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.SHOW ALL CONTENT | HIDE ALL INFORMATION
IMEX incorporates one of the most sophisticated means of modelling naturally or hydraulically fractured reservoirs to accurately and efficiently capture transient flow behavior leading to better production forecasts.
- Explicit modelling of hydraulically fractured wells with non-Darcy Flow, and pressure and time-dependent compaction
- Accurate representation of deviated well trajectories and horizontal wells
- Model simple adsorption effects in shale and CBM reservoirs
- Microseismic data import for better hydraulic fracture characterization
- Optimize well and fracture spacing to increase production, NPV and EUR with CMOST
IMEX produces the fastest conventional reservoir simulation results in comparison to other blackoil simulation software. IMEX models complex, heterogeneous, faulted oil and gas reservoirs, using millions of grid blocks to achieve the most reliable predictions and forecasts.
- Full-featured, three-phase, four-component black oil simulator
- Multiple gridding options (Cartesian, radial, orthogonal and fully non-orthogonal corner point grids)
- Dual continuum options for modelling naturally fractured reservoirs
- Streamlines output for enhanced visualization of flow direction and magnitude
Use IMEX to propose new drilling locations and predict recovery for waterflooding in complex and heterogeneous reservoirs. Predict and compare reservoir performance by applying other secondary recovery techniques such as the injection of polymer, immiscible and pseudo-miscible gas, WAG, and solvents
- Predict performance of other tertiary recovery techniques (polymer injection, miscible and pseudo-miscible injection, WAG)
- Relative permeability with hysteresis, end-point scaling
- Capillary pressure with hysteresis
IMEX models multiple-fluid systems, including condensates and volatile oils, and allows API tracking for density segregation and mixing effects in the hydrocarbon system.
- Three-phase and up to four-component fluid models
- Two-phase and up to three-component models
- Control of rate of dissolution of gas in oil phase or vaporization of oil into gas phase
IMEX can be used in conjunction with third-party surface facilities software to create fully-coupled subsurface and surface network models, including onshore gas storage fields and deepwater offshore oilfields.Coupling surface network modelling with reservoir simulation allows for troubleshooting bottlenecks and total system optimization from reservoir to point of delivery.
- Seamless integration with third-party surface network modelling software
- Use of hydraulics tables for modelling branched surface networks
- Predict full field performance
- Ability to model single or multiple reservoirs
- Multi-phase flow in both the gathering system and the wellbore
- Simultaneously optimize the reservoir and surface systems using CMOST
iSegWell is an advanced analytical wellbore modelling tool in IMEX that models complex flow regimes and pressure change throughout wellbore branches, tubing and equipment. This powerful combination enables the design of complex multi-phase flow in heterogeneous reservoirs. iSegWell includes:
- Wellbore and tubing string pressure-drop methods
- Tubing string opening, ending and perforation pressure-drop methods
- Tubing string equipment pressure-drop methods
- Wellbore branch packers to block fluid flow to produce segregated pressure regions
- Tubing string gas lift

This course introduces the latest features of pre- and post-processing technologies used with CMG simulators. These include Builder, which provides data preparation for black oil (IMEX), compositional (GEM) and advanced thermal/chemical process (STARS) simulators. Note: This course was formerly known as 'Introduction to IMEX, Builder & Results'.
This course introduces the method of creating PVT data for miscible floods for both IMEX and GEM. Participants will learn how to create a 1D model to simulate core studies using GEM and history match core flood lab data.
