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, an optimization and analysis tool that offers solution for reservoir by combining statistical analysis, machine learning, and impartial data interpretation; IMEX, a black oil reservoir 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 software for compositional, chemical, and unconventional reservoir modelling. It also provides CoFlow, a integrated production system modelling software that allows reservoir and production engineers; STARS, a thermal and advanced processes simulator in thermal, chemical enhanced oil recovery, and other advanced processes; and Builder, a pre-processor for simulation model building. In addition, the company offers Results, a post-processor, which delivers visualization and analysis capabilities to provide insight into reservoir characteristics, recovery processes, and reservoir performance; Focus CCS, a validate asset viability in minutes; WinProp, a fluid property characterization tool, and CO2LINK, a dynamic link between CCS simulator and the Transient wellbore simulator for the modelling of complex CO2 phase transition systems; as well as ShaleSim, a platform that provides fracture-to-production optimization. Further, it provides professional services, comprising specialized support, consulting, training, and contract research services. It operates Canada, the United States, South America, the Eastern Hemisphere, Europe, Australia, and Asia. Computer Modelling Group Ltd. was founded in 1978 and is headquartered in Calgary, Canada.
