4.3 Fenton Hill Chapter 4 Review of EGS and Related Technology – Status and Achievements 4.3.1 Project history The project at Fenton Hill was the first attempt anywhere to make a deep, fullscale HDR reservoir. The site – on the edge of the Valles Caldera at the northern end of the Rio Grande rift zone in north central New Mexico – was chosen for its heat and rock characteristics, as well as its proximity to the Los Alamos National Laboratory where the project was conceived. The purpose of the project was to develop methods to extract energy economically from HDR systems located in crystalline, granitic/metamorphic basement rock of suitably high temperature. The R&D program was roughly divided into two major phases. Phase I, starting in 1974 and completed in 1980, dealt with field development and associated research on a 3 km deep reservoir with a temperature of about 200°C. Phase II followed in 1979, with the drilling of EE2 into a deeper (4.4 km), hotter (300°C) reservoir. Figure 4.2 shows a map of the site and some characteristic properties of the formation and stimulated reservoirs. The first deep well drilled at Fenton Hill, called GT2, was started on February 17, 1974, and was completed to a temporary depth of 2,042 m in September 1974. Following the completion of the well, a series of hydraulic fracturing tests was run, and completed in early October of 1974. After these tests were completed, the well was deepened to 2,932 m. Bottomhole temperatures (BHT) were about 180°C. The second deep hole drilled at Fenton Hill was Energy Extraction Hole 1 (EE1). EE1 was drilled from May 1975 through October 1975, to a total depth of 3,064 m and with a similar BHT as GT2. Additional hydraulic fracturing was then performed, but the reservoir connecting the wells was deemed inadequate. It was determined that additional fracturing would likely not create the desired reservoir connection. As a result, it was decided to directionally redrill one of the wells into the fracture system created by the other. In 1977, an attempt to establish a highpermeability flow path between the two was performed on GT2, at approximately 2,500 m (GT2A), and was also determined to be inadequate. The lower part of GT2A was then cemented in May 1977; and another hole, named GT2B, was directionally drilled out of the upper portion of GT2A at around 2,530 m. An acceptable connection was made between GT2B and EE1 at 2,673 m, with an average separation between the two boreholes of 100 m. Figure 4.3 shows the wells in vertical profile with the stimulated fracture zone shown in hatching (Tester and Albright, 1979). 47PDF Image | Review of EGS and Related Technology
