GeothermEx, Inc. has been contracted by the Department of Business, Economic Development and Tourism (DBEDT) to provide consulting services relating to the development of geothermal resources in the State of Hawaii. Assessment of the Kilauea East Rift Zone (KERZ) of the Island of Hawaii (figure 2.1), including the commercial geothermal development in the Puna area, has been the focus of the effort. The first assessment report was submitted to DBEDT in September 1992. It was anticipated that a second annual report would be issued at the end of 1993, which would include the results of the latest drilling efforts, an analysis of production and injection data, and forecasts of future reservoir behavior from a numerical simulation study. However, due to long delays in completing the wells required for the 25 MW Puna Geothermal Venture (PGV) power plant and major changes in the behavior of production well KS-10, the second report was postponed for one year. Since the September 1992 report was written, GeothermEx has collected a significant amount of new data on drilling, testing, logging, production, injection, fluid chemistry and power plant operation, all of which are reported onherein.This report is similar in structure to the September 1992 report, with some additions. The major topics discussed herein are a discussion and analysis of the available database, an evaluation of the results of geological, geophysical and geochemical surveys, principally in the KERZ, the results of all drilling and well testing in the KERZ to date, a review of the production and injection history of the Puna Geothermal Venture (PGV) project and power plant, a conceptual hydrogeologic model of the KERZ geothermal system, an evaluation of the extent, characteristics and geothermal energy reserves within the KERZ, a discussion of the methodology and a presentation of results from numerical modeling of the Puna geothermal reservoir, a summary of the Statewide geothermal resource assessment program, including an independent assessment of the likelihood of finding high-temperature geothermal reservoirs throughout the Hawaiian Islands, and recommendations for continued work.
