Well Offsets Tool

This tool computes the offset of a point on the NAD83 datum with respect to the unit boundaries in which it is located. The tool also computes the corner coordinates and boundary azimuths for the corresponding Grid Area, Section and Unit.

Input: The NAD27 or NAD83 coordinates of a well or any point.


  • The NAD83 latitude and longitude of every corner of a Grid Area, section and unit in which the point is located;
  • The forward and back azimuths of every boundary for each Grid area, section and unit;
  • The North, South, East and West point offset with respect to the unit boundaries.

Note: If you need to convert between UTM and Geographic coordinates, please use the Canadian Geodetic Survey Division On-Line tool called TRX (opens in new window)
