Description

A study of imbibition processes in micromodel geometries that mimic a matrix-fracture system was undertaken. Experiments in glass micromodels and pore network simulation were conducted. It was observed that, at low capillary number values the wetting fluid preferentially invaded the matrix. Two critical capillary numbers were identified, one for the start of penetration in the fracture when the viscosity ratio was much less than one, and another for which the rate of propagation of the front in the fracture is the same with that in the matrix, when the viscosity ratio was greater than one. These critical capillary numbers were … continued below

It was observed that, at low capillary number values the wetting fluid preferentially invaded the matrix.

These critical capillary numbers were well matched with the results of a pore network simulation. We also developed a simplified theory for both critical numbers. Free imbibition in fractured system was investigated an(] compared favorably with pore network simulation. This process first involves the ra.pi(i invasion of the matrix, followed by the subsequent penetration of the fracture.
