Abstract
An electrode well extending into a subterranean formation containing viscous hydrocarbons comprising a plurality of electrode tubes which are formed by extension of an elongated tube from the surface above the formation using a coiled tube injection unit or lowering the tubes on drill pipe, diverting the tubes radially outwardly from the wellbore into the formation and penetrating the formation with the electrode tubes using hydraulic jetting action by pumping fluid through the tubes during the insertion process. The tubes are installed axially spaced apart using respective tube guide members which are inserted into the wellbore and operate to form a curved path for diverting the tubes into the formation during the insertion process and for supporting the end of the tube after its insertion into the wellbore. Electrical contact is established between the plural tubes and their support members by the insertion of a length of tubing into the wellbore including a connector member at the distal end thereof, and which is connected to one end of the electrode tube support assembly.
