Interpretation of Displacement Data Obtained from Unsteady-State Radial Fluid Flow Systems

D07 INTERPRETATION OF DISPLACEMENT DATA OBTAINED FROM UNSTEADY-STATE RADIAL FLUID FLOW SYSTEMS Abstract 1 This paper presents the practical interpretation formulae which can be used for determination of the relative permeability data obtained from immiscible fluid displacement experiments. The derived formulations are convenient to determine the relative permeability curves the Leverett functions and the displacement efficiency. The results were validated by using the laboratory data obtained by lateral immiscible fluid displacement in horizontal porous disks. For this purpose the convenient interpretation formulae elaborated and demonstrated by the authors (1998 2002) earlier for determination of relative permeability from unsteady-state twophase linear
