Tempest MORE is a modern full field, full physics next generation simulator. Optimised for large models, and providing parallel simulation as standard, engineers benefit from fast simulation. Deck setup is simplified by support for standard grid formats, table input for well historical, trajectory and schedule data and graphical event editing. MORE’s Smart Operations allows for realistic specification of reservoir management as the simulation runs into the prediction phase. MORE supports both black oil and equation of state simulation within the same program, only the fluid description needs changing to switch modes. The same program also supports thermal/steam simulation and coal bed methane modelling. Physical processes such as dual porosity/permeability, polymer injection, CO2 injection, fractured wells and near well bore effects are all modelled.
