As Principal Reservoir Engineer in PETRONAS, I’m pleased to share our experience working with CMG’s simulation software and technical support during the Megah subsurface evaluation and development studies. The support from CMG team was exceptional, especially Nader Ghadami. The Megah project involved a technically challenging carbonate reservoir system, requiring close integration of well test interpretation, pressure transient analysis, and dynamic single well modelling to understand reservoir connectivity, tested volume distribution, and production sustainability. CMG’s simulation tools played a key role in supporting these evaluations by enabling robust numerical modelling and sensitivity analysis aligned with the geological and pressure data available from the well. That enabled our team to successfully upgrade the single well model to full field. Throughout the study, CMG provided reliable technical support and responsive engagement, supporting the modelling workflow from early concept screening through to structured technical reviews and internal decision forums. Their team demonstrated a strong understanding of carbonate reservoir behaviour, well test dynamics, and model based uncertainty evaluation, while maintaining a collaborative and professional working relationship with our subsurface team. The use of CMG’s tools and technical input contributed meaningfully to our ability to interpret Megah test results, assess reservoir connectivity, and evaluate development relevant scenarios in a technically consistent and auditable manner. Based on our experience, we are pleased to recommend CMG to teams undertaking complex subsurface and dynamic modelling studies, and we look forward to continued collaboration as our projects progress.

CMG solutions and technical support have greatly enhanced our teaching by providing students with hands-on experience using industry-standard reservoir simulation tools. The recent Thermal EOR workshop delivered by Eng. Kavish Grover was highly engaging and technically valuable, effectively linking theory with real-field applications. The best thing about CMG is its strong commitment to education, excellent technical support, and robust simulation software that prepares students for professional practice.

CoFlow™ and IMEX™ are a power duo for solving flow assurance and maximizing production.

At Zama, our field poses significant challenges that demand highly accurate, high-resolution simulation. With CMG’s CoFlow and IMEX, we seamlessly model flow, pressure, and temperature across the reservoir and production system.

This powerful combination helps us tackle flow assurance issues while keeping production optimized.

Accurate results. Scalable models. Exceptional support. That’s why we trust CMG’s GEM™.

GEM has consistently delivered accurate, stable, and efficient results that have enabled us to design, optimize, and de-risk our CCS project. It is indispensable in understanding CO₂ plume behavior, trapping mechanisms, and reservoir integrity over the project lifecycle.

GEM’s scalability for large, complex 3D models has allowed our team to simulate both short-term injection performance and long-term storage security with confidence. In addition to the tool itself, another strength of CMG is its support team, which have been instrumental in our success.

CMG STARS gives us the platform to model complex thermal and chemically reactive systems with dynamic flows. We’ve used CMOST as a tool to quantify the potential production ranges spanning a set of interacting uncertainties for the reservoir conditions and ranges in the reactivity for the designed chemical reactions. It is highly impossible to find another platform that does this.

I am the chairman of IATMI Komda Bandung and I am an associate professor at Petroleum Engineering Department ITB. CMG is very helpful for my students to study the reservoir modeling. CMG has a great feature for optimization.

First of all, we want to express on behalf of the academic community of the Universidad Surcolombiana our thanks to the Computer Modelling Group Ltd. Company for the training received during June 03 & 04, 2025 at the facilities of our university, Sala CPIP-USCO. Secondly, we are very grateful for his valuable collaboration and for the excellent work done by Mr. José Santos during the training course on the use of the STARS™ Module of the CMG platform; we especially want to highlight the great pedagogical and technical skills and the interest of Mr. José Santos. It was an excellent presentation that will undoubtedly result in the academic quality of our graduates and will be an important pillar for our research projects. Thanks again, to you, to Eng. Argenis Álvarez R. and Eng. José Santos for the time provided and the collaboration provided.

IMEX™ delivers reliable, precise simulation – backed by CMG’s exceptional support

CMG’s Academic License makes learning and research seamless and intuitive. One of the biggest challenges for students in reservoir simulation is managing complex input files. CMG’s Builder solves this with an intuitive GUI that lets users focus on analysis instead of setup. The Academic License provides full access to CMG’s suite — Builder™, Results™, IMEX™, GEM™, STARS™, and CMOST™ — supporting a wide range of research, from CCS and EOR to model validation and machine learning datasets. Its ease of use and comprehensive capability make CMG’s Academic License one of the best choices for students and researchers in reservoir simulation.

CMG’s GEM™ has been instrumental in evaluating subsurface risks and asset value in our natural gas dissolved-in-water fields. Its ability to model complex geomechanical behavior, combined with CMG’s excellent technical support, has made it a trusted tool in our operations.

Using CMG’s GEM™, we optimized CO₂ injection while accurately modeling structural and solubility trapping. GEM’s strong THMC capabilities made our research both efficient and impactful.

CMG’s GEM™ is central to our CO₂ storage modeling in the Lusitanian Basin under the EU-funded PilotSTRATEGY project. Its ability to simulate long-term plume behavior, trapping mechanisms, and geomechanical effects helps us evaluate storage integrity with confidence.

GEM™ is the best simulator for CCS, accurately modeling physics, geomechanics, and CO₂ behavior

RESULTS™ has been our trusted Simulation companion for over 30 years

CMOST™ changed the game by helping us understand uncertainty, accelerate history matching, and deliver more robust results.
