The approximation technique addresses the problem of two-dimensional flow of a slightly compressible fluid into a well bisecting a plane vertical fracture. The solution sought is subject to appropriate boundary and initial conditions. Here Ψis the flow potential, P + ρgH(x̄,ӯ) with H(x̄,ӯ) being vertical height above a … See more Pseudo-steady state (PSS) flow occurs during the late time region when the outer boundaries of the reservoir are all no flow boundaries.

The clockwise specifier (c) means only the flows that are moving clockwise in our loop, while the counter-clockwise specifier (cc) is only the flows that are moving counter-clockwise. This adjustment doesn't solve the problem, since most networks have several loops.
