Files listed in the table below are for the Alaska OCS Region only. Well Information includes information on borehole activities such as drilling activity, counts on the number of boreholes completed, and number of shut-in's. Additional information includes the lease number, well name, spud date, the well class, surface area/block number, and statistics on well status summary. Additional files are available on well completions and well tests.

• All surveys are referenced to grid north (with the exception of Northstar in true north) in the native map projection of the block containing the surface location of the survey. For some old surveys the north reference was not marked and was assumed by BOEM to be grid north.
• In an effort to improve the quality of our downloadable data, we are now exporting bottom hole locations as calculated from the directional survey associated with the well.
• The AK coordinate values were derived using the North American Datum (NAD) 1983.
• BSEE transitioned to a PPDM data model for directional survey storage and management on July 25-26, 2020, and the Directional Survey (Azimuth) file LAST_UPDATE column was refreshed to reflect this change. Calculated values are derived by minimum curvature method and differences in data over previous versions of the Directional Survey (Azimuth) file may be observed.
