- = No Data Reported;  -- = Not Applicable;  NA = Not Available;  W = Withheld to avoid disclosure of individual company data.
Notes: W -- Individual state volumes are withheld to avoid disclosure of operator-level reserves data, due to statistical precision requirements, or due to other data quality reasons. The individual state volumes are included in the U.S. Total volume. The volumes in the table above are crude oil ONLY (aka Black Oil), excluding lease condensate. The production estimates in this table are based on data reported on Form EIA-23L, "Annual Survey of Domestic Oil and Gas Reserves." They may differ from the official Energy Information Administration production data for crude oil contained in the "Petroleum Supply Annual."  See Definitions, Sources, and Notes link above for more information on this table.
