Book excerpt: In 1972, the first well flow tests were conducted by NARCO and Magma Power to determine reservoir characteristics such as mass flow, temperature, stability, and mineral content of geothermal brine from the exploration wells. The results of these tests were encouraging. Brine temperatures were relatively hot, and salinity was less than previously experienced. Results were sufficient to justify further testing of the process design to determine an appropriate energy conversion cycle for a power plant. Both the flash cycle and binary cycle were considered. In the binary cycle, geothermal heat is transferred from hot brine to a secondary working fluid by means of heat exchangers. The heated secondary fluid expands to drive a turbine-generator. The flash cycle was rejected because the high measured noncondensible gas content of the brines seriously reduced the cycle efficiency. The reduced salinity was expected to result in reduced scaling characteristics. For these reasons the binary cycle was selected for initial design and field testing. In 1973, a series of field tests was conducted to support the design of the binary conversion cycle. Unfortunately, a rapid decline in heat exchanger performance resulting from scaling demonstrated a need to reevaluate the cycle design. A flash/binary process was chosen as the basis for facility design modifications and additional field testing. Design modifications were to use as much of the original design as possible in order to minimize cost. In March of 1974, SDG & E resumed field testing at Niland using reduced size models of the new flash/binary design. The 1974 test program confirmed the decision to modify the design, construction, and operation of the GLEF in a four-stage, flash/binary cycle configuration. In May of 1975, the design was completed and construction of the GLEF began. Startup operations were initiated and in June 1976 the facility was dedicated. In the fall of 1976 while debugging and initial operation was being accomplished, a test program was developed to provide additional basic information necessary for the design of a commercial flash/binary geothermal plant. The primary objective of the program was to develop binary heat exchanger heat design data under a variety of conditions.

Available in PDF, EPUB and Kindle. Book excerpt: San Diego Gas and Electric Company (SDG and E) has been associated with geothermal exploration and development in the Imperial Valley since 1971. SDG and E currently has interests in the four geothermal reservoirs shown. Major SDG and E activities have included drilling and flow testing geothermal exploration wells, feasibility and process flow studies, small-scale field testing of power processes and equipment, and pilot plant scale test facility design, construction and operation. Supporting activities have included geothermal leasing, acquisition of land and water rights, pursual of a major new transmission line to carry Imperial Valley geothermal and other sources of power to San Diego, and support of Magma Electric's 10 MW East Mesa Geothermal Power Plant.

Available in PDF, EPUB and Kindle. Book excerpt: What are the effects on an isolated region when an entirely new and major energy resource is developed to commercial proportions? What happens to the population, the economy, the environment, the community, and societal relations? How does the government frame work respond, the family structure adapt, the economy expand, and life styles change under the impact of new forces which hold a prom ise of much benefit and a risk of adverse consequences? Imperial County, California, has a population of less than 90,000 people. This population has been exceptionally stable for years, cen tered as it is in an agricultural and recreational framework. The county is somewhat cut off from other areas by geographic barriers of moun'" tains and desert, by state and natural boundaries, and is the most remote of all 58 counties of California from the state capitol, Sacra mento. In the decade of the 1950s, geographical explorations for oil re vealed some anomalous structures underlying the desert and agricul tural areas in Imperial County. These, when drilled, seemed to be oil less and hot, and so lacked attractiveness to petroleum wildcatters. In the decade of the 1960s, Dr.
