Near-Term Developments in Geothermal Drilling
The DOE Hard Rock Penetration program is developing technology to reduce the costs of drilling geothermal wells. Current projects include: R & D in lost circulation control, high temperature instrumentation, underground imaging with a borehole radar insulated drill pipe development for high temperature formations, and new technology for data transmission through drill pipe that can potentially greatly improve data rates for measurement while drilling systems. In addition to this work, projects of the Geothermal Drilling Organization are managed. During 1988, GDO projects include developments in five areas: high temperature acoustic televiewer, pneumatic turbine, urethane foam for lost circulation control, geothermal drill pipe protectors, an improved rotary head seals.
