Enhanced geothermal systems (EGS) play a crucial role in the shift from fossil to renewable energy. The Utah Frontier Observatory for Research Geothermal Energy (FORGE) is large-scale experimental EGS that aims overcome setbacks faced by projects, such as economic viability and concerns about induced seismic activity, studying new tools strategies. Four circulation experiments were conducted after completion of well doublet at depth 2.5 km granitoid rock. showed injection production...
Abstract Utah FORGE (Frontier Observatory for Research in Geothermal Energy) is a field laboratory developing, testing, and prototyping technologies that could be adopted commercializing Enhanced Systems (EGS). The principle of developing an EGS to use multiple hydraulic fracturing stages interconnect injection well production – forming the surface area within large heat exchange system. At site, near Milford, Utah, (65° vertical) has been drilled three-stage treatment was carried out at toe...
Abstract The Utah Frontier Observatory for Research in Geothermal Energy (FORGE) is a field-scale enhanced geothermal system (EGS) laboratory studying new techniques and strategies to overcome problems that have halted or hindered the broad application of EGS, including induced seismic activity cost-efficient monitoring EGS reservoirs. During latest stimulation experiments April 2024, we deployed network geophone patches improve (near-) surface network. These consist nine closely spaced...
In this paper, we investigate geothermal exploration and production in 189 hydrothermal projects 42 hot dry rock around the world. The fields for a working system to generate electricity should have elements of heat source, water-saturated porous or fractured reservoir, caprock, transfer pathway, good preservation condition power energy intensity 10–20 MW per km2 within at least 5 area tectonically active region. water steam flow rate is normally larger than 40 L/s with temperature 150 °C...
The efficient exploitation of geothermal energy through enhanced systems (EGS) has been a relevant topic for hot dry rock (HDR) resources. When cryogenic fluid is injected into thermal reservoir, improving heat exchange efficiency key to achieving the optimal HDR. In this paper, granite outcrops from Gonghe Basin were used as testing sample. natural fractures in samples relatively well developed. To simulate long-term injection and production multi-wells situ, physical experiments performed...
Abstract Solid granular proppant particles are widely used in oil and gas development to sustain permeability through fractures after hydraulic stimulation. Similar proppants of interest for geothermal applications where the goal sustaining is same, but harsh environment risks rapid degradation that will reduce fracture permeability. Here, we present conductivity experiments using saw cut granite, tensile fractured aluminum control specimens packed with sintered bauxite ceramic at...
The Raft River Enhanced Geothermal System (EGS) demonstration project incorporated three hydraulic stimulations in well RRG-9 ST1 to improve geothermal production. This study investigated the injectivity index (injection rate divided by injection pressure) increase during long-term into RRG-9-ST1 after from perspective of thermoelasticity. We have used a one-dimensional approximate solution estimate injectivity/aperture change due thermal cooling. inferred aperture vs. square root time falls...
In this study, proppant pillar deformation and stability during the fracturing fluid flowback of channel was simulated with DEM-CFD- (discrete element method-computational dynamics-) coupling method. Fibers were modeled by implementing bonded particle model for contacts between particles. hydraulic fracture-closing period, height decreases gradually diameter increases as closing stress increases. particles could be driven away from flow cause instability pillar. The occur easily large or a...
The availability of rare earth elements from primary resources has come into question in the last two decades. This sparked various government and industry initiatives to examine potential element apart virgin ore bodies. Geothermal fluids are potentially significant sources valuable minerals metals, while co-recovery with geothermal energy production would be an attractive sustainable system. In this work, we give a brief survey data collected on concentrations fluids. A methods...
Summary Waterless fracturing for shale-gas exploitation using supercritical carbon dioxide (scCO2) is both effective and environmentally friendly, has become an extensive research topic. Previous researchers have focused on the chemical physical properties microstructure of sandstone, carbonate, shale caprock, rather than formations. The macroscale mechanical microscale fracture characteristics Wufeng Shale exposed to scCO2 (at greater 31.8°C 7.29 MPa) are still not well-understood. To study...
