CMG (IMEX & STARS)

CMG (Computer Modelling Group) is a fiercely powerful, mathematically brilliant, and deeply respected enterprise software titan based in Canada. It operates as the absolute, heavy-weight direct rival to Schlumberger in the simulation space. CMG built a massive global empire by explicitly dominating "Heavy Oil, Thermal, and EOR (Enhanced Oil Recovery) Simulation." If you are injecting steam, chemicals, or fire into the ground, you use CMG. The absolute core superpower of CMG is its 'STARS' thermal simulator. While standard simulators handle basic oil, STARS is mathematically engineered to simulate the injection of 500-degree steam into dense, tar-like bitumen in the Canadian oil sands. It mathematically calculates the exact phase changes, chemical reactions, and heat transfer occurring miles underground. Because it completely dominates the most highly complex, chemically chaotic Enhanced Oil Recovery projects on earth, offering unparalleled thermal mathematics and massive global trust, it is the inescapable standard for heavy oil extraction, chemical flooding, and modern Carbon Capture (CCUS).
