In 3A Summers on Oil and Gas, perm. ed., § 589, pp. 109-127, and 1962 Cumulative Pocket Part, § 589, pp. 9-12, a comprehensive discourse with citation of supporting authorities may be found on the duty of the lessee under different provisions of various leases including how royalty payments are to be made, how the gas is to be measured by meter, and what price the lessee is to pay for such gas, and further, that where a lease provides for a royalty for gas, which may be paid in a number of ways (p. 113), in the absence of an express provision of the lease creating such duty, the lessee is under an implied obligation to exercise reasonable diligence in marketing the gas produced. If a market value for the gas produced does not actually exist, the basis of the reasonable value thereof may be established by competent evidence, (p. 114.)
The record discloses the gas here involved was put into pipelines already existing on the leases in question and we, therefore, need not consider that the lessee was put to any great expense in building miles of pipelines for that purpose.
Our attention has been called to Merrill on Covenants Implied in Oil and Gas Leases, 2d ed., § 85, p. 214, where the author makes the unqualified statement that,
“If it is the lessee’s obligation to market the product, it seems necessarily to follow that his is the task also to prepare it for market, if it is unmerchantable in its natural form. No part of the costs of marketing or of preparation for sale is chargeable to the lessor. This is supported by the general current of authority." (pp. 214, 215.)
In the 1959 Pocket Supplement to the above work, § 85, p. 61, we find the most recent authorities on the subject of the duty to prepare for market and what is necessary in such preparation, and finally, that the lessee is required to bear the expense because such preparation is necessary to make the gas marketable.
Plaintiffs, in an effort to set up an enlargement of the duty of the lessee, call our attention to the two oil and gas division orders sent to them by the lessee. However, we are inclined to agree with the trial court and the defendant that consideration of such division orders is not necessary to a determination of this case, and we shall, therefore, not discuss them.
Other authorities cited and discussed by the parties are recognized but we fail to see how they may be applicable in this case. It is admitted by everyone concerned this is a novel question in our oil and gas industry, and while the law is not a static thing, and especially is this true of the law of oil and gas, we are of the
