Book excerpt: The formulation and evolution of the Federal Hot Dry Rock Geothermal Energy Development Program at the Los Alamos Scientific Laboratory are traced. Program motivation is derived from the enormous potential of the resource. Accomplishments to date, including the establishment and evaluation of the 5-MW/sub t/ Phase 1 reservoir at Fenton Hill, NM and various instrument and equipment developments, are discussed. Future plans presented include (1) establishment of a 20- to 50-MW/sub t/ Phase 2 reservoir at Fenton Hill that will be used to demonstrate longevity and, eventually, electric power production and (2) the selection of a second site at which a direct thermal application will be demonstrated.

Book excerpt: With completion of the repairs of EE-2 wellbore in FY88, the major effort in FY89 will be directed toward the remaining preparations for the Long-Term Flow Test (LTFT) now scheduled to begin in September 1990. Procurement of components and equipment and installation of the surface system will continue through this and the next fiscal year to be ready for the LTFT in September 1990. Reservoir experiments will consist of pressurization and flow tests to establish further characteristics of the Phase II reservoir, particularly operating water losses. Laboratory studies will continue work on fracture healing and complete adsorption tests for chemically-reactive tracer work. Cleaning and relining of the EE-I pond to meet New Mexico State requirements, started in FY88, will be completed. Reanalysis of seismic data and automation of seismic data techniques will continue. Monitoring for environmental information, routine operations, security, health and safety training, and reporting activities will continue. The program's objectives are: (1) To develop HDR drilling, hardware and instrumentation technology for energy extraction and conduct a successful energy extraction field experiment of the Phase II reservoir. (2) To verify that the environmental consequences of HDR development are acceptable. (3) To improve HDR technology to the point where electricity could be produced commercially from a substantial number of known hot dry rock resource sites in a cost range of 5 to 8 cents/kWh. (4) To evaluate the performance of the Fenton Hill Phase II reservoir by 1992. That performance consists of system operating characteristics, including thermal drawdown, energy output, reservoir impedance, and water consumption.

Book excerpt: Recent accomplishments of the program are highlighted by a successful limited term flow test of the Phase 2 reservoir at the Fenton Hill site near Los Alamos. This reservoir connection was established by sidetracking one of the deep wells into hydraulically fractured areas, identified by microseismic data after original fracture attempts failed to connect the two wells. Hydraulic communication was improved by supplemental fracturing. Preliminary testing indicated a reservoir with fracture volume and heat production area surpassing the values from the earlier Phase 1 reservoir. Following completion of the downhole reservoir system, preparations were made for a reservoir-energy-extraction test. This Initial Closed Loop Flow Test (ICFT) was needed to obtain operating characteristics for planning a much longer test for thorough reservoir evaluation. The 30-day ICFT succeeded with final production of about 10 MWt at 192°C, while injecting 285 gpm at 4600 psi and producing 206 gpm at 500 psi. The water loss rate and flow impedance were high, 27% and 18 psi/gpm respectively, but were declining. Radioactive tracer tests indicated reservoir volume growth during the experiment which was continuously monitored for acoustic or microseismic activity. Following the flow test, experiments were continued for several months during the venting process. Preparations are now underway for the Long Term Flow Test (LTFT). To understand as much as possible about the Phase 2 reservoir and to demonstrate the commercial feasibility of energy from HDR reservoirs, a flow test of approximately one year's duration is deemed necessary. Part of the preparation for the LTFT is the workover and repair of the production well and the installation of a competent overall flow loop and energy exchange system. 7 refs., 5 figs.

This book was released on 2012-04-23 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining the Earth's Heat: Hot Dry Rock Geothermal Energy describes the work carried out by the Los Alamos National Laboratory to turn an idealistic concept - that of drawing useful amounts of energy from the vast underground store of hot rock at reachable depths - into a practical reality. This book provides comprehensive documentation of the over two decades of experiments carried out at the test site at Fenton Hill, New Mexico, where the feasibility of accessing and extracting this vast natural resource was finally demonstrated. It also discusses the numerous technical, administrative, and financial hurdles that had to be overcome along the way. This publication will no doubt prove invaluable to researchers around the world as they strive to move this now-proven technology toward commercial viability. In addition, it is a valuable source of relevant information for anyone interested in the world energy outlook for the 21st century and beyond.

This book was released on 1989 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preparation, execution, and analysis of a 30-day Initial Closed-Loop Flow Test (ICFT) of the Phase II reservoir were the primary objectives of the Hot Dry Rock Program in fiscal year 1986. The ICFT successfully tested the Phase II heat-extraction loop with the injection of 37,000 m3 of cold water and production of 23,000 m3 of hot water, extracting up to 10 MW/sub t/ when production reached 0.0139 m3/s at 192/degree/C. By the end of the test, water loss rate has decreased to 26% and a significant portion of the injected water had been recovered, 66% during the test and an additional 20% during subsequent venting. Geochemical, tracer, and seismic analyses suggest reservoir fracture volume was growing throughout the test. A new technique, the ''three-point'' method, was developed to determine locations and orientations of seismically active planes. Fault or joint planes are identified in what superficially appears to be an amorphous microearthquake location set. Five planes were determined when the three-point method was applied to a location data set for the massive hydraulic-fracturing experiment conducted in 1983. 23 refs., 19 figs., 3 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: During fiscal year 1981, activities of the Hot Dry Rock Geothermal Energy Development Program were concentrated in four principal areas: (1) data collection to permit improved estimates of the hot dry rock geothermal energy resource base of various regions of the United States and of the United States as a whole, combined with detailed investigations of several areas that appear particularly promising either for further energy extraction experiments or for future commercial development; (2) successful completion of a 9-month, continuous, closed-loop, recirculating flow test in the enlarged Phase I System at Fenton Hill, New Mexico - a pressurized-water heat-extraction loop developed in low-permeability granitic rock by hydraulic fracturing; (3) successful completion at a depth of 4084 m (13,933 ft) of well EE-3, the production well of a larger, deeper, and hotter, Phase II System at Fenton Hill. Well EE-3 was directionally drilled with control of both azimuth and inclination. Its inclined section is about 380 m (1250 ft) vertically above the injection well, EE-2, which was completed in FY80; and (4) supporting activities included new developments in downhole instrumentation and equipment, geochemical and geophysical studies, rock-mechanics and fluid-mechanics investigations, computer analyses and modeling, and overall system design. Under an International Energy Agency agreement, the New Energy Development Organization, representing the Government of Japan has joined Kernforschungsanlage-Juelich GmbH, representing the Federal Republic of Germany, and the US Department of Energy as an active participant in the Fenton Hill Hot Dry Rock Project.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential of energy extracted from hot dry rock (HDR) was investigated as a commercailly feasible alternate energy source. Run Segments 3 and 4 were completed in the prototype reservoir of the Phase I energy-extraction system at Fenton Hill, New Mexico. Results of these tests yielded significant data on the existing system and this information will be applicable to future HDR systems. Plans and operations initiating a Phase II system are underway at the Fenton Hill site. This system, a deeper, hotter commercial-size reservoir, is intended to demonstrate the longevity and economics of an HDR system. Major activity occurred in evaluation of the national resource potential and in characterizing possible future HDR geothermal sites. Work has begun in the institutional and industrial support area to assess the economics and promote commercial interest in HDR systems as an alternate energy source.
