Numerical simulator for the coupled model of wells and fractured reservoirs

Abstract

This study presents a numerical simulator for the coupled model of wells and reservoirs, which is being developed. The simulator is capable of transient flows along directional wells and intersecting multiple planar structures based on the concept of discrete fracture network models. Comparisons with analytical and numerical solutions obtained using reference codes successfully validated the simulator of this study. An application to the hypothetical coupled problem of a directional production
well intersecting multiple planar structures was demonstrated, in which a steam cap was generated at the top of the reservoir while producing for 300 days. The flowing enthalpy at the wellhead varied depending on the temporal variation in the flow rate in each feed zone. The simulator will be further extended and enhanced based on the requirements of specific problems and suggestions from scholars in open communities.
