During 1964-65 Earth Energy Inc. drilled R. Brady EE no. 1 to a depth of 5062 feet. This well has a bottom-hole temperature of 414°F (fig. 4) but is not a producer, and it is not known if this is an equilibrium profile. This is the hottest well in the Brady's area, and an injection test has been performed on this well (Rudisill and Dykstra, 1978).

. In 1975 Brady no. 8 was drilled to a depth of 3469 feet, and it supplies geothermal fluids to Geothermal Food Processors' food dehydration plant. A limited production test has been performed on Brady no. 8 in conjunction with the food dehydration plant (Rudisill, 1978). Three other shallow wells have been drilled by Magma Power Company. These are Brady no. 9 and two shallow injection wells. There is no information available concerning these wells.

All of these wells are located along a narrow zone 1500 feet in length (fig. 3). Only two wells have been drilled outside this zone. The first, SP Brady no. 1, was drilled in 1974 to a depth of 7275 feet. This well had a low flow rate and a bottom-hole temperature of 371° (fig. 4). The second well, SP Brady no. 2, was drilled in
