MI-PVT 3.0:
including capillary pressure in VLE calculations

Miscible injection processes require a thorough understanding of the phase behavior of the fluids involved, i.e. the reservoir fluid and the injection fluid and how these fluids mix during flow through a porous media. MI-PVT is a PVT simulation tool based on state-of-the-art theory and algorithms making it possible to predict the relevant phase behavior of the fluids in a gas injection process.

Capillary pressure can now be included in phase envelope calcuations as well as in PT-flash calculations and simulation of PVT experiments.
A demo version of MI-PVT 3.0 with all available features and a built-in fluid database is available. Please contact us at info(at) to obtain the demo version (download).
