In recent years the pressure pulse decay technique became a frequent tool for fast and convenient measurement of permeability of tight rocks. The method is superior to conventional steady state method as it is much faster and easier to perform. Few authors considered measurement of matrix and fracture permeabilities by using this technique. In this study a mathematical model for solving the problem of transverse, unsteady compressible fluid flow through fractured whole core was developed. Experimental setup has been constructed to perform pressure pulse decay experiments on whole cores. Based...
