  • 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 ...

  • Inconsistency of a single observation

    X 100

    Shift to bottom hole location

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