Abstract: A resilient conductor having an outer flexible insulating coating and an inner flexible conducting core is employed in a drill string to maintain an electric circuit between a subsurface and surface location. The conductor is inserted in the drill string in a generally free-hanging, random fashion to store excess length of conductor which is utilized as the drill string is lengthened. The stored conductor can be maintained in the drill string in a generally untangled state due to its kink-resistant mechanical and physical properties. Moreover, the frictional drag of the flowing drilling fluid tends to straighten and disentangle the conductor.

Abstract: A multi-phase heated fluid process which avoids heated fluid breakthrough, is used to continually produce subsurface hydrocarbons, utilizing two commmunicating wells in a process comprising:Simultaneous injection of said heated fluid into said wells until substantial mobilization of hydrocarbons within a zone surrounding said wells is obtained; one well is shut in while production is commenced in the other well;Preferably a final phase where sufficient heated fluid at relatively restricted rates is continually injected into said one well to provide driving force for continual production in said other well, without interruption, once production has commenced.
