IMEX - Three-Phase, Black-Oil Reservoir Simulator

IMEX, one of the world's fastest conventional black oil reservoir simulators is used to obtain history matches and forecasts of primary, secondary, and enhanced or improved oil recovery processes. In addition, IMEX models complex, heterogeneous, faulted oil and gas reservoirs, using millions of grid blocks, to achieve the most reliable predictions and forecasts. Use IMEX for screening prospects, setting up pilot designs, monitoring and optimizing field operations, and improving production performance.

With IMEX, you will:

  • Achieve simulation results faster than with any other black-oil simulator
  • Quickly screen a variety of recovery mechanisms before moving to more complex simulations
  • Accurately model the matrix-fracture transfer in naturally and/or hydraulically fractured reservoirs
  • Use the speed of IMEX to model shale gas adsorption effects
  • Easily transition to EOR process modelling in GEM and STARS
  • Seamlessly interface with CMOST to facilitate rapid history matching and optimization of reservoir management workflows


Regardless of the size or the complexity of your reservoir problem, IMEX is an effective tool for a broad range of reservoir management issues.
