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 and plan views to help technicians, drillers, toolpushers and engineers of petroleum industry.

NOTE: This app is compatible with iOS 6. For iOS 7 or greater we recommend the new app "Directional Drilling" designed for both iPhone and iPad and with more features. Please, check our portfolio on the App Store.

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

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

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