Computer Modelling Group Ltd., a software and consulting technology company, engages in the development and licensing of reservoir simulation and seismic interpretation software and related services. The company offers CMOST-AI, an optimization and analysis tool that offers solution for reservoir by combining advanced statistical analysis, machine learning, and impartial data interpretation; IMEX, a black oil simulator that is used to model primary, secondary, and tertiary oil recovery processes in conventional and unconventional reservoirs; and GEM, an equation-of-state reservoir simulator for compositional, chemical, and unconventional reservoir modelling. It also provides STARS, a multi-phase, 3D reservoir simulator capable for modelling of thermal and chemical processes; CoFlow, a reservoir and production system modelling software that allows reservoir and production engineers to make informed decisions on integrated oil and gas projects; and Builder, a pre-processor for simulation model building. In addition, the company offers Results, a post-processor that helps in enhancing understanding and insight into recovery processes and reservoir performance with state-of-the-art visualization and analysis; and WinProp, a fluid property characterization tool, as well as ShaleIQ, a physics-driven advanced forecasting solution for unconventional reservoirs. Further, it provides professional services comprising specialized support, consulting, training, and contract research services. The company operates in Canada, the United States, South America, Europe, Africa, Asia, and Australia. The company was founded in 1978 and is headquartered in Calgary, Canada.
