IMEX - Three-Phase, Black-Oil Reservoir Simulator
IMEX, the world's fastest black oil reservoir simulator, is used to model primary and secondary oil recovery processes in conventional and unconventional reservoirs. Use IMEX for screening prospects, setting up pilot designs, monitoring and optimizing field operations, and improving production performance. Regardless of the size or the complexity of the reservoir, IMEX is an effective tool for a broad range of reservoir modelling and management issues.
With IMEX, you will:
- Quickly screen a variety of recovery mechanisms before moving to more complex simulations
- Model complex hydraulic fracture networks, and all associated effects, to accurately history match field results
- Accurately model the matrix-fracture transfer in fractured reservoirs
- Complete fast and easy transition to EOR process modelling in GEM and STARS
- Seamlessly integrate with CMOST for rapid history matching and optimization of reservoir management workflows
- Model different types of reservoir fluids (under-saturated & saturated oils, volatile oils, gas condensates, dry & wet gas reservoir fluid systems)
- Select from multiple gridding options (Cartesian, radial, orthogonal and fully non-orthogonal corner point grids)
- Dual continuum options for modelling naturally fractured reservoirs and gravity segregation processes
- Seamlessly integrate with CMOST to facilitate rapid history matching and optimization of reservoir management workflows
- Model longitudinal or transverse bi-wing hydraulic fractures and complex hydraulic fractures networks through SRV
- Import third-party hydraulic fracture simulation data for better propped fracture characterization
- Utlize various correlations to capture the effect of non-Darcy flow
- Achieve reliable gas-in-place and reserves estimates by modelling adsorbed gas contribution to production in shale and CBM reservoirs
- Optimize well and fracture spacing to increase production, NPV and EUR with CMOST
- Predict and compare reservoir performance by applying secondary recovery techniques (water injection, polymer injection, pseudo-miscible injection, in continuous and WAG)
- Model adsorption, polymer degredation, shear thinning and non-linear viscosity mixing
- Inject chase gas that has different properties than the solution gas component
- Couple to third-party surface network simulators to model more complex (e.g. looped) surface networks
- Create explicitly-coupled subsurface and surface network models, including onshore gas storage fields and deep water offshore oil and gas fields
- Coupled modelling allows engineers to trouble-shoot bottlenecks in the entire reservoir and surface network system
- Decrease project turn-around time
- Run more simulation jobs simultaneously and get results faster than before
- Additional parallelization increases speed-up when jobs are submitted on a higher number of cores
- Reduce capital expenditures with efficient use of current IT computer hardware
- Quickly load results of large models with the new standardized and compressed SR3 files to maximize productivity
iSegWell, an intelligent segmented wells module in IMEX, accurately and realistically models the flow and pressure change throughout wellbore branches, tubing strings and equipment.
- Wellbore modelling for gravity and frictional pressure losses (horizontal & multi-lateral wells, downhole equipment, tubing)
- Define and use non-standard flow control devices (FCDs) to optimize injection and production strategy
