M14-25429M/KH/81 ABSTRACT OF THE DISCLOSUREAn electrode device for electrically heating undergrounddeposits of hydrocarbons such as oil sand or oil shale. Pluralwell pipe sections are joined through insulated pipe joints withan electrode connected through one of the insulated pipe jointsto a lower one of the pipe sections. Each of the insulated pipejoints includes a first tubular member having a flange portionat one end thereof, a second tubular member having a cap portionat one end which is received in the flange portion of the firsttubular member with a gap therebetween, and an insulating memberdisposed in the gap for hermetically coupling the first andsecond tubular members and for electrically insulating firstand second tubular members from one another.
