Chloride/Magnesium Ratio of Shallow Groundwaters as a Regional Geothermal Indicator in Hawaii

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 ...
Cl/Mg Ratio of Hawaiian Groundwaters as a Regional Geothermal Indicator

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 ...
A Geochemical Case History of the HGP-A Well, 1976-1982

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 ...
Geothermal Resource Assessment for Hawaii

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 ...
Geothermal Resources Assessment in Hawaii: Article

Thomas, Donald M. (Pergamon Journals Ltd., 1986)

Report on statewide geothermal resources assessment conducted under the DOE Western States Cooperative program.
Geothermal Resources Assessment in Hawaii: Final Report

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.
Handbook of Federal, State and County Permits Relevant to Geothermal Development in Hawaii

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.
Hawaii Geothermal Resource Assessment Program, Direct Heat Resource Assessment Interim Report, February 1, 1979 to January 31, 1980

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 ...
Non-Condensable Gas Reinjection Test Conducted at the HGP-A Wellhead Generator Facility (September 1, 1989 through December 10, 1990), Final Report

Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1990)

Discussion of a pilot test of recombining steam, geothermal brine, and non-condensible gases as a method of disposing of geothermal waste fluids.
An Overview of Some Geologic and Environmental Aspects of Geothermal Development in Hawaii

Thomas, Donald M. (Hawaii Institute of Geophysics, University of Hawaii at Manoa, 1982)

A generalized discussion of the geothermal resources in Hawaii and their geologic and environmental characteristics.
Silica Recovery and Control in Hawaiian Geothermal Fluids, Final Report

Thomas, Donald M. (University of Hawaii, 1992)

A series of experiments was performed to investigate methods of controlling silica in waste geothermal brines produced at the HGP-A Generator Facility. Laboratory testing has shown that the rate of polymerization of silica ...
A Simple, Inexpensive Downhole Geothermal Fluid Sampler

Thomas, Donald M. (Geothermal Resources Council, 1979)

Several commercially available downhole water samplers have been used in a high temperature geothermal well in Hawaii; none have been able to withstand the temperature-pressure conditions found at the bottom of the hole ...
