Well Drilling Free is an Android app developed by Julio Cesar Duran Chavez. It falls under the Lifestyle category and offers a realistic drilling simulation experience with actual calculations.

The app provides users with the ability to simulate well drilling operations and perform various calculations related to drilling. Users can calculate the volume directly, circulation time, and pump strokes. They can also determine the hydrostatic pressure and depths MD and TVD. Additionally, the app allows users to run casing, perform casing cementation, and design the well geometry for each perforated section. Users can also select the appropriate tools such as DPs, DCs, and CSG, as well as adjust the angle of deviation.

Well Drilling Free offers a comprehensive set of features for those interested in drilling simulations. With its realistic calculations and intuitive interface, it provides a valuable tool for professionals in the drilling industry or anyone interested in learning more about the drilling process.
