The purpose of this field trip was to investigate the extent, thickness versus distance relationships, and source of a young scoriaceous air-fall deposit exposed in the vicinity of the Kamodjang geothermal field. This deposit was first noticed in October 1981, exposed along the highway through the Kamodjang area. The eruption of similar scoria in the future could endanger the village of Pangkal…
The following is a proposed scientific programme for the rapid scientific assessment of the Dieng geothermal field in Central Java, Indonesia. The programme of work is designed so that exploration drilling, once the results of the assessment show the field has the potential to warrant drilling, could commence in early December. Consequently, the proposed programme incorporates a high work input…
Additional Well Characteristics Test for DNG-8, DNG-13 and DNG-14 was planned to check the characteristics of the Sikidang geothermal area, and was completed at the end of June 1990 successfully with kind cooperation of PLN and PERTAMINA.
The planning and development which led to to the Technical Program presented by Volume 24 of the GRC Transactions was carried out by the Technical Program Committee for the GRC 2000 Annual Meeting. The papers presented in this volume were reviewed by members of the committee and experts from the professional geothermal development community.
Los Alamos National Laboratory, with support from the U.S. Department of Energy, has been developing geothermal energy technology for nearly 20 years. The technology and experimental verification concepts developed by the Laboratory’s Hot Dry Rock Program have demonstrated tremendous potential for what is now known as heat mining- the creation of a man-made heat-exchange system in hot, fractu…
The rapid growth of geothermal electrical generation in recent years has been accompanied by rapid growth in our knowledge of the behavior of reservoirs in their natural and exploited states. Good textbooks and literature surveys exist both for the earth sciences and for surface plant engineering.
With the threat of depletion of conventional sources of energy there has been increased interest in harnessing geothermal energy for man’s use in many countries. However, there as comparatively few people with wide experience in the science and technology of developing this new energy resources.
The current energy crisis has generated an increased interest in alternate source of energy. Resources such as geothermal, solar, and ocean thermal are being actively considered for wide-spread development in the United States and many other countries throughout the world.
Geothermics can be defined as the study of the temperature distribution in the earth and the phenomena which influence that distribution. At the earth’s surface and in the atmosphere, complex meteorological events occur which are strongly influenced by temperature. These phenomena will only be mentioned briefly.
The outflow of heat from the Earth’s interior, the terrestrial heat flow, and the temperature field at depth are determined by deep-seated tectonic processes. The knowledge of the regional heat flow patterns is thus very important in geophysics and provides a useful tool for studying crustal and lithospheric structures and for understanding the nature of their evolution.
