Notice to Lessees (NTLs)

Notices to Lessees and Operators (NTLs) are formal documents that provide clarification, description, or interpretation of a regulation or OCS standard; provide guidelines on the implementation of a special lease stipulation or regional requirement; provide a better understanding of the scope and meaning of a regulation by explaining BSEE interpretation of a requirement; or transmit administrative information such as current telephone listings and a change in BSEE personnel or office address. Letters to Lessees and Operators (LTLs) and Information to Lessees and Operators (ITLs) are also formal documents that provide additional information and clarification, or interpretation of a regulation, OCS standard, or regional requirement, or provide a better understanding of the scope and meaning of a regulation by explaining BSEE interpretation of a requirement.

For shallow-water leases issued from 2001 through 2003, the royalty suspension provisions in the lease instrument define deep gas as any gas production from a completion in a new gas reservoir (one not previously produced on any current lease) with the top of the perforated interval 15,000 feet or greater subsea. The reference to “completion” in this definition includes completions in both new and sidetrack wells. Accordingly, the lease instrument grants a 20 BCF royalty suspension volume (RSV) not only to new wells, but also to sidetrack wells.
