Pressure Transient Analysis of Dually Fractured Reservoirs

Abstract

Abstract Dual fracture models are examined as a more realistic alternative to dual porosity models for the representation of naturally fractured reservoirs. A major component of the fracture system is the network of microfracture which by virtue of their lower permeability respond somewhat later than the macrofractures. A delineation of microfracture response versus matrix response is made using the proposed conceptual models. It is demonstrated that the microfractures response may at times be mistakenly attributed to matrix.
