Abstract

A new type of capillary end effect in oil and gas reservoirs due to heterogeneous wettability has been justified. This type of capillary end effect is not related to the contrast of reservoir rock permeability or porosity. Nonlinear fliud flow in the layers with heterogeneous wettability has been established experimentally. The mechanism of this phenomenon is due to the new type of capillary end effect.
