IMEX™ is one of the world’s fastest conventional black oil reservoir simulators. IMEX is used to obtain history-matches and forecasts of primary, secondary and enhanced or improved oil recovery processes where changing fl uidcomposition and reservoir temperature are not important factors for accurate modelling of hydrocarbonrecovery processes.

IMEX models production from conventional sandstone and carbonate reservoirs, including the effects of naturalfractures, and is widely used to model primary production of gas and liquids from hydraulically fractured shaleand tight sand reservoirs. IMEX includes features such as local grid refi nement, comprehensive well management,pseudo-miscible option, polymer fl ooding, horizontal wells, dual porosity/permeability, fl exible grids, gas adsorptionand many more. Use IMEX for screening prospects, setting up pilot designs, monitoring and optimizing fi eld opera-tions, and improving production performance.

IMEX models multiple PVT and equilibrium regions as well as multiple rock types and has fl exible relative permeability choices. Regardless of the size or complexity of your reservoir problem, IMEX is an effective tool for a broad range of reservoir management issues.

Finally, IMEX is integrated with CMOST™ to facilitate rapid history matching and optimization of reservoir management workfl ows with uncertainty assessment.

BENEFITS

Achieve simulation results faster than any other conventional black oil simulator

Ability to quickly screen a variety of recovery mechanisms before moving to more complex simulations

Accurate modelling of the matrix-fracture transfer in fractured reservoirs

Use the speed of IMEX to model shale gas adsorption effects

Fast and easy transition to EOR process modelling in GEM™ and STARS™

UNCONVENTIONAL

Gas adsorption is a major issue in unconventional gas recoveryand IMEX can be used to model the adsorption effects in shaleand coal bed methane (CBM) reservoirs. In addition, IMEXincorporates one of the most sophisticated meansof modelling naturally or hydraulically fractured reservoirs.Users can select many different fracture models whichallow for gravity, re-imbibition, and transient effects,providing accurate simulation of fl uid transfer in a naturallyfractured reservoir system. Detailed hydraulic fractureresponse under multi-phase non-Darcy fl ow conditions,and the stimulated areas of tight/shale gas reservoirs,can all easily be analysed.

RESERVOIR FLUID CHARACTERIZATION

IMEX models multiple fl uid systems, including condensates and volatile oils, and allows API tracking for density segregation and mixing effects in the hydrocarbon system. IMEX can model secondary recovery processes such as waterfl ood and gas injection, and some EOR processes such as miscible and pseudo-miscible injection;polymer injection; and WAG processes. IMEX also allows for incompatible water mixing and solidscale formation within the reservoir and well system.

COUPLED SURFACE NETWORK MODELLING

IMEX is used to model coupled subsurface and surface network models of onshore and offshore fi elds, including onshore gas storage fi elds and deepwater offshore oilfi elds in the Gulf of Mexico and the Santos Basin.These programs are coupled at the time-step level,allowing accurate forecasting and scheduling of gas fi elddevelopment. Various types of contract constraintsand controls are available. Multiphase fl ow in boththe gathering system and wellbore is handled, providingthe fl exibility to evaluate gas delivery to various plants, to determine optimal compression, to use differentcompressor specifi cations, to design gas injections, and to optimize fi eld recovery. IMEX seamlessly links to several3rd party surface pipeline network simulators.
