The Fourth Court of Appeals in San Antonio handed down an opinion this week in Adams v. Murphy Exploration & Production Co.-USA, deciding the meaning of “offset well” as used in an oil and gas lease.
The plaintiffs in the case signed an oil and gas lease to Murphy containing the following provision:
It is hereby specifically agreed and stipulated that in the event a well is completed as a producer of oil and/or gas on land adjacent and contiguous to the leased premises, and within 467 feet of the premises covered by this lease, that Lessee herein is hereby obligated to, within 120 days after the completion date of the well or wells on the adjacent acreage, as follows:
(1) to commence drilling operations on the leased acreage and thereafter continue the drilling of such offf-set well or wells with due diligence3 to a depth adequate to test the same formation from which the well or wells are producing from on the adjacent acreage; or
(2) pay the Lessor royalties as provided for in this lease as if an equivalent amount of production of oil and/or gas were being obtained from the off-set location on these leased premises as that which is being produced from the adjacent well or wells; or
(3) release an amount of acreage sufficient to constitute a spacing unit equivalent in size to the spacing unit that would be allocated under the lease to such well or wells on the adjacent lands, as to the zones or strata producing in such adjacent well.
