THE eFFECTS OF ADSORPTION ON INJECTION INTO GEOTHERMAL RESERVOIRS
The effects of an adsorbing phase on the injection of liquid and eventual production of vapor from a lowporosity, vapor dominated geothermal reservoir was studied. The magnitude of delay caused by adsorption, diffusion partitioning, preferential partitioning, and permeability variation were compared. Results were then compared to measured tracer production data at the Geysers to determine the m...
متن کاملCharacterization of Rock Pore Features in Geothermal Systems Using Small Angle Neutron Scattering (sans)
Enhanced Geothermal Systems (EGS) are engineered reservoirs created to economically extract heat from low permeability and/or porosity geothermal resources. Existing geochemical reactive transport models for such systems lack essential data on the structure of the pore systems in geothermal reservoirs, and how they evolve in the relevant ranges of temperature, pressure, composition, and length ...
متن کاملA Capillary Pressure Model for Geothermal Reservoirs
Abstract Steam-water capillary pressure is often either ignored or determined artificially in geothermal reservoir engineering. However steam-water capillary pressure plays an important role in geothermal reservoir performance and may not be substituted by air-water capillary pressure. To this end, preliminary mathematical models have been developed to calculate drainage and imbibition steam-wa...
متن کاملThe Fluid Inclusion And Mineralogic Record Of The Transition From Liquid- To Vapor-Dominated Conditions In The Geysers Geothermal System, California
Fluid-inclusion measurements and textural relationships demonstrate that coarse-grained quartz and calcite from the upper part of The Geysers thermal system formed during the transition from liquid-dominated conditions to the modern vapor-dominated regime. The most diagnostic characteristics of these transition assemblages are: 1) evidence of quartz dissolution; 2) contemporaneous trapping of h...
متن کاملHeavy metal contamination from geothermal sources.
Liquid-dominated hydrothermal reservoirs, which contain saline fluids at high temperatures and pressures, have a significant potential for contamination of the environment by heavy metals. The design of the power conversion cycle in a liquid-dominated geothermal plant is a key factor in determining the impact of the installation. Reinjection of the fluid into the reservoir minimizes heavy metal...
