Petroleum Field Calculator app for iPhone and iPad

For use by professionals, students, and safety personnel in the upstream oil and gas industry. A simple and easy way to perform calculations of many common formulas used in oilfield operations such as drilling and well control. Calculations can be easily switched between imperial and metric (SI) units. Conversion factors for automatically converting units are also included. Great for situations when you don’t have access to formulas or desktop software. Also great for use in remote areas in the oilfield where there might not be internet access since the app has a self contained searchable list of many calculations.
