Adaptive Hierarchical Fracture Model for Enhanced Geothermal Systems
Multiscale Modeling & Simulation, 2016Summary: In enhanced geothermal systems, cold working fluid (usually water) is injected into a fractured reservoir to enhance the efficiency of the power plant by increasing the conductivity of existing fractures and by creating new ones. For the modeling of single phase flow and transport in such dynamically changing fractured reservoirs, a new ...

Fracture reactivation for permeability enhancement in geothermal systems
2020<p>While the deep granitic basement in the Upper Rhine Graben is currently being exploited as a geothermal reservoir at numerous geothermal sites, the Permo-Triassic sandstones that lie directly above the granite are critical to continued regional hydrothermal convection.

Our previous study (Song et al., 2018) proposed a novel enhanced geothermal system (EGS) with multilateral wells and demonstrated that it had greater heat extraction performance than double-well EGS.

Magnetotelluric monitoring of permeability enhancement at enhanced geothermal system project
Geothermics, 2017Abstract Magnetotelluric (MT) data were collected across the Habanero Enhanced Geothermal System (EGS) project in the Cooper Basin, South Australia. A baseline regional MT survey consisting of two profiles were collected to delineate subsurface resistivity structure.

Beyond Hydrocarbon Extraction: Enhanced Geothermal Systems
2016There are many forms of energy that exist subsurface. Mining typically extracts minerals that are energy rich and processes them to produce electricity. The oil and gas industry extracts hydrocarbons with high energy content that are suitable for energy production.

Stress magnitudes in the Basel enhanced geothermal system
International Journal of Rock Mechanics and Mining Sciences, 2019Abstract This paper presents the results of an evaluation of stress magnitudes in the granitic EGS reservoir in Basel, Switzerland. The profile of minimum principal horizontal stress, Shmin, is constrained by hydraulic tests, but the magnitude of the maximum horizontal principal stress, SHmax is uncertain.

Formation of enhanced geothermal system provides flow and heat transfer paths for heat extraction in HDR (hot dry rock). Based on the local thermal non-equilibrium theory, the THM(thermal-hydraulic-mechanical) coupling is established to describe the ...
