PARAMETRIC STUDY WITH GEOFRAC: A THREE-DIMENSIONAL STOCHASTIC FRACTURE FLOW MODEL

摘要

This paper presents results of a parametric study using GEOFRAC. Recent developments in GEOFRAC allow the user to calculate the flow in a fractured medium in a geothermal context. Both the fracture- and the flow model have been tested, and a simple parametric study was conducted in order to check the sensitivity of the output. After a brief introduction to GEOFRAC the paper discusses the results of the simulations and attempts to explain how aperture, width and rotation (orientation distribution) of the fractures influence the resulting flow rate in the production well.
