Preliminary Report on Reservoir Tests at East Mesa Geothermal Site, California

摘要

Reservoir tests on the geothermal well field at East Mesa, California were conducted in two phases. The first phase was aimed at conducting a production test on well 31-1. This production test was to consist of placing the pressure gage (HP gage) at a depth of 5700 feet within 31-1, produce 31-1 at the rate of approximately 50 gpm for about 48 hours, and observe the consequent pressure changes. This production test could not be carried out successfully because the HP gage failed to function satisfactorily at a temperature of 318 exp 0 F (159 exp 0 C) prevalent at 5700 feet. During the second phase of the testing operations, an interference test was conducted with the help of two HP gages. The interference test consisted in producing 6-2 and observing the pressure changes in wells 6-1 and 8-1. The details of this test are reported. (ERA citation 03:023537)
