## Description

This is an important tool for Oil and Gas. By using it and sharing your experience with your friends you are contributing to the viability of this project. thanks

This application uses the formulas to calculate the survey parameters (diff of TVD, N/S, E/W, DLS) between two stations of the methods:

1. Tangential
2. Balanced Tangential
3. Minimum Curvature
4. Radius of Curvature
5. Angle Averaging

Also available the formulas of the methods.

This app was developed based in existing spreadsheets. There is no comparison with any other software.

You can contribute with suggestions for improvements, reporting bugs and spreading it to your friends.

Our portfolio for Directional Drilling available on the App Store:
