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