ABSTRACT:
A method and apparatus for forming a heat exchange system in the earth. A curve hole is formed in the earth having a substantially constant radius of curvature and is cased to form a cased flowpath therethrough. The apparatus used for forming the hole is comprised of a trailer having a frame on which a plurality of drill pipe supports are pivotably mounted. A curve drill pipe is supported by said supports and is connected at one end to a pressurized drilling fluid source. The pipe is fed into the earth and the fluid exiting from the leading end cuts a hole in advance of the pipe. When the pipe has been fed completely through the earth and the leading end breaks the surface, the fluid is stopped and a casing is connected through an adaptor to the leading end of the pipe. The pipe is then withdrawn through the hole to draw the casing through the hole. The annulus between the casing and the hole is filled with a particulate heat conductive material as the pipe is withdrawn.
