Preliminary assessment of the geothermal resource potential of the Yuma area, Arizona

Geohydrology and water resources of the Papago Farms-Great Plain area, Papago Indian Reservation, Arizona, and the upper Rio Sonoyta area, Sonora, Mexico

“…As along the Mesquite Mountains fault, the vertical offset of the Molenitus fault is also abrupt and may be as much as 6,000 ft. The existence of the Mesquite Mountains and Molenitus faults is further reinforced by a geothermal investigation by Stone (1980). Stone (1980) concluded that a low-temperature geothermal anomaly that is centered in the north-central area of Papago Farms may be caused by warm ground-water that moves up the intersecting fault zones.…”

“…Regional geophysical maps that include the Papago FarmsGreat Plain area are in Hargan (1978), U.S. Geological Survey (1980), International Exploration, Inc. (written commun., 1979, Oppenheimer andSumner( 1981), andLysonski andothers (1981). Geothermal potential at Papago Farms was evaluated by Stone (1980). Basic quality-of-water and waterlevel data for the Papago Farms-Great Plain area are published in Heindl and Cosner (1961), Heindl and others (1962), Hollett (1981b), and Hollett and Garrett (1983).…”

“…At Papago Farms (area G3, sheet 3), five irrigation wells that are 128 to 290 m deep contain 38°C to 51°C water that has a sodium bicarbonate composition. A mininura reservoir temperature of 80°C is predicted and geothermal resources of about 140°C may be present at depths greater than 2,000 m (Witcher and others, 1982;Stone, 1980). Six warm-water wells near Glla Bend (east part of area Gl, sheet 3) have temperatures ranging from 35°C to 49°C and are designated as having geothermal potential (Witcher and others, 1982).…”
