  • Thomas, Donald M.; Sakai, Hitoshi (Fourth International Symposium on Water-Rock Interaction, 1983-08)
    "The HGPA well, located on the Lower East Rift Zone of Kilauea Volcano, was drilled in 1976. It is completed to a depth of 1966 m 1768 m below sea level and has a bottom hole temperature of approximately 360C. The well is ...
  • Cox, Malcolm E.; Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1979)
    Because of the complex geological and hydrological conditions and the virtual lack of thermal springs, regional geothermal investigations in Hawaii require the use of techniques substantially different from those conventionally ...
  • Cox, Malcolm E.; Thomas, Donald M. (Geothermal Resources Council, 1979)
    During the regional assessment for potential geothermal areas in Hawaii, several quantitative and qualitative chemical geothermometers were applied to groundwaters with little apparent success. The problems most commonly ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1990-01)
    "The purpose of this report on the geothermal well HGP-A, located in the Kapoho, Puna, Hawaii, is to review the construction and integrity of the well. Pertinent information from the HGP-A well record, daily field reports, ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics and Planetology, 1994-03-18)
    The geochemical monitoring program has undertaken two related responsibilities: 1) Conduct a detailed analysis of the chemistry and dynamics of the shallow groundwater system on the Lower East Rift (LERZ); and 2) Evaluate ...
  • Thomas, Donald M. (University of Auckland Geothermal Institute, 1982)
    The Hawaii Geothermal Project Well-A, located on the Island of Hawaii, was completed in 1976 to a depth of 1966 meters. The bottomhole temperature, under shut-in conditions, is 360°C and at full discharge is capable of ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics, 1987-10)
    The HGP-A geothermal well, located on the lower east rift system of Kilauea volcano, has provided steam and hot water to a 3MWe wellhead generator facility on a continuous basis since December 1981. Since production began ...
  • Thomas, Donald M. ([n.p.], 1983-05)
    "During the last several months a number of concerns have been expressed regarding adverse environmental and health impacts of anticipated geothermal development in Hawaii. Some of the concerns expressed have merit and ...
  • Thomas, Donald M. (Geothermal Resources Council, 1979-09)
    The preliminary phase of a geothermal resource assessment program for the State of Hawaii has been completed. Several locations on all the major islands of the Hawaiian chain have been identified as potentially having a ...
  • Thomas, Donald M. (Pergamon Journals Ltd., 1986)
    Report on statewide geothermal resources assessment conducted under the DOE Western States Cooperative program.
  • Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1985)
    This document summarizes the available geologic, geochemical, and geophysical data for all prospective geothermal resource areas on all islands in Hawaii current to 1985.
  • Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, [unknown])
    Sections: Geology Program and Budget
  • Kajiwara, Leslie M.; Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1982)
    A summary of regulatory processes associated with development of geothermal resources in 1982.
  • Boyd, Tonya L.; Thomas, Donald M.; Gill, Andrea T. (Geo-Heat Center, Oregon Institute of Technology, 2002-09)
    "The Hawaiian Islands lie above a geological “hot spot” in the earth’s mantle that has been volcanically active for the past 70 million years, with the island of Hawaii (the “Big Island”) having the most recent activity. ...
  • Thomas, Donald M.; Cox, Malcolm E.; Kauahikaua, James P.; Mattice, Mark D. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1980-02)
    During 1979 reconnaissance field surveys were conducted on the islands of Hawaii, Maui, and Oahu with the objective of confirming groundwater chemical data and geophysical data compiled during the preliminary regional ...
  • Thomas, Donald M.; Cox, Malcolm E.; Lienert, Barry R.; Kauahikaua, James P.; Mattice, Mark D. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1980)
    During 1979 reconnaissance field surveys were conducted on the islands of Hawaii, Maui, and Oahu with the objective of confirming groundwater chemical data and geophysical data compiled during the preliminary regional ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics, 1990-08)
    The Hawaii Geothermal Project, since its initiation in 1972, has not only demonstrated that there is a viable geothermal resource present on the Kilauea East Rift Zone, it has also produced a wealth of information about ...
  • Thomas, Donald M. (Geological Society of America, 32509)
    Introduction: "One consequence of the volcanism that formed the islands of the Hawaiian archipelago is the evolution of hydrothermal activity. Surface manifestations of active hydrothermal systems are evident on the young, ...
  • Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa / HGP Wellhead Generator Project, 1980-05)
    "The primary objectives of the chemistry group efforts during the two-week test of the HGP-A well were as follows: 1) determine the quantities and concentrations of the major chemical constituents in the geothermal fluids ...
  • Cox, Malcolm E.; Sinton, John M.; Thomas, Donald M.; Mattice, Mark D.; Kauahikaua, James P.; Helstern, Donald M.; Fan, Pow-Foong (U.S. Geological Survey, 1979-09)
    "Studies of Lualualei Valley, Oahu have been conducted to determine whether a thermal anomaly exists in the area and, if so, to identify sites at which subsurface techniques should be utilized to characterize the resource. ...
