Computer Modelling Group Ltd., a computer software technology company, engages in the development and licensing of reservoir simulation software and related services in Canada and internationally. The company offers CMOST-AI, an intelligent optimization and analysis tool that offers solution for reservoir by combining advanced 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 reservoirs; and GEM, an equation-of-state reservoir simulator for compositional, chemical, and unconventional reservoir modelling. It also provides STARS, a thermal and processes reservoir simulator for the modelling of steam, solvents, air, and chemical recovery processes; 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; and 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. 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. Further, it provides professional services comprising specialized support, consulting, training, and contract research services. The company was founded in 1978 and is headquartered in Calgary, Canada.
