Directional Survey To Log Curves

This transformation generates new curves relative to MD based on directional survey data.  Petra generates an X and Y curve automatically.  This log transformation is available on the Advanced Transforms tool.

X-Offset Log Curve – This option sets the name of the X Offset Curve.  By convention, offsets to the north are positive and offsets to the south are negative.  By default, Petra will name this curve “XOFFSET”; to change the filename enter a new name or select a different curve from the dropdown box.  There is no option to turn off this curve.

Y-Offset Log Curve - This option sets the name of the X Offset Curve.  By convention, offsets to the east are positive and offsets to the west are negative.  By default, Petra will name this curve “YOFFSET”; to change the filename enter a new name or select a different curve from the dropdown box.  There is no option to turn off this curve.

TVD Curve – This option creates a True Vertical Depth (TVD) curve relative to MD.  By default, Petra will name this curve “TVD”; to change the filename enter a new name or select a different curve from the dropdown box.  The option box to the left toggles this curve’s creation on and off.

MD Curve - This option creates a Measured Depth (MD) curve relative to MD.  By default, Petra will name this curve “MD”; to change the filename enter a new name or select a different curve from the dropdown box.  The option box to the left toggles this curve’s creation on and off.

DIP Curve - This option creates a wellbore dip/inclination curve relative to MD.  By default, Petra will name this curve “DIP”; to change the filename enter a new name or select a different curve from the dropdown box.  The option box to the left toggles this curve’s creation on and off.

AZM Curve - This option creates a wellbore azimuth curve relative to MD.  By default, Petra will name this curve “DEVI”; to change the filename enter a new name or select a different curve from the dropdown box.  The option box to the left toggles this curve’s creation on and off.
