LAVENDER, Justice:
This appeal arises from a grant of summary judgment in favor of Appellee, Panhandle Eastern Pipe Line Company, one of three defendants sued by Appellants, a group of working interest owners in the Yowell No. 1-26 natural gas well located in Roger Mills County. Panhandle is an interstate pipeline company that purchases natural gas and transports it through a pipeline system in interstate commerce. Other defendants in the trial court were El Paso Natural Gas Company and Dyco Petroleum
Corporation.
Appellants alleged in their petition that Panhandle and El Paso were purchasing natural gas from the Yowell No. 1-26 well from Dyco (alleged to be the owner of approximately 47% of the working interest) and other working interest owners. The gist of Appellant’s three causes of action was that they are entitled to be paid in proportion to their respective working interests in the well for the gas purchased by Panhandle and El Paso, but that none of the defendants paid them. The first cause alleged by Appellants sounded in tort for conversion of their respective proportionate share of gas. The second was for violation of certain Oklahoma statutes referred to by the parties as “ratable” take statutes. Appellants assert such provisions require Panhandle and El Paso to take gas from all working interest owners in proportion to their respective interests and pay for it accordingly.
The third cause was brought pursuant to 52 O.S. Supp.1983, §§ 541-547 which would allow working interest owners in a well the opportunity to ratify any agreement to sell gas entered into by another working interest owner and a purchaser under certain guidelines and to be paid in proportion to their interest. Appellants asserted that Dyco would not allow them to ratify the agreements it and other working interest owners had with El Paso and Panhandle and that none of the defendants had paid them in proportion to their interests in the well.
. After filing an answer to the petition Panhandle submitted a motion for summary judgment arguing the trial court lacked subject matter jurisdiction over the causes of action. It took the position that neither the legislative
or judicial
power of the State of Oklahoma could be invoked, whether by statute, Oklahoma Corporation Commission regulation
or court action,
to require an interstate pipeline company to purchase gas from any particular producer because via the Supremacy Clause to the United States Constitution (U.S. CONST, art VI, cl. 2) all such state authority was preempted by the operation of two related federal statutory schemes, the Natural Gas Act, 15 U.S.C. §§ 717 et seq. and the Natural Gas Policy Act, 15 U.S.C. §§ 3301 et seq. In essence, Panhandle argues the United States Constitution would be violated if Appellants were allowed to recover under either their conversion or statutory claims and to the extent the state statutes relied on by Appellants provide a viable
avenue under state law to allow such a result they are unconstitutional.
Submitted with Panhandle’s motion was an affidavit from their in-house counsel. The affidavit set forth its position as a natural gas company and owner/operator of a pipeline system that purchases gas from producers, transports it in interstate commerce and sells it to various concerns along the pipeline. The affidavit indicated that any requirement to purchase uncommitted interests in wells connected to its pipelines would affect the overall price mix of all gas it purchased. It argued that because it was under certain contractual obligations, commonly referred to as “take or pay”, to either accept delivery of contract quantities of gas from producers or pay producers for any deficiency in receipt of deliveries below the contract quantities, if it was required to purchase additional gas from working interest owners in positions like Appellants (i.e. those without contracts with Panhandle) or to pay them in proportion to their working interests for gas purchased under these contracts, these “take or pay” provisions might be activated because additional gas was not needed to supply the demand of its customers.
In support of its preemption argument Panhandle places heavy reliance on two United States Supreme Court cases it says are dispositive of the instant controversy. These cases are
Northern Natural Gas Co. v. State Corporation Commission of Kansas,
372 U.S. 84, 83 S.Ct. 646, 9 L.Ed.2d 601 (1963) and
Transcontinental Gas Pipe Line Corp. v. State Oil and Gas Board of Mississippi,
474 U.S. 409, 106 S.Ct. 709, 88 L.Ed.2d 732 (1986). The two cases held that state regulations requiring interstate purchasers like Panhandle to take or purchase gas ratably from producers are preempted by federal regulatory power over interstate pipelines’ costs and purchasing patterns exercised by the Federal Energy Regulatory Commission or FERC.
Northern Natural
was decided under the provisions of the Natural Gas Act of 1938 which empowered the Federal Power Commission (FERC’s predecessor) to set price ceilings for sales from producers to pipelines and to regulate the prices pipelines could charge their downstream customers.
Transcontinental
involved a determination of whether the ruling of
Northern Natural
survived passage of the Natural Gas Policy Act of 1978 which removed some of the federal controls contained in the Natural Gas Act and to a greater extent left the field of buying and selling natural gas to the market forces of supply and demand.
In the present case Panhandle argues that to subject it to lawsuits and potential liability, either monetary or in the form of requiring it to purchase gas from producers with which it has no contractual obligation, puts it in the same situation as that of the pipeline companies involved in
Northern Natural
and
Transcontinental
and, thus, Appellants’ causes of action are likewise preempted. The trial court agreed and granted summary judgment in favor of Panhandle on the basis it lacked subject matter jurisdiction over the causes of action as they were preempted by these federal Acts and the
force of the Supremacy Clause to the United States Constitution.
We have determined that it would be improper for us to reach any of the constitutional issues raised by the parties because a ruling on any such issue is unnecessary to properly resolve the merits of this controversy.
This is so for the reason the record discloses Appellants have no claim against Panhandle as alleged in their first cause of action under the common law of the State of Oklahoma. As well, Appellants have no viable claim under the “ratable” take statutes relied on because those statutes that do apply to regulate gas purchasing do not apply to mandate nondiscrimination on the part of natural gas purchasers in relation to their purchasing practices between working interest owners in a single well, but only to situations where multiple wells are involved in a common source of supply or between sources of supply. In addition, other statutes relied on do not apply to purchasing practices at all, but only to the transportation of natural gas or its production. Finally, although 52 O.S.Supp.1983, §§ 541-547 is applicable to situations involving a single well, Appellants have abandoned or waived error in regard to the trial court’s ruling in relation to that statutory scheme because they have failed to present any argument or authority in their briefs submitted to this Court based on said provisions.
OKLAHOMA LAW DOES NOT RECOGNIZE A CLAIM FOR CONVERSION ON THE FACTS REVEALED BY THE INSTANT RECORD
In relation to Panhandle’s motion for summary judgment, the record in this case reveals that Appellants, along with Dyeo and others, own various percentages of the working interest in the Yowell No. 1-26 natural gas well. It also reveals Panhandle has been purchasing gas from the well from Dyco and other working interest owners and paying these working interest owners for the gas purchased, while Appellants have not received any of the proceeds from the sales. Appellants allege such in their petition and these allegations are confirmed in the affidavit of one of Appellants which was submitted to the trial court in response to Panhandle’s motion for summary judgment. The record further reveals Appellants are not parties to the agreement Dyco has with Panhandle for the sale of natural gas. This is confirmed by Appellants petition and the same affidavit by the assertion that Dyeo refuses to allow them to ratify its agreement with either Panhandle and/or El Paso. It is our view that as to the above material facts there is no genuine dispute and Panhandle was and is entitled to judgment in its favor as a matter of law. As will be explained, in these circumstances, Oklahoma law provides no tortious action for conversion in favor of working interest owners like Appellants against a purchaser of natural gas who buys gas from one or more other working interest owners in the same well.
Under Oklahoma law Appellants and the other working interest owners in the well are tenants in common.
As coten-ants each is entitled to market production from the well and the sale of gas to a purchaser by one or more cotenants without consent of other cotenants is lawful. Under ordinary circumstances it does not involve tortious conduct, i.e, conversion, on the part of either the purchaser or on the part of the working interest seller because
each cotenant has the right to develop the property and market production under the common law.
Recently in
Teel v. Public Service Company of
Oklahoma,
this Court outlined the limited circumstances under which a purchaser may be liable for conversion when purchasing natural gas from a well operator. This situation initially arises when the cotenants name another cotenant to exploit the cotenancy for their mutual profit by entering into an operating agreement amongst themselves to have the operator market or sell gas produced from the well.
It also requires that there be an absence of a division order.
Additionally, and most importantly for purposes of disposition of the instant case,
a purchaser must have notice that a working interest owner not a party to the division order has revoked the operator’s right to sell his/her share of gas under the operating agreement and the purchaser must continue to treat the situation as if it is purchasing the nonconsenting cotenant’s share of gas, while failing to account to each working interest owner for his/her pro rata share of the proceeds.
The
Teel
situation only comes into play when a purchaser purports to buy gas of an owner from an operator which is not authorized to deliver it.
Our situation is virtually the opposite of that faced in
Teel.
In
Teel
the working interest owner, by revoking the operating agreement, expressed an intent not to have the operator sell or the purchasers buy his gas. The purchasers, contrary to such intention, continued to treat the situation after revocation as if they were still purchasing gas from a working interest owner
that did not want to sell it to them.
In contrast Appellants here take the position that anytime one cotenant sells gas to a purchaser, which as noted above the cotenant has a lawful right to do, the purchaser becomes liable to each and every other working interest owner for conversion simply by the force of the working interest owner’s
desire to sell his gas and be paid in proportion to his percentage of working interest in the well, even though not a party to any purchase contract.
We find no authority for this result under the common law of Oklahoma and we reiterate the admonition in
Teel
itself contained in the first footnote thereof, that, “[¡Insofar as
Teel
announces a rule of conversion, it is confined to the pecular scenario found [therein].”
Further, as Teel notes, “[a] gas sales contract executed by a cotenant is limited to his/her interest”
and we see "nothing in the facts of this case that would indicate gas purchased by Panhandle under agreement with Dyco, on behalf of itself or itself and some of the other working interest owners, would constitute either a wrongful sale or purchase of Appellants’ interest as was the case in
Teel.
Therefore, on the instant record Appellants h,ave no claim against Panhandle for conversion of their respective percentages of working interest in the Yowell No. 1-26 natural gas well.
Such a disposition does not leave working interest owners like Appellants without a remedy. The law has been settled for some time that a producing coten-ant must account to a non-producing coten-ant for the market value of the production less any reasonable and necessary expenses of developing, extracting and marketing.
Further, certain practices of the industry have been acknowledged by the courts to remedy situations like that apparently existent here where only certain working interest owners have sold production. These practices involve balancing in kind the production from the well by allowing cotenants like Appellants the opportunity to market gas from the well (i.e. taking a certain percentage of an overproduced party’s gas until any imbalance in the co-tenant’s takes from the well are made up), by periodic cash balancing whereby under-produced cotenants receive cash from producing cotenants in proportion to their respective interests and cash balancing upon any particular gas reservoir’s depletion.
Instead of bringing an action for accounting or relying on one of the potential solutions set forth above, Appellants sought instead to turn what should have been largely an equitable proceeding into a tor-tious one not sanctioned by Oklahoma law. Accordingly, although not for the reason of federal preemption relied on by the trial court, we affirm the grant of summary judgment in favor of Panhandle because Appellants have no cause of action for conversion against it under the material facts revealed by the record.
THE STATUTES RELIED ON BY APPELLANTS TO SHOW PANHANDLE IS REQUIRED TO PURCHASE GAS IN PROPORTION TO EACH OWNERS INTEREST EITHER DO NOT APPLY TO SITUATIONS INVOLVING ONE WELL OR TO PURCHASING AT ALL BUT TO TRANSPORTATION OR PRODUCTION OF GAS
In their second cause Appellants assert certain Oklahoma statutes require Panhandle to take gas from the involved well ratably, a term they assert means, in proportion to each working interest owner’s respective ownership interest. The first statute relied on by Appellants is 52 O.S. 1981, § 23.
Section 23, in relevant part,
makes pipeline companies engaged in the business of purchasing gas common purchasers and requires them to purchase all gas offered for sale in the vicinity of or that may reasonably be reached by its gathering lines without discrimination in favor of one producer or person over another and that if a purchaser is unable to do so it must purchase from each person or producer ratably, in proportion to the average production. It also provides that a purchaser cannot discriminate in favor of its own production or production in which it is interested, directly or indirectly, in whole or in part. Another provision relied on is 52 O.S.1981, § 24.
Section 24 makes pipeline companies common carriers and prohibits unlawful discrimination in favor of the carriage, transportation or delivery of any natural gas offered to it, in its possession or control, or in which it may be interested, directly or indirectly. Both of these provisions are a part of the Production and Transportation Act of 1913 which is found at 52 O.S.1981, § 21 et seq., as amended. Another provision added to the Oklahoma statutes in 1978 and relied on by Appellants is 52 O.S.1981, § 24.1.
It provides anyone aggrieved by a common carrier’s refusal to purchase or transport gas may file a complaint with the Oklahoma Corporation Commission (OCC) and that OCC has authority to order purchase or transport, including the fixing of a fair rate for any transportation.
The next provision relied on is 52 O.S. 1981, § 233,
a part of an act passed in 1913 for the express purpose of defining
ownership in gas and restricting the output thereof. Such act is found at 52 O.S.1981, §§ 231-235.
Section 233, with certain exceptions, requires anyone taking gas from a gas field to take ratably from each owner of the gas in proportion to his interest, upon such terms as may be agreed on by the owner and the party taking the gas. It further provides if the parties cannot agree to terms OCC may fix a price for the gas and other terms of the taking after notice and hearing.
The final provisions relied on are 52 O.S. 1981, §§ 239-240
two sections of the Oklahoma Natural Gas Act of 1915 found at 52 O.S.1981, §§ 236-247. Section 239 provides when full production from any common source of supply of natural gas in Oklahoma is in excess of market demand any person having the right to drill into and produce from any common source of supply may take from the source of supply only the proportion of natural gas that may be marketed without waste, as the natural flow of the well or wells owned or controlled by such person bears to the total natural flow of the common source of supply having due regard to the acreage drained by each well. It also gives OCC
power to promulgate regulations for determination of the natural flow of any such well or wells and to regulate the taking of natural gas from all common sources of supply in the State to prevent waste, to protect the public, to protect all having a right to produce and to prevent unreasonable discrimination in favor of one common source of supply against another.
Section 240 finally provides that anyone in the business of purchasing or selling natural gas in this State is a common purchaser and must purchase all the natural gas that may reasonably be reached by its trunk or gathering lines without discrimination in favor of one producer as against another or in favor of one common source of supply against another. It further provides if such a purchaser is unable to purchase all such gas it must purchase from each producer ratably, that it cannot discriminate in favor of its own production or production it is directly or indirectly interested, but for the purpose of prorating the natural gas to be marketed such production shall be taken only in the ratable proportion that such production bears to the total production available for marketing.
Initially, we note the primary goal of statutory construction is to ascertain the intent of the Legislature.
We also note that legislative enactments concerning the same subject matter should be construed together as a harmonious whole in order to give effect to each.
In the case of
Seal v. Corporation Commission,
which involved a challenge to the constitutionality of 52 O.S.Supp.1983, §§ 541-547, we had occasion to discuss said Act and its differences with earlier provisions in the area of natural gas law in Oklahoma, including the exact statutes relied on by Appellants.
One of the main differences we recognized was that the new enactment applied to co-owners in a single well as opposed to owners of interests between wells in a common source of supply.
This view was consistent with the manner in which the provisions relied on by Appellants had historically been interpreted. For example, in
Republic Natural Gas Company v.
State,
we utilized the statutory definition of the term ratable taking found at 52 O.S.1941, § 232 in affirming an order of OCC based on § 233 to the effect that one gas company had to either take gas ratably from another gas company’s well or cease production from its own wells in a common source of supply. Section 232, of course, is part of the same Act which contains § 233. The definition utilized is as follows:
[Rjatable taking is defined as the proportion which the natural flow of gas from the wells of one producer bears to the amount of the natural flow from the wells of the owners producing from the same common source of supply or common reservoir.
This definition does not and we conclude was never intended by the Legislature to reach situations involving purchasing pat
terns by purchasers of working interest owners’ various percentages of ownership interest in a single well. Another provision of the Act is also inconsistent with a view which would apply the provisions of § 233 to a dispute involving gas purchasing patterns from a single well. 52 O.S.1981, § 234, in providing liability for damages and penalties for misappropriation of gas says anyone, “[T]aking more than his ... proportionate share of ... gas, in violation of the provisions of this act, shall be liable
to any adjoining well owner
.....” Thus, it can be seen, both by the language utilized in the Act itself and by judicial interpretation of that language, the provisions of § 233 apply to owners of interest between wells in a common source of supply and not to purchasing patterns among co-owners in a single well.
The same basic analysis applies to the statutory scheme we have referred to as the Natural Gas Act of 1915 [52 O.S.1981, §§ 236-247], Section 239 of this Act contains substantially the same definition as that found in § 232 in regard to taking gas from a common source of supply and we noted in
Republic
that said provision, “[V]ested in [OCC] power to enforce ratable taking under the provisions of § 233....”
Thus, when § 240 of the Act refers to purchasers such as Panhandle, “purchas[ing] natural gas from each producer ratably” or in regard to its own production, or production it may be interested directly or indirectly, that said production shall be taken “[I]n the ratable proportion that such production bears to the total production available for marketing,” we conclude the Legislature only intended proration of purchases between the various wells in a common source of supply or purchasing patterns between common sources of supply.
Furthermore, § 239 by its express language does not apply to the
purchase
of gas, but to the production thereof and said provision places no duty on an entity that is strictly a purchaser. By its very terms it concerns those, “[H]aving the right to drill into and produce gas from any ... common source of supply_”
We find no support for the proposition that § 239, standing alone, would require a purchaser, rather than a producer to comply with its terms.
As to § 23 we also conclude said provision was never intended to mandate that a purchaser such as Panhandle purchase gas from a single well from all having an ownership interest in the well. We so indicated in
Seal v. Corporation Commission, supra
and we see no need at this time to retreat from such view. Such a view is consistent with previous cases either discussing or interpreting § 23 which have concerned situations involving multiple wells or entire gas fields.
Although the Oklahoma Legislature has promulgated provisions in regard to working interest owners that may limit their individualized ability to drill into a common source of supply by affording power to OCC to create drilling and spacing units and the power, when they cannot voluntarily agree, to order forced pooling of their interests and, thus, the sharing of costs and production from a producing well,
we conclude neither such provisions or the statutes relied on by Appellants in their second cause of action mandate that a purchaser such as Panhandle either take their proportionate share of gas from the involved well or pay them in proportion to their respective ownership interests therein.
We are further of the view that § 24 by its plain and unambiguous language does not apply to require a gas purchaser such as Panhandle to purchase gas from the involved well. That statute is concerned with the carriage or transportation of natural gas and prohibits discrimination in such regard. Thus, even if it could be said that it applies to situations involving a single well, we conclude it would do no more than require a pipeline company to transport Appellants’ gas to a willing buyer should they have one. Appellants’ case is not one where they seek to have Panhandle transport their gas to a willing purchaser. They instead seek to have Panhandle purchase their gas. Although a company such as Panhandle may at the same time be both a common purchaser of gas under § 23 and a common carrier under § 24, we find no support for the proposition that all pipeline companies necessarily
must
be both common carriers
and
common purchasers. We recognized as much in
Inexco Oil Co. v. Corporation
Commission,
a case construing §§ 23, 24 and 24.1, when we observed, “[A] corporation simultaneously may be a common purchaser and a common carrier.” At a minimum, for a pipeline company to be a common purchaser under § 23 it must engage in the business of purchasing natural gas, as opposed to the mere carriage thereof. Therefore, § 24 provides Appellants no vehicle for recovery because that provision does not apply to afford the form of relief they seek in regard to their second cause of action.
The final section relied on by Appellants in support of their second cause is § 24.1. Although in
Inexco
we seemed to interpret § 24.1 as applying only to the transport of natural gas
we note that said provision also appears to impliedly mandate a company that would solely be characterized as a common carrier to purchase natural gas. We believe to the extent § 24.1 talks about the purchase of natural gas such language must be read in context with the preceding sections contained in the original 1913 Act, i.e. §§ 23-24. Read in such context it becomes evident § 24.1 does not mandate that an entity solely classified a common carrier is required to purchase gas, in addition to the transport thereof. Likewise, to the extent § 24.1 does require the purchase of gas we conclude such mandate is only in regard to those entities that would be classified common purchasers Under § 23 and that any such mandated purchases do not apply to situations like the one at hand because as noted in
Seal
that statute applies to owners of interests between wells in a common source of supply, as opposed to interests of co-owners in a single well.
In that none of the provisions relied on by Appellants to support their second cause are applicable to give them a viable claim in light of the facts contained in the record, we affirm the ruling of the trial court for the reasons set forth above. As with our determination on Appellants’ conversion claim our disposition does not require us to rule on the preemption question.
APPELLANTS HAVE WAIVED ANY CLAIM OF ERROR IN RELATION TO THE TRIAL COURT’S DISPOSITION OF THEIR THIRD CAUSE OF ACTION
When one comes before this Court challenging the determination of a trial court they are duty bound to set forth argument and authority supporting a claim of error as to the trial court’s ruling.
Furthermore, a long-standing principle of this Court is that, “[assignments of error which are not argued in the brief with citations of authority will be considered and treated as waived by this Court.”
In the present appeal Appellants have totally failed to present any argument or any authority concerning the trial court’s disposition of their third cause of action and for this reason we conclude they have waived any claim of error in regard thereto.
Appellants have presented two substantive appellate briefs to this Court, a brief in chief and a reply brief. In these submissions nowhere do Appellants expressly discuss that their trial court petition contained a third cause of action based on 52 O.S. Supp.1983, §§ 541-547. No discussion, at all, is set forth in either of the briefs concerning said statutory scheme. In fact, neither of the briefs contain one citation to these statutes. We, thus, have no occasion to construe §§ 541-547 in relation to the trial court’s determination that Appellants’ third cause against Panhandle, based on said provisions, was preempted by federal law because Appellants have waived error as to said ruling. Accordingly, the decision of the trial court is affirmed for the reasons and in conformity with the views expressed in this opinion.
All the Justices concur.
