oa On the Importance of Correct Inclusion of Capillary Pressure in Reservoir Simulation

Capillary pressure is frequently omitted from large scale reservoir simulation, rationalized by arguments that may not always be valid. A number of papers have shown that correct modelling of capillary pressure may be as important for the simulation result as properly accounting for relative permeabilities. Especially in strongly heterogeneous modale it is important to study the sensitivity to all petrophysical parameters before simplifications are introduced in the simulation model.
