Bilinear Fracture Flow

Bilinear fracture flow occurs in hydraulically fractured wells when the conductivity of the fracture is finite. In this flow regime, two types of linear flow occur, one from the matrix to the fracture and one from the fracture to the wellbore. This is usually evident in long fractures (which are hard to prop open effectively) or in natural fractures (which contain fracture fill minerals).
