Journal ArticleDOI
A coupled thermo-hydro-mechanical modeling of fracture aperture alteration and reservoir deformation during heat extraction from a geothermal reservoir
TL;DR: In this article, the authors performed coupled Thermo-Hydro-Mechanical (THM) simulations using a robust code called Finite Element for Heat and Mass Transfer (FEHM) for a 3D domain with a single fracture connecting the injection and production wells.
Journal ArticleDOI
Lessons learned from the pioneering hot dry rock project at Fenton Hill, USA
TL;DR: The Hot Dry Rock project at Fenton Hill, New Mexico as discussed by the authors was the first attempt to produce usable energy from the heat of the earth, conducted from 1970 to 1995 at the Los Alamos National Laboratory.
Journal ArticleDOI
Pathline tracing on fully unstructured control-volume grids
TL;DR: A method for calculating flow streamlines or pathlines from a finite-volume flow solution that agrees well with established semianalytical methods and produces physically realistic results on fully unstructured three-dimensional grids is presented.
Journal ArticleDOI
Investigation of permeability alteration of fractured limestone reservoir due to geothermal heat extraction using three-dimensional thermo-hydro-chemical (THC) model
TL;DR: In this paper, the authors investigate the porosity alteration during geothermal heat production from carbonate reservoirs using coupled thermo-hydro-chemical (THC) capabilities for a three dimensional domain.
Journal ArticleDOI
Fracture transmissivity evolution due to silica dissolution/precipitation during geothermal heat extraction
TL;DR: In this paper, the authors present thermo-hydro-chemical simulations of silicic geothermal reservoirs over ∼20-year durations, showing that initial permeability heterogeneity influences reservoir response significantly only when the correlation lengths are of the order of 1/10th of the fracture size or more.
