"PE Essentials" is a software tool that is currently under development for use by Reservoir Engineers and Production Engineers. PE Essentials is targeted towards tools for both unconventional wells/reservoirs as well as conventional wells/reservoirs.
I have completed a suite of tools called Petroleum Engineering Essentials (PE Essentials). The tools include: PVT/Rel Perm Generator, EOS Simulator, Basic reservoir Simulator, Monte Carlo Volumetrics, Unconventional Well Forecast/Simulator, Hydraulic Fracture Design, Stream Tube Waterflood Simulator, Monte Carlo Decline Curve Forecast, Decline Curve Analysis, Scoping Economics, THP-BHP Conversion for Oil and Gas Well, EOR Screening Tool and Miscible/Immiscible CO2/WAG Waterflood Simulator, Multi-Tank Material Balance, Quick Log Analysis. The tool is free to anyone who wants to try it out (download it from my website at www.eastexpetroleum.com/?page=PE_Essentials). There is also an example report presenting use of some of the modules on the website.
The 2017 version (updated January 17) of PE Essentials is 64bit and includes the following modules:
The modules continue to be checked for bugs and updated as required. Check back often for version updates and as always, all feedback is welcomed.
