Inspection of the Heber binary-cycle geothermal project

Description: We concluded that DOE had effective management control procedures to monitor project costs and the design, construction and demonstration activities. Lessons learned from previous DOE geothermal projects were applied and technical information generated from the Heber plant will be transferred to the public and private sectors by the project participants. We also identified the following issues that concerned us: Revenue Sharing: under existing revenue sharing provisions in the Cooperative Agree… more

Assessment of the injectability of conditioned brine produced by a reaction clarification: gravity filtration system in operation at the Salton Sea geothermal field, Southern California

Description: A Demonstration Reaction Clarifier - Gravity Filtration System with a 1600 GPM throughput capability was in operation at the joint DOE-SDG and E-MAGMA test facility located in the Salton Sea Geothermal Field, southern California, during the summer of 1979. The system, which was designed to condition spent effluent from a 10 MWe-size geothermal power plant, removes supersaturated dissolved species and residual suspended solids from brine prior to subsurface brine disposal via injection wells.

Workshop on environmental control technology for The Geysers-Calistoga KGRA

Description: The proceedings of six work groups that discussed techniques to prevent and abate noise, hydrogen sulfide emissions, and accidental spills of chemicals and geothermal wastes at The Geysers-Calistoga KGRA are reported. Problems associated with well completion and production, and with systems, components, and materials, and their effects on emissions were also discussed. The comments and recommendations of the work groups are included in the proceedings. (MHR)

East Mesa geothermal pump test facility (EMPTF). Final report

Description: The design, fabrication and installation of a geothermal pump test facility (EMPFT) at the DOE geothermal site at East Mesa, California which is capable of testing 70 to 750 horsepower downwell pumps in a controlled geothermal environment were completed. The facility consists of a skid-mounted brine control module, a 160 foot below test well section, a hydraulic turbine for power recovery, a gantry-mounted hoist for pump handling and a 3-phase, 480 VAC, 1200 amp power supply to handle pump elec… more

East Mesa geothermal pump test facility (EMPTF). Final report

Description: Barber-Nichols has completed the design, fabrication and installation of a geothermal pump test facility at the DOE geothermal site at East Mesa, California which is capable of testing 70 to 750 horsepower downwell pumps in a controlled geothermal environment. The facility consists of a skid-mounted brine control module, a 160 foot below ground test well section, a hydraulic turbine for power recovery, a gantry-mounted hoist for pump handling and a 3-phase, 480 VAC, 1200 amp power supply to han… more

Use of geochemical-equilibrium computer calculations to estimate precipitation from geothermal brines

Description: The Helgeson-Herrick geochemical code was used to calculate the solubility of NaCl, KCl, and KCl-NaCl in water and to predict which minerals will precipitate from Salton Sea Geothermal Field brines. The code's predictions of sulfide-silicate precipitation from the Magmamax No. 1 brine are in good agreement with field tests of scaling, although the observed sulfide-silicate scale matrix is in amorphous form, rather than the crystalline form predicted by the code. The code's predictions of scale … more

Bulalo field, Philippines: Reservoir modeling for prediction of limits to sustainable generation

Description: The Bulalo geothermal field, located in Laguna province, Philippines, supplies 12% of the electricity on the island of Luzon. The first 110 MWe power plant was on line May 1979; current 330 MWe (gross) installed capacity was reached in 1984. Since then, the field has operated at an average plant factor of 76%. The National Power Corporation plans to add 40 MWe base load and 40 MWe standby in 1995. A numerical simulation model for the Bulalo field has been created that matches historic pressure … more

Eighteenth workshop on geothermal reservoir engineering: Proceedings

Description: PREFACE The Eighteenth Workshop on Geothermal Reservoir Engineering was held at Stanford University on January 26-28, 1993. There were one hundred and seventeen registered participants which was greater than the attendance last year. Participants were from eight foreign countries: Italy, Japan, United Kingdom, Mexico, New Zealand, the Philippines, Guatemala, and Iceland. Performance of many geothermal fields outside the United States was described in several of the papers. Dean Gary Ernst opene… more

Behavior of Rare Earth Element In Geothermal Systems; A New Exploration/Exploitation Tool

Description: The goal of this four-year project was to provide a database by which to judge the utility of the rare earth elements (REE) in the exploration for and exploitation of geothermal fields in the United States. Geothermal fluids from hot springs and wells have been sampled from a number of locations, including: (1) the North Island of New Zealand (1 set of samples); (2) the Cascades of Oregon; (3) the Harney, Alvord Desert and Owyhee geothermal areas of Oregon; (4) the Dixie Valley and Beowawe fiel… more
