What’s New at CMG
Ongoing development focused on solver performance, numerical robustness, and extending modelling capability for increasingly complex reservoir and energy systems.
Driven by Increasing Model Complexity
Solver Performance & Parallelization
Enhancements to solver technologies focus on improving convergence behavior and execution time in models containing difficult non-linear complexities and large problem/system sizes.
- Integration of GPU-accelerated solver capabilities. Read more about the external benchmarking of IMEX on GPU
- 1.81x speedup in GEM between 2025.11 and 2026.11
- 1.3x speedup in Flexwell simulations
- Improved parallel scalability and speed when using distributed compute (MPI-based approaches)
- More efficient handling of tightly coupled well and reservoir equations
Advanced Physical Modelling
Updates expand the ability to model complex physical interactions where phase behavior and component coupling are critical.
- Extensions to equation-of-state, flash, and flow formulations to better capture phase interactions (including Cubic Plus Association – CPA – effects) in multi-component and solvent systems
- Improved handling of multi-stream injection processes, including automatic treatment of mixture properties and thermodynamic states
- Advanced 4-phase thermodynamic modelling to capture solvent-rich phase behavior in thermal recovery processes
- Improved representation of geochemical reactions, including pH-dependent reaction rates and mineral interactions
Energy Transition Modelling
Enhancements extend modelling capabilities for systems where geochemistry and fluid composition evolve over time.
- Direct support for externally defined reaction systems (e.g., laboratory-derived reaction formats)
- Enhanced boundary condition handling for multi-phase, multi-component flow across model limits
- Improved treatment of variable composition injection streams in carbon storage scenarios
- Improved subsurface hydrogen-storage using new Double and Extended Monod Kinetics
Integrated Reservoir-Surface Modelling
Updates improve the consistency of thermodynamic and flow calculations across coupled reservoir and surface domains.
- Improved handling of thermodynamic properties where enthalpy-based calculations are required
- Better alignment between reservoir conditions and surface network calculations
- Faster model and scenario setups through updated import workflows and wizards
- Increased flexibility in defining system-wide constraints and flow conditions
- New erosion modelling in CoFlow using API 14E and Salama methodologies
Model Handling & Workflow Efficiency
As model size increases, non-simulation tasks (loading, editing, extraction) may become bottlenecks. Recent updates target these areas directly.
- Improved load/save performance for large datasets, including better memory management during initialization
- More efficient grid refinement operations, particularly in regions with dense well activity
- Optimized submodel extraction workflows for localized studies within large domains
- Introduced new Load Summary Pane in Builder highlighting any errors or warnings for faster insights
- Direct import and export of OSDU compliant RESQML models
