- Thermal chemical reactions
Chemical reactions can now be modeled. Reactions are currently restricted to thermal simulations but can involve any fluid component. The reaction rate term can be defined as a function of the concentration of the reactants. An additional reaction rate term, based on an equilibrium condition, can also be used. This allows reactions to be used instead of the flash so the nonequilibrium effects can be modeled (e.g., noncondensable gas).
- Automated hybrid parallel
When INTERSECT high-resolution reservoir simulator is launched, the dataset is analyzed to determine the best combination of multiple page interface (MPI) processes and threads for the functionality required and the number of cores specified.
- Simplified region mapping
INTERSECT simulator uses the region mapping mechanism to map models (fluid models, rock models, and equilibrium models) to regions in the reservoir grid. A new, simplified region mapping schema with a tabular format offers improved usability while supporting existing functionalities. When assigning models to nongrid, such as a compositional model to a separator, users can now do so directly without extra actions, which greatly enhances usability. This new schema is supported in Petrel 2018.2.
The schema of a conventional well model (as opposed to multisegment well models) is simplified to improve usability. This new schema is supported in Petrel 2018.2.
