Groundwater quality and geothermal energy. The case of Cerro Prieto Geothermal Field, México

Renewable Energy, 2014
Abstract The influence of the Cerro Prieto Geothermal Field (CPGF) on groundwater quality of the close-by agricultural area was evaluated by means of chemical and isotopic determinations. According to irrigation standards, concentrations of As, Cd, Pb, Crtot, Cr(VI), Cu, Cd, Hg, B in agricultural wells showed the suitability of the water for ...

Well interference tests at the Cerro Prieto geothermal field

Geothermics, 1980
Abstract Two well interference tests were carried out by the LBL at the Cerro Prieto geothermal field located in Baja California, Mexico, during 1978. The first test incorporated five wells located about 1 km south of the power plant. Well M-101 was monitored as an observation well while four wells, M-91, M-51, M-90 and M-50 were developed.

Seismicity studies in the region of the Cerro Prieto geothermal field

Geothermics, 1980
Abstract We report results from seismicity studies in the region of the Cerro Prieto geothermal field. These studies were conducted with local short period seismic arrays during 1974–1975 and 1977–1978. During the latter period, horizontal seismometers were used for better control on the S-wave arrival times.

Self-potential studies at the cerro prieto geothermal field

Geothermics, 1980
A reconnaissance self-potential survey conducted at the Cerro Prieto geothermal field revealed a dipolar anomaly of about 160 mV maximum peak-to-peak amplitude and covering an area of more than 400 km2. The anomaly is centered close to the present production zone, and its axis runs nearly due north-south, passing roughly through the location of the ...

Geochemical evidence of drawdown in the Cerro Prieto geothermal field

Geothermics, 1979
Abstract Some wells of the Cerro Prieto geothermal field have undergone changes in the chemistry of fluids produced which reflect reservoir processes. Pressure decreases due to production in the southeastern part of the field have produced both drawdown of lower chloride fluids from an overlying aquifer and boiling in the aquifer with excess steam ...

Preliminary geochemical model of the Cerro Prieto geothermal field

Geothermics, 1979
Abstract The distribution of the Na-K-Ca index values in the geothermal aquifer of Cerro Prieto indicates a probable cold-water recharge in the northern and western parts of the present producing field. In the central part of the field, the distribution of Na-K-Ca values is very irregular, due to the effect of percolation or the vertical descending ...

Preliminary studies of brine reinjection at the Cerro Prieto geothermal field

Geothermics, 1980
Abstract At the present time, Units 1 and 2 of the Cerro Prieto power plant generate 75 MW of power. For this purpose, about 2200 t/h of fluids are produced. Of this, 700 t/h of steam are sent to the plant and 1500 t/h of spent brine are discarded into an evaporation pond.

Brine treatment test for reinjection on cerro prieto geothermal field

Geothermics, 1989
Abstract Reinjection of disposal brine from the Cerro Prieto Geothermal Power Plant System is attractive mainly because, on top of solving the brine disposal problem, it may significantly contribute to extend the reservoir useful lifetime, through thermal and hydraulic recharge. Because the high concentration of colloidal silica in the disposal brine,

Gas chemistry and thermometry of the Cerro Prieto, Mexico, geothermal field

Geothermics, 1984
Gas compositions of Cerro Prieto wells in 1977 reflected strong boiling in the reservoir around wells M-20 and M-25. This boiling zone appeared to be collapsing in 1982 when a number of wells in this area of the field were shut-in. In 1977 and 1982, gas compositions also showed boiling zones corresponding to faults H and L postulated by Halfman et al. (

Preliminary isotopic studies of fluids from the Cerro Prieto geothermal field

Geothermics, 1979
Abstract Preliminary isotopic studies of Cerro Prieto geothermal fluids and earlier studies of Mexicali Valley ground waters suggest local recharge of the geothermal system from the area immediately to the west. Oxygen isotope exchange of water with reservoir rock minerals at temperatures increasing with depth has produced fluids with oxygen-18 ...
