Oil and Gas and Sulphur Operations on the Outer Continental Shelf-Suspension of Operations for Exploration Under Salt Sheets

MMS is modifying regulations that govern suspensions of operations for oil and gas leases on the Outer Continental Shelf (OCS). The amendment covers instances where oil and gas lessees begin timely interpretation of geophysical data early in the lease term, but the analysis proves inconclusive because of problems caused by the existence of salt sheets underlying the seabed and overlying possible hydrocarbon deposits. In such cases, the rule allows lessees to apply for a suspension of operations to complete the necessary geophysical interpretation before drilling a well. To qualify for a suspension of operations, the lessee must show it has made and will continue to make substantial efforts and financial commitment to process and reprocess its geophysical data.
