INTRODUCTION Stimulation of geothermal reservoirs, especially hot fractured rock or enhanced geothermal systems (EGS) reservoirs, has usually relied on injection of thin or low viscosity fluids (e.g. water) at pressures Fractured Basement Reservoir Characterization for Fracture Distribution, Porosity and Permeability Prediction* Marie Lefranc. 1, Sherif Farag1, Laurent Souche1, and Agnes Dubois1 .

Fractured Reservoir In naturally fractured reservoirs, several sophisticated models were developed to describe the pressure response in dual porosity system. This section reviews the analytical and numerical models concerning well test analysis in this type of reservoirs. The discovery of the first fractured reservoir was in ing capacity of a naturally fractured reservoir is governed by matrix-fracture fluid transport capacity, which is called interporosity flow. To describe flow in naturally fractured reservoirs, double pomsity model has been widely used. Fig. 1.1 shows the schematic of a naturally fractured reservoir and its double porosity idealiza- tion. 4. Introduction to Reservoir Simulation 5.

Reservoir Fluid Characterisation Supplementary scripts used at the Montanuniversitat up to the retirement In naturally fractured reservoirs, the matrix pore volume, therefore the matrix porosity is reduced as a result of large reservoir pressure drop due to oil production. This large pressure drop causes the fracture pore volume, therefore fracture porosity, to increase. Fractured reservoirs are those in which fractures have caused a significant increase in total permeability. Carbonate reservoirs, tight sandstone reservoirs, basementreservoirs and shale reservoirs are all commonly fractured, and present significant challenges to petroleum geologists. Fractured reservoirs are those in which fractures have caused a significant increase in total permeability. Carbonate reservoirs, tight sa
