A Log is a measured value at select intervals along a well. The Log is imported into a WellData module to create values down a well. A Log can use discrete values along the well trace or interval values with From Depth and To Depth.

 

A Log can use location information in any of these forms:

  1. Pre-computed X, Y, and Z measurements. Z is the "down-the-hole" depth value, usually recorded as elevations.
  2. Azimuth, dip, and measured depth. The X, Y, Z position is calculated automatically from this information.
  3. Directional survey information (Azimuth, Dip, and measured depth). The X, Y, Z position "down-the-hole" is computed on the Well Path tab of the WellData module in the Property Manager.
