Hold Section

This tool is useful for defining planned kick off points, or extending the trajectory beyond a target.You can add straight-line projection to either a MD, TVD or to a VSEC.

Varying Curvature Scan

Varying Curvature is a survey calculation method which as a by product produces a value called Inconsistency.

MD Interval

The Inconsistency can be considered to be the effect on the bottom hole location of each individual survey station.

If the survey station is missing ...

Shift to bottom hole location

MD Interval ... the Inconsistency is the amount by which the bottom hole location would move in space.
