Hot dry rock geothermal potential of Roosevelt Hot Springs area: review of data and recommendations [PDF]

, 1981
The Roosevelt Hot Springs area in west-central Utah possesses several features indicating potential for hot dry rock (HDR) geothermal development. The area is characterized by extensional tectonics and a high regional heat flow of greater than 105 mW/m ...

Sequential coupling thermal-hydro-mechanical model for multiple cluster of fracturing network fracturing in dry hot rock reservoir

Youqicang pingjia yu kaifa, 2022
In order to solve the problem that thermal-hydro-mechanical coupling model of hot-dry-rock（HDR） reservoir fracturing is complex and it is difficult to achieve large-scale multiple cluster of fracturing network simulation, a sequential coupling simulation

Fracture Network Characterization and Thermal Performance Prediction in Enhanced Geothermal Reservoirs Using Covariance Matrix Adaptation and Embedded Discrete Fracture Model

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract Fracture networks constitute essential conduits for fluid and heat transport in enhanced geothermal systems (EGSs), yet their characterization is challenging due to the inherent geological complexities. This study develops an integrated inversion framework for effective fracture network characterization.

Roosevelt Hot Springs/hot-dry-rock prospect and evaluation of the Acord 1-26 well [PDF]

, 1983
Previous hot, dry rock (HDR) geothermal resource evaluation efforts have identified the Roosevelt Hot Springs KGRA as a prime HDR target. The size of the HDR resource is estimated to be at least eight times larger than the adjacent hydrothermal resource.

Seasonality Controls Biogeochemical Shifts in Oxygen, Carbon, and Nitrogen Along a 12‐m, 54 hr‐Long Hyporheic Flowpath

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Hyporheic exchange is critical to river corridor biogeochemistry, but decameter‐scale flowpaths (∼10‐m long) are understudied due to logistical challenges (e.g., sampling at depth, multi‐day transit times). Some studies suggest that decameter‐scale flowpaths should have initial hot spots followed by transport‐limited conditions, whereas others

A Numerical Investigation of the Hazardous Injection Area of Induced Earthquake during Hydraulic Fracturing

Shock and Vibration, 2021
Hot dry rock (HDR) geothermal energy has many advantages, such as being renewable, clean, widely distributed, and without time and weather limitations. Hydraulic fracturing is usually needed for the exploitation of HDR geothermal energy.

Research Progress and Technical Challenges of Geothermal Energy Development from Hot Dry Rock: A Review

Energies
The reserves of hot dry rock (HDR) geothermal resources are huge. The main method used to develop HDR geothermal resources is called an enhanced geothermal system (EGS), and this generally uses hydraulic fracturing.
