What’s New at CMG
Ongoing development focused on solver performance, numericalrobustness, and extending modelling capability for increasinglycomplex reservoir and energy systems.
Driven by Increasing Model Complexity
Solver Performance & Parallelization
Enhancements to solver technologies focus on improvingconvergence behavior and execution time in models containingdifficult non-linear complexities and large problem/system sizes.
- Integration of GPU-accelerated solver capabilities for selected workflows
- Improved parallel scalability and speed when using distributed compute (MPI-based approaches)
- Updates to linear solver strategies and preconditioning methods for large systems
- More efficient handling of tightly coupled well and reservoir equations
- Greater stability, updated technology, enhanced speed, quick decisions
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
- Enhanced support for dynamic control logic within simulations (e.g., time-dependent constraints, scripted controls)
- Automatic outputs of key process information for solvent enhanced oil recovery systems – reducing time spent in finding and making plots to drive decision
Energy Transition Modelling
Enhancements extend modelling capabilities for systems where geochemistry and fluid composition evolve over time.
- Improved representation of geochemical reactions, including pH-dependent reaction rates and mineral interactions
- 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
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
- Optimize the complete system (facilities + connected reservoirs) with speed and intelligence
Model Handling & Workflow Efficiency
As model size increases, non-simulation tasks (loading, editing,extraction) become significant bottlenecks. Recent updates targetthese 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
- Improved responsiveness in model editing (region selection, property updates, well trajectory adjustments)
