Resource assessment for geothermal direct use applications
This report discusses the topic geothermal resource assessment and its importance to laymen and investors for finding geothermal resources for direct-use applications. These are applications where the heat from lower-temperature geothermal fluids, 120 to 200/sup 0/F, are used directly rather than for generating electricity. The temperatures required for various applications are listed and the various types of geothermal resources are described. Sources of existing resource data are indicated, and the types and suitability of tests to develop more data are described. Potential development problems are indicated and guidance is given on how to decrease technical and financial risk and how to use technical consultants effectively. The objectives of this report are to provide: (1) an introduction low-temperature geothermal resource assessment; (2) experience from a series of recent direct-use projects; and (3) references to additional information.

Porosity of coastal deltaic sandstones, Cerro Prieto geothermal field, Baja California, Mexico
Core porosity values for sandstones and density log-derived porosities for sandstone-siltstone-shale sequences indicate a range from less than 1% to 40% at the Cerro Prieto geothermal field, Baja California, Mexico. Mean porosity values indicate that a general trend of decreasing porosities with increasing depth from 35% at 600 m to 10% at 2300 m is complicated by the 15 to 30% porosities in the 350/sup 0/C hot water zone at about 2700 m depth. Scanning electron microscopy documents secondary dissolution porosity, mineral overgrowths, and abundant clay minerals. Core permeability ranges from 0.1 to 1000 millidarcies for the more than 50 cores studied. The porosity variability indicates that geothermal systems provide an ideal setting for testing concepts of dissolution porosity and increased secondary dissolution permeability that could be useful for nuclear waste storage as well as petroleum reservoir engineering.

New Mexico State University Campus geothermal demonstration project
This report presents the design, construction highlights, and performance of the New Mexico State University Campus Geothermal Demonstration Project at Las Cruces, New Mexico. Construction started in July 1981, first system use was January 1982, and the system was dedicated on April 21, 1982. Included herein are summary observations after two years of use. The geothermal hot water from New Mexico State University wells is used to heat potable water, which in turn provides 83 percent of the domestic hot water on the New Mexico State University campus, as well as space heat to two buildings, and for two heated swimming pools. The original system is providing service to 30 total buildings, with two additional buildings (150,000 square feet) in process of geothermal conversion.) The system overall performance has been excellent, except for geothermal well pump problems. In terms of operating efficiency, the system has exceeded the design parameters. In spite of abnormally high costs for well and pump repairs, the system has shown a positive cost avoidance of more than $118,000 for the first year of operation. For the first two full years of operation, the system has produced a net positive cost avoidance of more than $200,000. Payback …
