WellSim — Nodal Analysis
A petroleum-engineering simulator for modelling oil, water, and gas well performance, reserves, forecasts, and artificial lift.
Field notes
The application organizes engineering work into linked modules rather than presenting a single calculator. Production rows can be pasted from the clipboard or imported as CSV, while reserve estimation combines production history, static pressure surveys, and material-balance methods. Its ESP section includes separate matching paths for stages, pump wear, and separator efficiency, and the forecast module offers both THP-coupled nodal calculations and a fixed minimum flowing-pressure option.
