The Department of the Interior is required (43 U.S. Code § 1865) to “…conduct a continuing investigation to determine an estimate of the total discovered crude oil and natural gas reserves by fields (including proved and indicated reserves)…of the Outer Continental Shelf.” In order to meet this requirement, BOEM develops independent estimates of economically recoverable amounts of oil and gas contained within discovered fields by conducting field reserve studies. The reserve estimates are revised periodically to reflect new information obtained from exploration, development, and production activities.
