Geothermal Development in El Salvador1
Studies of the geologic characteristics and underground fluids utilization in the Ahuachapán field have permitted an adequate exploitation of the geothermal system. Equilibrium between recharge and mass withdrawal has been established by a geothermal production and reinjection program.
The first geothermal power unit at Ahuachapán, with a capacity of 30 MW, was commissioned in May 1975; a second unit of the same size started operations 1 year later. The construction of the third unit of 35 MW is presently in progress and will bring the total installed capacity to 95 MW in January 1980.
New geothermal areas in the eastern part of the country are under exploration. Geologic, geophysical, and geochemical surveys are under way and temperatures up to 286°C were measured in the first deep well drilled.
Figures & Tables
The energy and mineral resources of the vast Pacific basin and its neighboring land areas play a vital role in meeting the ever-growing needs of society worldwide. Building on the foundation of a highly successful conference held in 1978, this volume contains 51 of the 135 papers presented there. Subjects included are general and specific in nature--oil, gas, and coal resources; geothermal fields, uranium; tin; evaporites, trace elements; water resources; magma energy and fuels from magma. Geological and geophysical techniques, and also the new tool of remote sending for petroleum and minerals exploration are represented. Tectonics, structure fundamentals, subsurface hazards, international treaties and the law of the deep sea are discussed. Seventeen countries and regions are represented in these papers: Thailand, Nicaragua, the United States, Japan, Peru, Antarctica, El Salvador, Australia, Mexico, Taiwan, New Zealand, China, Chile, Indonesia, Canada, and the Pacific Ocean.
