The objective of this study is to present the pressure build-up behavior of a well located in a naturally fractured reservoir and produced at a constant well-bore pressure. The flow period response is presented to preserve continuity. A fractured reservoir means a reservoir consisting of 2 systems of porosity and permeability: a primary system which is the rock matrix, and whose properties were determined by the depositional environment, and a secondary system of fissures of induced properties. The latter is usually assumed to be the result of post depositional geologic events. Furthermore, the properties of a naturally fractured reservoir are such that the storage properties are associated with the matrix while the conducting properties are due largely to the fracture network. This study considers the model with unsteady state fluid transfer from matrix to fracture. 19 references.
