Oilfield Assistant - Formulas

Oilfield Assistant gathers over 100 calculations/equations from the Oil and Gas world. It also includes Casing/Drill Pipe/HW/DC/Tubing Specifications and a convenient Oilfield Units Converter!

To make it super easy for you to access all the formulas and calculations you need, we've divided them in the following categories:

- Basic Drilling Formulas

- Applied Drilling Formulas

- Directional Drilling formulas

- Fluid related formulas

- Hydraulic formulas

- Well Control formulas

*units are 100% customizable from the setting's option.

You will also find the API data for tubulars (Casing, Drillpipe, Heavy Weight Drillpipe & Tubing) and other useful references under:

- tables & References

Finally, our Unit Converter, a straight and simple interface to convert between the units that our relevant in the Oil & Gas Industry like: Area, Diffusivity, Density - Mud Weight, Energy, Flow Rate, Flow (Pump Output), Force, Length, Mass, Pressure, Power, Temperature, Time, Velocity, Viscosity, Volume & Yield Strength

A MUST for oilfield workers! It doesn't matter if you are a company man, driller, mud engineer, field engineer, rig hand, cementer, logger, etc... there's something here for you!

The app uses formulas from Drilling Data Handbook (IFP Publications).
