Open reservoir engineering is even more awesome, so we made a list. This list is curated from repositories that make our lives as reservoir engineers, hackers and data wranglers easier or just more awesome. In accordance with the awesome manifesto, we add awesome repositories. We are open to contributions of course, this is a community effort after all.
neqsim - Estimation of phase behaviour and properties for oil and gas fluids
PREOS - Computes the fugacity coefficient, compressibility, and density of a gas at a particular temperature and pressure using the Peng-Robinson EoS
zFactor - Calculates the error measures or deviation between different correlations for gas compressibility compared to the original Standing-Katz chart
Rock-Fluid Interaction
arxim - Calculations of multiphase (fluid, mineral, gas) interactions
PhreeQC - Reactions in water and between water and rocks and sediments (speciation, batch-reaction, one-dimensional transport, and inverse geochemical calculations)
Reaktoro - Unified framework for modelling chemically reactive systems
GeoPyTool - Application with geochemical plotting capabilities
pyrolite - Geochemical transformation and visualisation
Geology and Geophysics
GemPy - 3-D structural geological modelling software with implicit modelling and support for stochastic modelling
