and Gas Leases?
Mobil also argues class action certification was improper because individual issues would predominate over the common questions of law or fact. Mobil argues that to determine whether there was a breach of an implied covenant within the leases would require evaluating each of the individual leases and their various amendments, together with an individualized examination of the factual circumstances and intent of the parties at the time each of the lease instruments were executed. As argued by Mobil, the controlling caselaw means “the facts and circumstances surrounding each particular lease must be analyzed to determine if the alleged implied obligation may be inferred” and this includes the express language of the lease, other relevant writings, and “all the circumstances and conditions which confronted the parties when the contract was formed.”
The district court rejected Mobil’s contention, essentially finding that individualized examination of lease variations and circumstances surrounding lease formation was unnecessary:
“This Court does not agree with Mobil’s contention that the Plaintiffs must present evidence that the lessee and the lessor intended to require the lessee to fulfill the implied covenant to market minerals produced.
“Most of die leases in the Hugoton Gas Field were signed in the 1930’s and 1940’s. Those who executed those leases, either as a lessee or a lessor, are long dead.
“There is an implied covenant to market minerals produced under all oil and gas leases in Kansas.
“To claim that there needs to be evidence produced to prove that at the time of execution of the lease, that the parties intended the lessee to fulfill the implied covenant is an abstract absurdity.
“This Court believes Mobil misapplies the law of Smith v. Amoco, supra.
*885 “Mobil has admitted that the terms of the leases speak for themselves. When the leases were executed, if Mobil or its predecessor wished to avoid the implied covenant, they were obligated to include clear and express language to this effect in the royalty instrument itself. Gilmore v. Superior Oil,192 Kan. at 391 ,388 P.2d at 605 .
“The Court has considered Mobil’s objection based on its theory of how the implied covenant must be established in each lease and finds that its pursuit of such defense will not result in the predominance of individual issues or otherwise render the case unmanageable.
“Mobil as the lessee-producer, has treated all of its royalty owners the same way, regardless of any variations in the lease language, and that makes this proposed class a manageable class action.”
Mobil’s challenge is based solely on its reading of our Supreme Court’s opinion in
Smith v. Amoco Production Company,
No owner of a Kansas royalty interest has been required to prove a specific intent to include an implied covenant in an oil and gas lease.
Robbins,
Under Kansas law, an implied covenant can only be defeated by express language showing a contrary intent.
Christiansen v. Virginia Drilling Co.,
Mobil contends that the Supreme Court effectively overruled all of this precedent in
Smith.
The limited issue in
Smith,
however, was whether the implied covenant to market gas produced from the leasehold was implied in fact or implied in law/or
purposes of selecting the proper statute of limitations.
The court concluded the
*887
covenant was implied in fact, resulting in the application of the 5-year statute of hmitations for express contracts.
“ ‘[i]n those instances in which thе court has been called upon to determine which statute of limitations should be applied to actions on the implied covenants, it has been held that the statute governing the bringing of actions on written contracts is applicable.’ (Emphasis added.) 5 Kuntz, A Treatise on the Law of Oil and Gas § 54.3(b), pp. 9-10 (1978).” 272 Kan at 74.
Likewise, the court cited another authority, noting: “ ‘Does it make any difference whether covenants are impHed in fact or in law? Judging from the reported cases, the answer seems to be, not often and not much.’ [Citation omitted.]”
The
Smith
opinion is Hmited to holding that impHed covenants are impHed in fact for purposes of the statute of Hmitations. The opinion contains no hint that the court intended to overrule in any way prior cases which have not rеquired proof of a factual intent for impHed covenants to exist. And most importantly, if this were the case,
Smith
would have required a very different remand that may well have destroyed the prerequisites for a class action. Instead, the remand directed only a finding on whether the impHed covenants were breached.
A federal court of appeals long ago in a very celebrated and still viable case applying Kansas law suggested that impHed covenants within oil and gas leases are not so much a function of intent but rather of the obHgation inherent in the language of the contract:
“Implication is but another name for intention, and if it arises from the language of the contract when considered in its entirety, and is not gathered from the mere expectations of one or both of the parties, it is controlling.” Brewster v. Lanyon Zinc Co.,140 F. 801 , 809 (8th Cir. 1905) (noted for its “continued vitality” in 5 Williams & Meyers, Oil and Gas Law, §§ 802, 806 [2009]).
Treatise law is in agreement — specific intentions of the parties to an oil and gas lease are of no legal moment to the existence of covenants impHed from the express language of the contract:
*888 “When it comes to the application of an implied covenant to a particular dispute, courts may move some distance away from the fact of parties’ intention and closer to the law as an instrument for enforcing ethical norms. Thus when the lessor sues the lessee for his [or her] failure to use sandfracing to increase production, he may claim as a fact that he expected diligent efforts to be made to maximize production, but he can hardly claim that he expected the use of sandfracing when the lease antedated the invention of the process.” 5 Williams & Meyers, Oil and Gas Law § 803, p. 24.
Indeed, one need not examine parole evidence, surrounding circumstances, or extant industry practice to determine whether such covenants should be implied. This has simply never been the law or practice in Kansas.
Thus, Mobil’s contentions appear to read far too much into the
Smith
opinion. No direct language in
Smith
indicates that the implied covenants which have been read into oil and gas leases for years are hereafter to be proven to be within the subjective intent of the parties at the times the leases were entered into. As before, implied covenants are essentially presumed to be the intent of both parties and need not be proven by reviewing the specific intent of the executing parties; individualized proof of intent has never been required. We do not see that
Smith
intended to change this practice when its focus was solely on the statute of limitations issue. And most importantly, had the court been interested in an examination of individualized lease variаtions and circumstances surrounding formation, the remand would have been far different than ordered. See
Mobil’s suggestion that such an individualized examination defeats the prerequisites for class action has been characterized as the
de rigeur
defense of such class actions and rejected by most courts. See McArthur,
A Minority of OneP The Reasons to Reject the Texas Supreme Court's Recent Abandonment of the Duty to Market in Market-Value Leases,
37 Tex. Tech. L.R. 271 (Winter 2005). With Texas notably the stand-out nonconformist jurisdiction, most courts have rejected this defense when faced with remarkably similar facts. See,
e.g., Duhe v. Texaco, Inc.,
We align our court with those of Louisiana, North Dakota, and Oklahoma in holding that in a purported class action claiming improper calculation of royalties, there is no need to examine individual lease formation and the intent of the parties thereto for purposes of determining predominance of common issues or manageability in certification proceedings where there has been shown a systemic common course of conduct by an oil and gas lessee in calculating royalties payable. We agree with the district court and its rationale in rejecting Mobil’s argument that a need for individualized examination of lease formation and language defeats predominance of common issues or otherwise renders this case unmanageable as a class action.
Having so held, we are not suggesting that all purported class members can be treated idеntically. Although Mobil does not seem to rely on the obvious major categories of potential class members in challenging the district court’s certification order, it was noted by the district court and it appears to this court that those for whom a 1984 settlement is applicable will likely need to be treated differently than those for whom the settlement is not applicable. Moreover, the record reflects that among the leases at issue, some were executed or amended recently to expressly abrogate the implied covenant that underlies the plaintiffs’ class allegations. These and other easily defined categories of pоtential plaintiffs, however, need not bar initial class certification.
Class action certification is discretionary with the trial court.
Anderson v. City of Albuquerque,
In summary, we conclude the district court rigorously analyzed whether the prerequisites of the statute were satisfied. Especially with regard to the two areas challenged on appeal, the district court took the proper factors into account in the proper way and made a decision within the legal applicable legal standards to certify the class action. There was no abuse of discretion in the selection of choice of law principles or in rejecting an individualized examination of the circumstances surrounding each of the leases in order to determine whether implied covenants were intended. It is the judgment of this court that the district court performed a particularly comprehensive review of the statutory prerequisites, gave consideration to Mobil’s views on predominance and manageability, entered findings supported by the evidence, and made conclusions of law that were entirely sound and fully explained in the final journal entry of judgment.
Affirmed.
