Defining The Lessee’s Covenants to Drill and Develop a Lease
Implied covenants are obligations that are not expressly imposed by a contract, but which courts nevertheless find are binding on one or more parties to the contract. Courts routinely hold that oil and gas lessees are bound by several implied covenants. This paper reviews the various implied covenants that have been recognized as binding oil and gas lessees, and examines the justifications for recognizing those covenants. The paper then discusses various issues that sometimes arise in implied covenants disputes, including the remedies that are available, certain procedural issues, and whether a lessee must continue to perform his implied contractual duties while a lawsuit is pending in which a lessor argues that a lease is invalid or that the lease is no longer in effect. Finally, the paper addresses the application of implied covenants in situations involving new technology and discusses the application of implied covenants in shale plays.

Three years later, the Pennsylvania Supreme Court again stated that a lessee was bound by an implied covenant of reasonable development, and just a few years later, the same court held that lessees are bound by an implied covenant to protect the leased premises against drainage. Ohio soon followed suit in recognizing implied
