Does the term “by the lessee” in an oil and gas lease extend the lease?

32. If the words "by the lessee" are present in an oil and gas lease, it removes all doubt as to who is required to drill to satisfy the drilling requirement and thereby extend the lease. Even without the words, however, the lessee is still likely the party who must complete the drilling. This is so because of the purpose of the oil and gas lease: “Such contracts are almost universally held to be made for the general purpose of developing the premises by the lessee, and the uniform tendency on the part of the courts has been to place such a construction on their terms as will carry out the terms, intent, and purpose of the agreement.” Earp v.
