Simulate Newtonian Darcy three phase (gas/oil/water) flow near the wellbore in three dimensions.


The Olga ROCX module is a dynamic reservoir model designed to model transient flow rates and pressures near the wellbore, where transient events occur on the same time scale as the wellbore and pipeline transients. The Olga simulator sends wellbore pressure information to the ROCX module, which then sends flow rates for each phase back to the Olga simulator.
