In many practical cases the Radial Flow Pressure Diffusion is getting 

reservoir fluid flow created by well is getting aligned with a radial direction towards or away from well.

This type of reservoir fluid flow is called radial fluid flow and corresponding pressure diffusion models provide a diagnostic basis for pressure-rate base reservoir flow analysis.

The radial flow can be infinite acting or boundary dominated or transiting from one to another.

Although the actual reservoir fluid flow may not have an axial symmetry around the well-reservoir contact or around reservoir inhomogeneities (like boundary and faults and composite areas) but still  in many practical cases the long-term correlation between the flowrate and bottom-hole pressure response can be approximated by a radial flow pressure modelevolving towards pressure stabilization and can be efficiently analyzed using the steady-state flow model.
