How CMG and NVIDIA Are Rewriting Reservoir Modeling

A new CMG and NVIDIA partnership sharply cuts simulation time for carbon capture, geothermal, and oilfield projects

5 Nov 2025

Computer Modelling Group (CMG) has partnered with NVIDIA to accelerate its reservoir simulation software, as energy companies seek faster and more detailed modelling to support carbon storage, geothermal and conventional oil and gas projects.

The partnership, announced on November 4, integrates NVIDIA’s accelerated computing platform into CMG’s STARSTM reservoir simulation software. The companies say the upgrade delivers significant performance gains, allowing complex subsurface models that once took hours or days to run to be completed much more quickly.

Reservoir simulation is a core tool in energy development, used to model how fluids move underground and to guide decisions on drilling, carbon dioxide injection or heat extraction. Faster simulation allows engineers to test more scenarios and adjust development plans with greater precision.

The collaboration comes as energy producers face tighter climate rules and a more diverse energy mix. Carbon capture and storage projects and geothermal developments require detailed modelling of underground formations, often under strict time and cost constraints. CMG says improved computing performance can help make such projects more viable.

“Leveraging NVIDIA accelerated computing offers CMG a platform to innovate at the intersection of numerical simulation, AI, and high-performance computing,” said Pramod Jain, CMG’s chief executive.

The updated STARSTM platform can be deployed either on cloud infrastructure or on local systems, giving customers flexibility over how they balance speed, cost and data control. CMG said this would suit both large energy companies and smaller developers working with limited computing resources.

The move reflects a broader shift in the energy sector towards high-performance computing and digital tools to improve project design and execution. Faster simulation is increasingly seen as a competitive advantage, particularly as companies invest in lower-carbon technologies alongside traditional oil and gas production.

CMG said early users in North America and the Middle East were already applying the enhanced software in live projects, reporting more agile workflows and improved insight into subsurface behaviour.

As energy systems evolve, the company is positioning advanced simulation as a central tool for planning and risk management, with computing speed becoming an increasingly valuable asset.
