The Directional Drilling Survey provides the control of directional drilling of oil wells with calculations and plotting of well planning and survey data in vertical section, plan and x-y-z views, calculations between two survey stations, easy tools to 2D and 3D wells and plot multilateral wells. 

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

Our goal was to create a very low-cost application with the help of experts to share with drilling engineers, technicians, drillers, students and teachers of drilling engineering. 

There is no intention to replace the professional softwares.

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