Chlorite, Biotite, Illite, Muscovite and Feldspar Dissolution Kinetics at Variable pH and Temperatures up to 280 deg C

Feb 24, 2017
19.93 MB
Publicly accessible
Chemical reactions pose an important but poorly understood threat to EGS long-term success because of their impact on fracture permeability. This report summarizes the dissolution rate equations for layered silicates where data were lacking for geothermal systems. Here we report ...

Chemical Impact of Elevated CO2 on Geothermal Energy Production

Jan 01, 2013
2.13 MB
Publicly accessible
Numerical simulations have shown that the use of supercritical CO2 instead of water as a heat transfer fluid yields significantly greater heat extraction rates for geothermal energy. If this technology is implemented successfully, it could increase geothermal energy production and...

Chlorite Dissolution Rates From 25 to 275 degrees and pH 3 to 10

Sep 27, 2013
91.48 kB
Publicly accessible
We have calculated a chlorite dissolution rate equation at far from equilibrium conditions by combining new data (20 experiments at high temperature) with previously published data Smith et al. 2013 and Lowson et al. 2007. All rate data (from the 127 experiments) are tabulated in...

A Thermal-Hydrological-Chemical Model for the EGS Demonstration Project at Newberry Volcano, OR

Jan 30, 2012
Size unavailable
Publicly accessible
Newberry Volcano in Central Oregon is the site of a Department of Energy funded Enhanced Geothermal System (EGS) Demonstration Project. Stimulation and production of an EGS is a strong perturbation to the physical and chemical environment, giving rise to coupled Thermal-Hydrologic...
