Two interference well tests, conducted at the U.S. Bureau of Reclamation's East Mesa geothermal test facility in Southern California by the Lawrence Berkeley Laboratory, serve to better define the geothermal reservoir's geometry and hydrologic characteristics. Temperature profiles taken indicate that the reservoir is approximately 3000 feet thick and is located about 6000 feet below the ground surface. The temperature at depth is approximately 350{sup 0}C. The two well tests, each of approximately 10 days' duration yield respectively reservoir transmissivities of 11,200 and 29,500 millidarcy-feet and compressibilities of 5.7 x 10{sup -3} and 2.1 x 10{sup -3} feet per psi. The tests also indicate the possible presences of a sealed fault and a leaky fault in the reservoir.
