Gravity Toolface
- Gravity toolface is the angular distance the bent sub scribe line is turned, about the tool axis, relative to the high side of the hole
- Gravity toolface = Dir Probe Gravity Toolface + Toolface Offset
- If the inclination of the wellbore is above 5° to 8°, then gravity toolface can be used
- The toolface will be referenced to the highside of the survey instrument, no matter what the hole direction of the survey instrument is at the time
- The toolface will be presented in a number of degrees either right or left of the highside
