Structure of the low permeable naturally fractured geothermal reservoir at Soultz

Using Automated, High-Precision Repicking to Improve Delineation of Microseismic Structures at the Soultz Geothermal Reservoir

Prediction of Naturally Fractured Reservoir Performance using Novel Integrated Workflow

Generation of naturally fractured reservoir subsurface fracture maps and prediction its production potential are considered complex process due to insufficient data available such as bore hole images, core data and proper reservoir simulator model. To overcome such shortcomings, the industry has relied on geo-statistical analyses of hard and soft data, which are often referred to as static data...

Impact of Induced Thermal Stresses During Circulation Tests in an Engineered Fractured Geothermal Reservoir Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France

Impact of Induced Thermal Stresses during Circulation Tests in an Engineered Fractured Geothermal Reservoir: Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France — The wider concept of hot fractured rock geothermal energy is put forward to overcome the natural limitations of classic geothermal fields. A suite of numerical modules based on a disc...

Investigation of Underground Gas Storage in a Partially Depleted Naturally Fractured Gas Reservoir

In this work, studies of underground gas storage (UGS) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. Reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. Effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. Results show...

A Design Nomogram for a Horizontally-Fractured Geothermal Reservoir to determine the Production Temperature

T.C. Ekneligoda Abstract: The paper presents a graphical technique for the rapid analysis of the complex, nonlinear equation that describes the variation of the production temperature of a horizontally-fractured geothermal well. The nomogram presented for the evaluation of the production temperature incorporates the mass flow rate, fracture width, fracture length, number of conductive fractures...
