Annotation:
The purpose of the article is to continue the topic "Methods of hydrodynamic modeling" in terms of further consideration of techniques for creating an oil saturation field from the J-function, taking into account the contact angles of wettability as a tuning parameter. Actual models show that a change in wettability angles (from physic to philic reservoir type) leads to a change in recoverable oil reserves by more than 15 %. The calculations are based on the assumption about the phase permeability invariance and critical points.
