Image logs and the continuous coring of 8 geothermal wells in the Central Upper Rhine Graben (URG) are used for the structural characterization of 3 geothermal reservoirs at Soultz-sous-Forets, Rittershoffen and Illkirch ...

The presence of natural fractures in a porous medium strongly influences the fluid flow path. The complex geometric characteristics of the fracture network create preferential channels that change the permeability of the ...

Naturally fractured reservoirs are complex systems to characterize and predict. It is important to establish some basic criteria to identify when fractures are an important element in reservoir performance and also recognize ...

Many reservoirs consist of fully saturated rock masses containing a very complex natural fracture network. In such cases a decrease in the fracture fluid pressure reduces its aperture due to an increase in the effective ...

This work aims to apply a sensitivity analysis to determine the influence of natural fractures in a cross section of rock reservoir cell, assessing the equivalent permeability of the medium. Using finite elements with high ...

Hydraulic Fracturing is a widely used method for enhancing oil exploitation in petroleum industry. In this method, some artificial fractures are induced in the reservoir by fluid injection and the overall rock permeability ...
