It is the function of GPM to identify trends in the use of this resource and to provide a historical record of its development pathway. The information assembled for this issue of GPM indicates that trends in the use of geothermal energy in this country and abroad continue to be very positive. Favorable sentiments as well as pertinent actions on the part of both government and industry are documented in almost every section. The FEDERAL BEAT points up that the National Energy Strategy (NES) developed at the highest levels of the US government recognizes the environmental and energy security advantages of renewable energy, including geothermal, and makes a commitment to substantial diversification'' of US sources of energy. With the announcement of the construction of several new plants and plant expansions, the INDUSTRY SCENE illustrates industry's continued expectation that the use of geothermal energy will prove profitable to investors. In DEVELOPMENT STATUS, spokesmen for both an investor-owned utility and a major geothermal developer express strong support for geothermal power, particularly emphasizing its environmental advantages. DEVELOPMENT STATUS also reports that early successes have been achieved by joint DOE/industry R D at The Geysers which will have important impacts on the future management of this mature field. Also there is increasing interest in hot dry rock.

  	Citation × Citation Citation Abstract Copy Title: Hot Dry Rock Geothermal Energy Development Program. Annual Report, Fiscal Year 1983 Author: Smith, M.C. (comp.) Year: 1985 Emphasis was on hydraulic-fracturing experiments at depths around 3.5 km (11,473 ft) in the two inclined wells of the Phase II system at Fenton Hill, New Mexico; on improved facilities and techniques for mapping the source locations of acoustic signals generated by the fracturing events; on mathematical modeling of the fracture systems produced in these and earlier experiments; and on development of a family of slimline high-temperature downhole instruments that can be used within or through relatively small-diameter pressure tubing. Hydraulic fracturing at a vertical depth of approximately 3500 m (11,500 ft) in well EE-2, the deeper well, produced fractures that, in acoustic maps, appear to occupy a large, roughly ellipsoidal volume whose major axis is directed to the north of the other well, EE-3. Hydraulic fracturing from EE-3 at a similar depth produced another set of fractures that appear to be approximately parallel to and centered about 180 m (600 ft) east of the earlier set. Subsequent fluid injections reduced the distance between the two sets, but no hydraulic connection between them was established. Modeling the silica concentrations of fluid circulated through the earlier Phase I system indicates that this type of permeation also contributes significantly to heat extraction during system operation. The precision and accuracy of locating the sources of acoustic signals detected during hydraulic-fracturing operations have been increased by improvements in equipment, drilling of another deep hole for geophone emplacement, and additional station calibrations. Analysis of the signals has also been improved and broadened. Development of slimline downhole instruments has included a detonator tool, a geophone package, and final design of a high-temperature borehole acoustic televiewer. A crosswell acoustic transceiver has also been developed for investigating rock type and structure between wellbores. 32 refs., 35 figs. Title: Hot Dry Rock Geothermal Energy Development Program.

  	Citation × Citation Citation Abstract Copy Title: Geothermal Progress Monitor: Report No. 18, December 1996 Author: Assistant Secretary for Energy and Efficiency and Renewable Energy, Geothermal Division Year: 1996 The near-term challenges of the US geothermal industry and its long-range potential are dominant themes in this issue of the US Department of Energy (DOE) Geothermal Progress Monitor which summarizes calendar-year 1996 events in geothermal development. Competition is seen as an antidote to current problems and a cornerstone of the future. Thus, industry's cost-cutting strategies needed to increase the competitiveness of geothermal energy in world markets are examined. For example, a major challenge facing the US industry today is that the sales contracts of independent producers have reached, or soon will, the critical stage when the prices utilities must pay them drop precipitously, aptly called the cliff. However, Thomas R. Mason, President and CEO of CalEnergy told the DOE 1996 Geothermal Program Review XIV audience that while some of his company's plants have ''gone over the cliff, the world is not coming to an end.'' With the imposition of severe cost-cutting strategies, he said, ''these plants remain profitable... although they have to be run with fewer people and less availability.'' The Technology Development section of the newsletter discusses enhancements to TOUGH2, the general purpose fluid and heat flow simulator and the analysis of drill cores from The Geysers, but the emphasis is on advanced drilling technologies Title: Geothermal Progress Monitor: Report No. 18, December 1996 Author: Assistant Secretary for Energy and Efficiency and Renewable Energy, Geothermal Division Year: 1996 The near-term challenges of the US geothermal industry and its long-range potential are dominant themes in this issue of the US Department of Energy (DOE) Geothermal Progress Monitor which summarizes calendar-year 1996 events in geothermal development.
