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 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 coordinate values were derived using the North American Datum (NAD) 1927.
