| Abstract: | In this paper a mathematical model of effective radius for Non-Darcy flow at low velocity in low permeability homogeneous porous media is built up, the Laplace space solution of bottom-hole pressure is derived and new type curves are presented,and are used to analyze a field example. This work plays an important role in the interpretation of early well testing data and the correct discrimination of no-flow boundaries in low permeability oil reservoirs. |
