The U.S. Dept. of the Interior Minerals Management Service has revised the standards for reporting gas production volumes from leases on federal and Indian properties. The agency has changed the standard pressure base from 15.025 psia to 14.73 psia for reporting gas production volumes and Btu heating values in the Gulf of Mexico while keeping the standard temperature base of 60o F the same. This reporting standard applies to production on federal leases, on- and offshore, beginning with the sales/production month of September 1998.
