INPEX Corporation Oil, Gas and Chemicals 3364 $2.3B Japan Computer Modeling Group CMG GEM Reservoir Simulation 2013 n/a In 2013, INPEX Corporation implemented CMG GEM for Reservoir Simulation. The deployment reflects a multi-year engagement between INPEX and Computer Modeling Group, with CMG GEM serving as the primary reservoir simulator for full physics compositional and CO2 storage modelling supporting subsurface decision-making across Japan and related regional projects. The implementation leverages CMG GEM capabilities for compositional simulation, CO2 storage and CCS modelling, and multiphase flow analysis to evaluate injectivity and storage performance. CMG GEM is used to run scenario-driven reservoir simulations that inform injection strategy and storage forecasting, integrating domain workflows for subsurface characterization and injection planning. Operationally the CMG GEM implementation is scoped to INPEX subsurface and reservoir engineering activities in Japan and adjacent regional projects, and it is positioned to support carbon capture and storage programs. Governance is reflected in a sustained vendor relationship with CMG and the embedding of CMG GEM outputs into subsurface decision workflows, and CMG public materials reference INPEX's use of CMG GEM to validate CCS and compositional simulation practice.
Oil And Natural Gas Corporation India Oil, Gas and Chemicals 24378 $74.5B India Computer Modeling Group CMG GEM Reservoir Simulation 1992 n/a In 1992, Oil And Natural Gas Corporation India implemented CMG GEM in the Reservoir Simulation category. CMG customer testimonials report ONGC has used CMG reservoir simulation software for reservoir modelling, history matching and EOR studies on Indian assets, establishing a long running relationship between ONGC and CMG products. The implementation centered on compositional reservoir simulation capabilities provided by CMG GEM, supporting compositional and EOR workflows such as compositional flow modelling, phase behavior resolution, iterative history matching and scenario-based EOR process simulation. CMG GEM was used to build and calibrate reservoir models, execute compositional runs and run sensitivity analyses consistent with Reservoir Simulation practices. Operational coverage targeted ONGC reservoir engineering and EOR teams working on Indian asset portfolios, with CMG GEM integrated into reservoir modelling and recovery planning workflows. Governance emphasized model calibration and iterative history matching as part of standard reservoir engineering procedures, aligning simulation outputs to field data for recovery planning and EOR decision support. The work reflects ONGCs long-term compositional and EOR modelling needs, and CMG GEM usage is indicated as supporting compositional/EOR workflows to improve recovery planning in India according to the source testimonial.
Petrobras Oil, Gas and Chemicals 41778 $16.7B Brazil Computer Modeling Group CMG GEM Reservoir Simulation 2016 n/a In 2016, Petrobras integrated CMG GEM into its reservoir simulation pipeline. CMG GEM was deployed as a core compositional simulator within the Reservoir Simulation environment to support pre-salt field studies in Brazil, providing compositional PVT and multi-component flow modelling for subsurface planning. The implementation combined CMG GEM with other CMG simulators including IMEX, establishing a mixed-simulator workflow for black-oil and compositional scenarios. Petrobras collaborated with Computer Modeling Group on CoFlow-related development and solver-acceleration work to enhance compositional solver performance and numerical stability. The deployment emphasized HPC optimisation in Brazil, embedding solver-acceleration techniques into batch and parallel run workflows to enable large-scale compositional studies. Operational coverage focused on reservoir engineering and subsurface modelling teams performing field development planning and storage analyses. Governance centered on an integrated simulation pipeline and joint vendor collaboration for solver tuning and performance engineering, with rollouts targeted to pre-salt campaigns. The program improved simulation runtimes and enabled extensive compositional studies used for field development and storage analyses.
