INTERPRETATION BY NUMERICAL MODELLING OF CHANGES OF FRACTURE SYSTEM HYDRAULIC CONDUCTIVITY INDUCED BY FLUID INJECTION

Distinct element modelling of naturally fractured reservoirs is used to investigate changes of hydraulic conductivity induced by fluid injection. General conclusions are drawn relating to the effects of uniform changes of pore pressure on conductivity anisotrooy in connected joint systems. The influence of cross-cutting discontinuous joints on the conductivity of the joints against which they terminate is emphasized. Results from a two dimensional model are related to the observed performance of a granite geothermal reservoir.
