Numerical Simulation of a Tracer Test at Dixie Valley, Nevada
A tracer test was conducted at the Dixie Valley, Nevada, geothermal reservoir using fluorescein. Four of 9 production wells showed fluorescein breakthrough during the first 200 days of the test. Reconstructed fluorescein return curves are presented that correct for the thermal decay of the tracer assuming an average reservoir temperature of 227°C. In order to examine the feasibility of using nu...
متن کاملUnmixing of Aviris Hyperspectral Data from Dixie Valley, Nevada
The high temperature hydrothermal convection system underlying northwestern Dixie Valley, Nevada, is probably responsible for the development of certain geobotanical anomalies in the area. A large “die-off’ of Bailey’s greasewood (Sarcobatus baileyi) has been observed over the last several months and appears to be related to activity that preceded the appearance of a new fumarole. AVIRIS (Advan...
متن کاملDating Sinter Deposits in Northern Dixie Valley, Nevada- the Paleoseismic Record and Implications for the Dixie Valley Geothermal System
A series of fossil spring deposits are exposed along the Dixie Valley fault just south of the producing geothermal field, in an area now characterized by active fumaroles and steaming ground. These deposits are composed of both travertine and sinter that have trapped pollen and other plant material during their formation. Radiocarbon dates on the organic material indicate that the youngest hot ...
متن کاملTectonic Controls on Reservoir Permeability in the Dixie Valley, Nevada, Geothermal Field
To determine factors controlling permeability variations within and adjacent to a fault-hosted geothermal reservoir at Dixie Valley, Nevada, we conducted borehole televiewer observations of wellbore failure (breakouts and cooling cracks) together with hydraulic fracturing stress measurements in six wells drilled into the Stillwater fault zone at depths of 2-3 km. Measurements in highly permeabl...
متن کاملAn Investigation of the Dixie Valley Geothermal Field, Nevada, Using Temporal Moment Analysis of Tracer Tests
The method of analysis of the first temporal moment (mean residence time) of tracer return data was utilized to investigate the swept volume and fluid velocity between pairs of injection and production wells in the Dixie Valley geothermal field. Calculations were made using a spreadsheet program available from the Idaho National Laboratory. Jointly sponsored industry–government research at the ...
