  	Citation × Citation Citation Abstract Copy Title: Investigations of the Dunes Geothermal Anomaly, Imperial Valley, California: Part 1. Geochemistry of Geothermal Fluid Author: Coplen, T.B. Year: 1974 A geothermal test borehole, DWR Dunes No. 1, was drilled in the Dunes geothermal anomaly by the State of California Department of Water Resources. Water samples from this geothermal system were collected from perforations at 109 and 260 meters depth. These water samples were analyzed for chemical and isotopic composition. These tests indicate that the source of the geothermal fluid is partially evaporated Colorado River water. An investigation of chloride/bromide ratios was used to determine the source of the salt in the geothermal fluid from Dunes. The result may suggest that the salt in the Salton Sea geothermal system and in the Dunes geothermal anomaly is derived from the Colorado River and that this water has not done any leaching or been mixed with water from other sources. It was determined that further geophysical Studies (gravity, seismic refraction, electrical resistivity, and magnetotelluric sounding) are needed to locate the reservoir of geothermal fluid in the Dunes system Title: Investigations of the Dunes Geothermal Anomaly, Imperial Valley, California: Part 1.

Completion and testing. Final report Author: Willits, M.H. Year: 1979 The Fairfax Foster Sutter No. 2 well, located in the East Franklin area of St. Mary Parish, Louisiana, is the first successful test of a geopressured-geothermal aquifer under the Well-of-Opportunity program. The section tested was the MA-6 sand of lower Miocene age which has produced large quantities of gas from the adjacent but structurally separated Garden City field. In the subject well the observed temperature was 270{sup 0}F (132{sup 0}C) and the measured gradient was 0.77 psi/ft. The gross sand thickness was 270 feet, the net sand thickness 190 feet, and the tested interval 58 net feet. The temperatures and pressures encountered approached the limits of the surface-recording bottomhole pressure gauge and particularly the single-conductor cables on which the gauges were run. The objectives of the tests were all accomplished, and data were obtained which will contribute to the overall assessment of the geopressured-geothermal resource of the Upper Gulf of Mexico basin. In general, the gas solubility (22.8 scf/bbl) was as expected for the temperature, pressure, and salinity of the brine. The produced water was more saline than expected (160,000 mg/l). The high concentrations of dissolved solids, coupled with the evolution of CO{sub 2} from these waters during production, created a scaling problem in the tubular goods and surface equipment that will have to be addressed in future tests; DOE/ET/28460-1 Title: Investigation and evaluation of geopressured-geothermal wells.
