It was not estimated by MMS. 5 Included with Lower 48 States; MMS did not generate separate Lower 48 and Alaska estimates (year end 1986). 6 Includes Alaska. NA=Not available. NE= Not estimated. Notes: Ö See Note 1 at end of section. Ö Onshore indicates estimates for all Onshore plus State Offshore waters (near-shore, shallow-water areas under State jurisdiction). Ö Federal Offshore denotes MMS estimates for Federal Offshore jurisdictions (the Outer Continental Shelf and deeper water areas seaward of the State Offshore jurisdictional boundary). Ö The USGS mean estimates are as of year-end 1993 (onshore and State offshore). The MMS mean estimates are as of year-end 1994. Probable and possible reserves are considered by the USGS to be part of reserve growth but are separately estimated by MMS as unproved reserves. USGS did not set a time limit for the duration of reserves growth; MMS set the year 2020 as the time limit in its estimates of reserve growth in existing fields in the Gulf of Mexico. Excluded from these resource estimates are undiscovered oil resources in tar deposits and oil shales, and undiscovered gas resources in geopressured brines and gas hydrates. Ö Data may not sum to totals due to independent rounding. Source: Federal Offshore: U.S. Department of the Interior, Minerals Management Service.
