...Initial Screening Geothermal gradient is the first key criterion for identifying wells that are suitable for geothermal heat extraction. However, the geothermal gradient value does not directly determine the feasibility of electricity production from geothermal energy. Power generation using...

...-effectiveness of adopting geothermal production in low to medium enthalpy systems by either repurposing existing oil and gas wells or by co-producing thermal and fossil energy. The workflow introduces an automated and intrinsically secure decision-making process to convert mature oil and gas wells...

... in geothermal energy production. The IHFC has stated that it plans to consider adding more heat flow-related data such as heat calculations from sensors on airborne and space devices (e.g., drones, airplanes, satellites). These would be available in a separate database. The original global heat flow...

... Abstract Geothermal District Heating (GDH) doublets in the Central part of the Paris Basin, particularly in the Capital City suburban areas, face two major concerns: The replacement of aging and declining, when not damaged, well infrastructures and productive/injective capacities; GDH...

... resulting from production and thus optimize production. This allows us to control the geothermal producing zone and produce more efficiently and at higher output. Further, with geothermal reservoirs induced seismicity is often an issue and together with microseismic monitoring, EM will allow for a swift...

... producing over 1500MW of electricity. All the geothermal energy production discussed above, whether direct use or used for electricity production, is from naturally occurring hydrothermal reservoirs that are located in areas of tectonic or volcanic activity. Not unlike conventional oil and gas...

... flow measurements are the average production over one year for 27 different wells. Four of these wells were drilled near to or outside of the geothermal field and are characterized by production rates of < 5kg/s. The distribution of the data is plotted on Figure 1. drilling location reservoir...

... production at Brawley and Coso in California. We resort to thermohydro-mechanical modeling and used measurements of surface deformation to validate our simulations. We find that thermal stresses induced by fluid injections for geothermal energy production play an important role in either triggering...

... ABSTRACT Highly saline fluid is produced from a sandstone reservoir (4.4 km depth; 150 °C) at the geothermal in-situ laboratory in Groß Schönebeck (Germany). During several production and injection tests samples from solid-, liquid-, and the gaseous phase have been collected from the depth...

.... The output models were used as input for the heat flow simulations and enthalpy production evaluation, which resulted in more realistic scenarios compared to the layer cake models commonly used in geothermal simulations. The reservoir was built in a grid that covers an area of 113.8 sq-km (1.225 E6 sq-ft...

... Abstract Tracer test is a strong tool that is used to understand the connectivity between injection and production wells in geothermal reservoirs. It is essential to design and implement a tracer test for particular reservoir properties. Inappropriate tracer tests, might cuase wrong reservoir...

... objective of this work is to study the impacts of horizontal permeability anisotropy inferred from pressure-interference tests on geothermal-doublets performance. A theoretical relation between the measured directional permeability and the elements of the permeability tensor are presented. In a case study...

...ABSTRACT ABSTRACT Geothermal projects are rapidly developing in Continental Europe to provide an alternative energy source. These projects typically involve a doublet of a producer and injector well, which are typically vertical wells drilled with minimal measurement technology. We discuss how...
