- the dominant part of wellbore and reservoir pressure variation is usually radial-flow or linear-flow and the two represent the basis for Pressure diffusion analysis
- in most practical cases the long-term correlation between the flowrate and bottom-hole pressure response can be approximated by a radial flow pressure model
