Abstract
The second phase of the Hot dry Rock (HDR) Geothermal Development at Fenton Hill, New Mexico, consists of two boreholes, inclined at an angle of 35°, with a vertical separation of 365 m (1200 ft). The two boreholes will be connected by 12 to 15 vertical parallel fractures to make a geothermal reservoir calculated to produce 20 MW(e) for 20 years. Accurate temperature measurements, borehole caliper logs, and directional surveys are require for the successful development operation of this man made system. Obtaining these data is extremely difficult because of the bottom hole static temperature of 335°C (635°F) at a depth of 4660 m (15,289 ft), the 35° deviation, the abrasive formation, and the presence of sticky drilling residue products.
