• 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 the bureau 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.
