delivered the opinion of the court:
This is an action in equity for the cancellation of oil leases for failure to develop and produce oil on the properties. The complaint was in three counts each involving a separate tract owned and leased by plaintiffs to defendant in 1936. Upon hearing, the circuit court of Wayne County entered a decree for the defendant as to counts 1 and 3. As to count 2, the court entered an alternate decree that unless the defendant should commence to drill a well on the east 10 acres of the tract within 60 days from the date of the decree, and drill the same with reasonable diligence to completion to test the Rosiclare formation, the lease would be cancelled as to the said east 10 acres. From this portion of the decree, the defendant appeals.
Tract No. 2 involved in count 2 is located in Wayne County and consists of 20 acres which was leased to defendant by plaintiffs in 1936. In 1945 the defendant drilled three wells in the immediate area to the Rosiclare formation. One well was drilled in the middle of the west 10 acres of plaintiffs’ 20-acre tract. This well produced 5589 barrels of oil until 1948 when it was plugged. Defendant then drilled in the same location to the Aux Vases formation which produced 32,371 barrels from 1948 to 1953. In 1953 defendant resumed pumping from both Rosiclare and Aux Vases formations, which resulted in a combined production of 5977 barrels through 1955.
Defendant in 1945 also drilled a well to the Rosiclare formation on the Ruble tract, offsetting the east 10 acres of plaintiffs’ tract. This well produced 201,717 barrels until it was plugged in 1952. Defendant also, in 1945, offset plaintiffs’ east 10 acres by drilling a well on the Barth tract immediately south of the east 10 acres of the plaintiffs. This well produced 191,685 barrels from the Rosiclare formation up to the time of trial. There is further evidence that in 1954 the National Associated Petroleum Company drilled two wells to the Aux Vases formation on the Ruble tract immediately to the east of plaintiffs’ east 10 acres, which wells are still producing. The evidence also establishes the drilling of offset wells on the Duke tract immediately to the north of the plaintiffs’ east 10 acres.
Defendant introduced the testimony of one Finley, a geologist employed by the defendant, who had studied the subsurface structures underlying plaintiffs’ land. This witness testified from various exhibits showing the substructure of the area involved. It would unduly lengthen this opinion to fully discuss all of the geological aspects of his testimony. From his studies and tests he determined that there would be no commercial production from the Aux Vases, the McClosky, the St. Genevieve or the O’Hara formation in the east 10 acres of plaintiffs’ tract No. 2. We find in the record no substantial contradiction of these opinions of the witness, nor do we find that they are disputed in argument.
However, this witness’s testimony was not so clear in regard to the oil production from the Rosiclare formation. He testified that the well on the west 10 acres of the plaintiffs’ tract was not commercially good from the Rosiclare formation, but that all of the oil would eventually be recovered through the existing wells in the general area. He did admit that it was possible that oil could be recovered from an additional well and that possibly not all the oil could be recovered from the tract through the well drilled on plaintiffs’ west 10 acres.
Defendant’s exhibit 5, discussed by witness Finley, showed the Rosiclare lime porosity in the general location. From that exhibit it appears that the porosity of the east 10 acres of plaintiffs’ tract is superior to that of the west 10 acres where the well was drilled. This fact would tend to endow said east 10 acres with greater commercial possibilities. Finley further testified that there was a water movement that he thought would eventually bring oil in the Rosiclare formation to plaintiffs’ tract No. 2. However we note that such a water movement or encroachment is from the east and would first hit the east 10 acres of plaintiffs’ tract. Finley testified that in 1952 at the request of the plaintiffs, he examined the possibilities of further drilling; that he concluded that such drilling would not be commercially feasible, partly for the reason that the defendant already had two producing Rosiclare wells on adjacent tracts.
It is plaintiffs’ contention that the proof of production of large quantities of oil from offset wells on adjacent premises, and the refusal of defendant to protect against drainage establishes a prima facie case in favor of cancellation. They contend that when oil has been discovered on lands, it is the duty of the defendant, express or implied, to reasonably develop the premises; and that when there are wells on such lands which produce oil to a commercial extent it is the duty of defendant to protect the leased premises against drainage, particularly when the offset wells are those of the same defendant.
Defendant contends that the burden is upon the plaintiffs to establish that the defendant failed to do what a reasonable and prudent operator would do in developing and producing the lease. They argue that there is no evidence in the record to sustain this burden of proof. They further contend that the drilling of another well on the east half of tract No. 2 would be in violation of the rules and regulations of the Illinois Department of Mines and Minerals; that the evidence in the record shows that a new well would not be commercially feasible; and that if the plaintiffs have been injured at all, they have an adequate remedy at law. Defendant also raises the defenses of laches and estoppel.
We feel that the evidence in the record sufficiently proves a prima facie case for the plaintiffs. It establishes that defendant has had two very profitable wells under lease, which offset the plaintiffs’ tract No. 2, and which have drawn substantial quantities of oil from the Rosiclare formation, one of which is still producing; that a water encroachment exists to the east of plaintiffs’ tract No. 2 which is moving westward and will bring oil to the Rosiclare formation on the east 10 acres and ultimately to the west 10 acres of tract No. 2; that in 1936 one well was drilled on plaintiffs’ tract No. 2 and no further wells have been drilled thereon; and that it is reasonable to believe that there is oil in commercial quantities in the Rosiclare formation under plaintiffs’ land. The defendant possessed technical information concerning the oil underlying the land in this area, and, within human limitations, knew the capacity of this land to produce oil. It was in control of the premises and had the right to drill. The defendant, not the plaintiffs, was in the position to know whether or not further commercial development of this acreage was practicable. We feel that this case comes clearly within the theory of the rule we announced in Stoddard v. Illinois Improvement Ballast Co.
In order to defeat the plaintiffs’ prima facie case, the burden of proceeding with the evidence devolved upon the defendant. It became incumbent on the defendant to show that the premises could not be developed for oil with profit, or that some other reason existed which should relieve the defendant from proceeding with the development of the oil lands. (Daughetee v. Ohio Oil Co.
An oil lease primarily contemplates production and a royalty consideration. Consequently we have held that there is implied under the terms of such lease an obligation on the part of the lessee to use reasonable diligence to develop the demised premises so long as the enterprise could be carried on at a profit. The lessee is not the sole or controlling arbiter of the extent to which operations should be carried, and the express or implied covenants of the lease should be construed by the standards of what is reasonable, considering the duty of both lessee and lessor. Ohio Oil Co. v. Reichert,
We turn next to the question of whether all the evidence in the record shows that defendant did use diligence and exercise reasonable judgment in failing to further develop tract No. 2. Upon an analysis of the evidence in the record, we feel it is clear that there was no duty on the defendant to attempt to produce oil from the Aux Vases formation or the O’Hara, McClosky, or St. Genevieve formations. However, the evidence in the record reasonably indicates oil in commercial quantities in the Rosiclare formation underneath the land of the plaintiffs. It therefore becomes necessary to examine the reasons why the defendant failed to develop this formation. Defendant here relies strongly upon a rule and regulation of the Department of Mines and Minerals of the State of Illinois (Rule IV(1) (A) (1) (b).). This rule provides that there shall be a minimum of 20 acres of surface area to a well drilled or deepened for production of oil from a limestone formation. It is conceded that the Rosiclare formation is a limestone formation. This defense was not pleaded by the defendant but was introduced in evidence over objection by witness Finley who testified that he knew of such rule and that the defendant observed it. It does not appear, however, that this point was argued in the trial court and it is clear from Finley’s testimony that the decision to refuse to drill on the east 10 acres of plaintiffs’ tract was not based upon this limitation. From the state of the pleadings and the record, it cannot be determined whether a permit could have been obtained to drill this well; nor does it appear that a permit would not have been obtained automatically by capping the nonproductive Rosiclare well on the west 10 acres of plaintiffs’ tract. The record indicates that this defense was an afterthought and had nothing to do with the exercise of discretion by defendant. This defense must fail for the further reason that it was not pleaded or argued below. Bryant v. Lakeside Galleries Inc.
The only other reason for the failure to drill a well into the Rosiclare formation on the east 10 acres of plaintiffs’ tract was that most of the oil in the Rosiclare formation could be drained from the area by the combined wells which the defendant had drilled under its various leases. These include the small production well on the west 10 acres, and the two highly profitable Rosiclare wells on the Ruble and Barth tracts. The plaintiffs’ evidence, the defendant’s exhibit 5, and the testimony of Finley furnished a reasonable basis for concluding that a Rosiclare well on the east 10 acres would be commercially profitable. The trial court saw and heard the witnesses testify.
The decree of a chancellor will not be reversed unless it is palpably contrary to the weight of the evidence. We believe that the evidence in the record sustained the chancellor’s judgment in determining that defendant had violated the implied duty to develop the premises and protect from drainage. Evangeloff v. Evangeloff,
Defendant next contends that regardless of any breach in the implied covenant to develop, that forfeiture is not the proper remedy. In support of that contention, defendant relies on Poe v. Ulrey,
We further distinguished the case of Poe v. Ulrey in the recent case of Hughes v. Ford,
We hold forfeiture of the lease to be a proper remedy in this case. Equity was evolved to escape the technicalities and rigidity of the common law. (30 C.J.S., par. 12, page 331; 19 Am. Jur., par. 460, page 318.) We decline to become so involved in the theories of actions and remedies as to render this court impotent to deal with the problem before it.
Defendant further argues that plaintiffs are estopped in this case by the fact that they accepted royalty division checks and signed a division order in 1951. Defendant cites no authority for this proposition except Corey v. Sunburst Oil Co.
Nor do we see any merit in defendant’s claim of laches. Laches is only available as a defense in an equitable proceeding when, by delay or neglect to assert a right, the adverse party is lulled into doing that which he would not have done, or omitting to do that which he would have done, with reference to the property had the right been promptly asserted. (Gaffney v. Harmon,
On the record in this case, it appears that the decree of the chancellor is amply supported by the evidence and it will not be disturbed. The decree of the trial court is accordingly affirmed.
Decree affirmed.
