MG (Computer Modelling Group Ltd.) is a computer software engineering and consulting firm engaged in the development, sale and technology transfer of reservoir simulation software. CMG began as a company known for its expertise in heavy oil, and expanded its expertise into all aspects of reservoir flow modelling. Over the past 32 years, CMG has remained focused on the development and delivery of reservoir simulation technologies that assist oil and gas companies to determine reservoir capacities and maximize potential recovery. To this end, we are continually improving our market-leading line of reservoir simulation technologies to better reflect the changing needs of our users. CMG is a world-class software company traded on the TSX Stock Exchange under the symbol CMG. With over 400 oil and gas companies and consulting firms in more than 50 countries, CMG is one of the largest independent providers of reservoir simulation software in the world. CMOST is the latest product offering in the CMG software suite. It is a state-of-the-art reservoir engineering optimization tool, employing innovative experimental design, sampling and optimization techniques to efficiently determine the reservoir parameters which define the production and ultimate recovery of oil and gas fields. CMG’s Builder creates the base-case reservoir model as the first step in the process. CMOST generates simulation runs automatically from the base model, then submits and analyzes the runs that are created from a range of values for multiple reservoir parameters specified by the engineer. CMOST learns which values produce the best results enabling it to dramatically reduce the number of runs required to find the optimal solution. This is the fastest technique for an accurate history match(es) and reliable production forecasts. CMOST improves the effectiveness of each reservoir engineer by eliminating the tedious labor of individual case generation for hundreds of scenarios. It allows them to focus on the high value effort of interpretation and evaluation of results. CMOST’s power lies in modern experimental design and optimization algorithms which vary multiple parameters simultaneously to find the optimal solution – something a human cannot do. CMOST dispatches to a cluster of computers or a single computer and interprets the results of numerous runs, terminates non-physical solutions and narrows the search space rapidly to reach not just local maximums or minimums, but the ultimate best case. Solutions to reservoir models with trillions of possible combinations and permutations can often be found in fewer than 1000 runs. CMOST helps engineers create more accurate models in dramatically less time and allows asset managers to have a greater degree of confidence in the forecasts, multiplying the team’s effectiveness many fold.
