This is an important tool for well design and drilling engineering schools at Oil & Gas. By buying this app you are contributing to the viability of this project. Thanks

This app provides the casing shoe depths calculations based on formation pore pressure gradient and fracture pressure gradient using both concepts "bottom-up" and "top-down" and also analysis of the kick effects on the casing setting.

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

Our goal was to create an 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.
