T2SOLV is an enhanced package of solvers for the TOUGH2 family of codes. T2SOLV includes all the 'reconditioned Conjugate Gradient (PCG) solvers ised in T2CG1, the current solver package, as well as XBAND, a new direct solver, and DLUSTB, a PCG ;olver based on the BiCGSTAB method. 4dditionally, T2SOLV includes the D4 grid number,ng scheme and two sets of preprocessors. Results From test problem...

This paper is an update of an earlier supply analysis, He, et al., (2013), of low-temperature utilization of geothermal resources using geothermal district heating and cooling systems. Along with the use of identified hydrothermal resources, it updates the supply curve for direct-use utilization using undiscovered hydrothermal resources and near-hydrothermal EGS resources. It also incorporates ...

Variations in temperature and salinity in hypersaline liquid-dominated geothermal systems like the Salton Sea Geothermal System (SSGS) tend to be correlated such that liquid density is relatively constant in the system. The tendency toward small density variations may be due to connectivity with a surrounding regional aquifer at multiple depths in the stratigraphic column. We present numerical ...

The research was conducted at the Geothermal Company Energy Lx Area. area includes three well pads of geothermal power plants, namely X1, X2, and X3, which are stratigraphically composed quaternary volcanic rocks. Based on geochemical data pad, it shows that chloride type fluid is in equilibrium/partial equilibrium with reservoir temperature range 230 – 300°C from silica Na-K geothermometer ana...

Geothermal resources used to generate power are complex systems. The hydrother‐ mal, high-temperature geothermal reservoirs, which are the only commercially exploited ones up to now, are usually found several (1-3 km) kilometers deep, and they should be exploited in a sustainable way. Thus, in order to support decisions on optimal exploitation policies, efforts focused on investigating how rese...

The main reservoir in the Dixie Valley geothermal field of Nevada is hosted in fractured Jurassic rocks within the hanging wall of the Stillwater fault. Within the Jurassic sequence, at least four major stages of alteration related to the fault system can be identified. The paragenetic sequence from oldest to youngest consists of Stage I) biotite-potassium feldspar veins, and epidote-chlorite-c...
