Book excerpt: Early attempts to hydraulically fracture and connect two wells drilled at the Hot Dry Rock site at Fenton Hill in New Mexico failed. Microearthquakes triggered by hydraulic fracturing indicated that the fracture zones grew in unexpected directions. Consequently one of the wells was sidetracked at a depth of 2.9 km; was redrilled into the zones of most intense microseismic activity; and a flow connection was achieved. Hydraulic communication was improved by supplemental fracturing using recently developed high temperature and high pressure open hole packers. Preliminary testing indicates a reservoir with stimulated joint volume which already surpasses that attained in the earlier phase I reservoir after several years of development. 12 refs., 6 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.

Book excerpt: Two wells, GT-2 and EE-1, were originally drilled to a depth of 9600 ft (2.93 km) and 10,000 ft (3.05 km), respectively, and, after some difficulties, including redrilling of the bottom portion of GT-2, a good fracture connection was made between EE-1 and GT-2B, as the modified GT-2 was called. The circulation system was studied extensively for the purpose of establishing a number of fracture properties. Techniques were developed to determine orientation, geometry, heat exchange area, volume, flow impedance and impedance distribution. A much larger fracture system was then created from a depth of 9620 ft (2.93 km) in EE-1. The techniques used and results obtained in the study of the new and old fracture systems are discussed.

Book excerpt: The Phase II system has been created with a series of hydraulic fracturing experiments at the Fenton Hill Hot Dry Rock site. Experiment 2032, the largest of the fracturing operations, involved injecting 5.6 million gallons (21,200m3) of water into wellbore EE-2 over the period December 6-9, 1983. The experiment has been modeled using geothermal simulator FEHM developed at Los Alamos National Laboratory. The modeling effort has produced strong evidence of a large highly fractured reservoir. Two long term heat extraction schemes for the reservoir are studied with the model.

Book excerpt: Extended flow testing at the Fenton Hill Hot Dry Rock (HDR) test facility concluded in Fiscal Year 1993 with the completion of Phase 2 of the long-term flow test (LTFT) program. As is reported in detail in this report, the second phase of the LTFT, although only 55 days in duration, confirmed in every way the encouraging test results of the 112-day Phase I LTFT carried out in Fiscal Year 1992. Interim flow testing was conducted early in FY 1993 during the period between the two LTFT segments. In addition, two brief tests involving operation of the reservoir on a cyclic schedule were run at the end of the Phase 2 LTFT. These interim and cyclic tests provided an opportunity to conduct evaluations and field demonstrations of several reservoir engineering concepts that can now be applied to significantly increase the productivity of HDR systems. The Fenton Hill HDR test facility was shut down and brought into standby status during the last part of FY 1993. Unfortunately, the world's largest, deepest, and most productive HDR reservoir has gone essentially unused since that time.

Book excerpt: The Hot Dry Rock (HDR) concept is a simple one. Two nearly parallel wells are drilled, and hydraulic fractures are then formed to hydraulically connect the wells. Water pumped down the injection well and through the fracture system is heated by contact with the hot rock and rises to the production well. This hot fluid is passed through a heat exchanger at the surface and the extracted heat is used for direct heating or electricity generation. The cooled production fluid is then reinjected, thereby setting up a circulation loop. This paper describes the development and execution of the HDR project at Fenton Hill, New Mexico.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The results of a long-term (286 day) flow test of the second hot dry rock reservoir at the Fenton Hill field site are presented. This second reservoir was created by fracturing an interval of granitic rock located at a depth of 2.93 km (9620 ft) in the same wellbore pair used in the creation of the first, smaller reservoir. The new fracture system has a vertical extent of at least 320 m (1050 ft), suggesting that the combined heat-transfer area of the old and new fracture systems is much greater than that of the old system. The virgin rock temperature at the bottom of the deeper interval was 197°C (386°F). Downhole measurements of the water temperature at the reservoir outlet, as well as temperatures inferred from geothermometry, showed that the thermal drawdown of the reservoir was about 8°C, and preliminary estimates indicate that the minimum effective heat-transfer area of the new reservoir is 45,000 m2 (480,000 ft2), which is six times larger than the first reservoir.
