STARS - Advanced Processes & Thermal Reservoir Simulator
STARS is the undisputed industry standard in thermal reservoir simulation and advanced recovery processes. Reservoir engineers use STARS to simulate changes to the reservoir based upon fluid behaviour, steam or air injection, electrical heating or chemical flooding.
- Modelling of dispersed components and simulate formation of emulsions and foams, and predict asphaltene precipitation/deposition
- Accurately model the physics of all in-situ recovery processes
- Multi-scale modelling from core floods to field-scale
- Increase confidence in field development plans and support capital expenditures
- Design accurate SAGD well pairs
- Seamless integration with CMOST for rapid, accurate history matches and uncertainty analysis, while leveraging limited engineering time
STARS is a thermal, K-value compositional, chemical reaction and geomechanics reservoir simulator ideally suited for advanced modelling of recovery processes involving the injection of steam, solvents, air and chemicals. The robust reaction kinetics and geomechanics capabilities make it the most complete and flexible reservoir simulator available.
Heavy Oil & Thermal - STARS enables the simulation of complex in-situ processes by representing the physical processes as a series of reactions between the various fluid and solid components in the reservoir – those reactions can be tuned by the reservoir engineer to match the laboratory experiments and field results.
Chemical Enhanced Oil Recovery (EOR) - STARS simulates the wellbore treatment procedures required to evaluate the effectiveness of chemical additives used in chemical EOR processes. Globally, STARS is also the most widely used foam simulator as it is the only commercial simulator to mechanistically model the complex physical processes involved in foam flooding.
Wellbore Completions - FlexWell models a variety of wellbore completion configurations, including concentric wellbores and flow-control devices, while properly accounting for well trajectories. Engineers are able to calculate wellbore pressure gradients to determine its impact on reservoir simulation inflow and outflow.
Geomechanics - STARS includes a rigorous, iteratively-coupled 3D geomechanics module, as well as, integration with third party packages for modelling subsidence, compaction and dilation behaviour that occurs during thermal or advanced processes recovery method.
