Abstract

It has become common to hydraulically fracture a naturally fractured formation to increase the well’s production potential. Since the mass transfer between fractured network and hydraulic fracture is much higher than that from matrix to fractures, the hydraulic fracture-fracture network interporosity flow parameter is much higher that that of matrix-fracture network. As a result, the transition period behavior from naturally fractured to homogeneous takes place before radial flow regime during the early bilinear, linear or elliptical (birradial) flow regimes. The purpose of this paper is to provide expressions by both conventional analysis and TDS technique for characterizing the naturally fractured parameters when the transition period interrupts the response of an infinite-conductivity fracture. The developed expressions for both methodologies were satisfactorily tested with simulated examples.
