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).
The newest version of MI-PVT, version 3.0 is now available. The latest version includes:

  • Standard cubic EOS and CPA for associating components (e.g. MeOH, MEG and water)
  • Hydrate calculations with CPA
  • Multiphase PT flash calculations
  • Reservoir fluid characterization
  • Calculation of phase envelopes and saturation points.
  • Simulation of swelling tests.
  • Fast prediction of Minimum Miscibility Pressures (MMP).
  • Indicator for sensitivity to numerical diffusion in finite difference simulations.
  • Minimum Miscibility Enrichment (MME) simulation tool.
  • Dispersion-free 1D simulation by the method of characteristics (MOC).
  • A fast numerical 1D simulator for visualization of drive mechanism in
    miscible/near-miscible displacements.
  • PVT experiments (CME, DDE, CVD and sequential separator test).
  • Viscosity calculations (F-theory and LBC).
  • Flexible input of experimental data.
  • Regression of experimental data including MMP data.

A fluid database is now included for educational and training purposes, containing 13 reservoir fluids with related PVT experiments. The database includes upwards 5000 experimental data points.
