Computer Modelling Group Ltd., a computer software technology company, develops and licenses reservoir simulation software in Canada and internationally. The company offers CMOST-AI, an intelligent optimization and analysis tool that offers solution for reservoir by combining statistical analysis, machine learning, and non-biased data interpretation; IMEX, a black oil simulator that is used to model primary and secondary oil recovery processes in conventional and unconventional oil and gas reservoirs; GEM, an equation-of-state reservoir simulator for compositional, chemical, and unconventional reservoir modelling; STARS, a thermal and processes reservoir simulator for the modelling of steam, solvents, air, and chemical recovery processes; and CoFlow, a reservoir and production system modelling software that allows reservoir and production engineers to make informed decisions on large integrated oil and gas projects in Canada. It also provides Builder, a pre-processor that simplifies the creation of simulation models by providing a framework for data integration and workflow management between various data sources; Results, a post-processor that helps in enhancing understanding and insight into recovery processes and reservoir performance; WinProp, a fluid property characterization tool; and Autotune artificial intelligence solutions that tune the model for optimal run time. In addition, it offers professional services comprising specialized support, consulting, training, and contract research services. The company was founded in 1978 and is headquartered in Calgary, Canada.
