Rwenzori springs refer to hot and cold mineralized springs around Rwenzori Mountains. A chemical sampling campaign was undertaken as part of the GEOTHERM programme, a technical cooperation project between the Government of Uganda and Germany. The geochemi
The Konocti Bay Fault Zone (KBFZ), initially regarded by some as a promising liquid dominated hydrothermal system, has been a disappointment as a geothermal prospect. Five exploratory wells have been drilled in the vicinity of the KBFZ, but none of them a
Understanding the processes that enhance fluid flow in crustal rocks is a key step towards extracting sustainable thermal energy from the Earth. To achieve this, geoscientists need to identify the fundamental parameters that govern how rocks respond to st
At the Raft River Geothermal Area in south central Idaho's Raft River Valley, the Idaho National Engineering Laboratory (INEL) is investigating practical uses for moderate temperature geothermal fluids. This research is sponsored by the Department of Ener
Electrical and hydraulic conductivities in the reservoir environment can vary over many orders of magnitude over very small distances, while human vision is limited to perception of a Cartesian space in which the perceptual scales in all directions are co
Two extreme arguments have been used in the past to explain the origin of chlorine in high temperature geothermal fluids, namely, chlorine is continuously leached from the surrounding country rock, or it is of magmatic origin. Two further variations are t
An equilibrium state of geothermal fluid in fractured and/or porous reservoirs is discussed, when classic hydrostatic equation, as corollary of Darcys law, gives wrong results. It is shown, that generally hydrostatic equation must include addition term,
A comparative assessment of five potential hydrothermal-magma sites for this facet of the Thermal Regimes part of the CSDP has been prepared for the DOE Office of Basic Energy Sciences. The five sites are: The Geysers-Clear Lake, CA, Long Valley, CA, Rio Grande Rift, NM, Roosevelt Hot Springs, UT, and Salton Trough, CA. This site assessment study has drawn together background information (geology, geochemistry, geophysics, and energy transport) on the five sites as a preliminary stage to site selection. Criteria for site selection are that potential sites have identifiable, or likely, hydrothermal systems and associated magma sources, and the important scientific questions can be identified and answered by deep scientific holes. Recommendations were made.
Possibility of carbon sequestration in high temperature liquid dominated geothermal reservoirs is analyzed by means of reservoir simulations. Several different simulations with differing carbon dioxide injection rates and injection pressures were conducte
The use of nonreactive isotopic tracers coupled to a full thermal-hydrological reservoir simulation allows for an improved method of investigating how reservoir fluids contained within matrix and fractures contribute over time to fluids produced from geot
In September of 2010, GreenFire Energy received a US Department of Energy grant to attempt a real-world trial of CO2-based geothermal energy (CO2G) at a site on the St. Johns-Springerville CO2 Dome near the Arizona-New Mexico border. Though CO2G was propo
The Los Azufres Geothermal Field in Mexico is a typical high temperature hydrothermal system along convergent plate boundaries. Models of high-temperature-pressure experiments and geochemical simulation calculations have been performed. Natural rock sampl
