wellSim™ is the simulator family for engineering and training of all well engineering disciplines. By improving insight and understanding of dynamic well behavior, it has the potential to change the ways you plan and drill your complex wells.

wellSim™ utilizes the most advanced downhole simulator, Intellectus™, including dynamic ROP model and coupled Flow and Torque/Drag model. It models the time development of the operations and takes into account dynamic effects like inertia, acceleration and retardation, effects of temperature and pressure changes on the downhole process, etc. A Reservoir model is embedded in the multi-phase hydraulic model for realistic influx behavior. The simulator models dissolved and free-gas realistic during a killing operation. The torque & drag model includes an ROP model for realistic ROP related to WOB based on formation properties.
