An application I wrote for Windows (in C#) to provide a quick method to:
- Extrapolate and interpolate depths and dip from directional drilling data, using the minimum curvature method
- Calculate dip between two given data points.
- Perform lag / annular velocity calcuations.
Minimum curvature method detailed here.
It's something I made for my own purposes, and to make something useful while learning some C#, but if you find it useful, feel free to use it, distribute it etc.
Extrapolation Example:
Interpolation Example:
Dip Example:
Tool will also provide a annular velocity / lagtime calculation, as detailed here.
Or, simply: 
, with optional inputs to account for HWDP and
collars.
