Integral method is used to derive solutions for nonlinear pressure diffusion equation. Matrix-blocks with different geometries including slab-shaped, cylindrical and spherical blocks are considered. Solutions have considered effect of fracture pressure depletion regimes and VBSD or multiple blocks. Results are in good agreement with fine grid numerical models. M-F SF for compressible fluids illustrates a transient period and then stabilizes to a constant value at PSS transfer. M-F compressible fluid SF in DP media is a function of fracture pressure depletion regime.
