Abstract (en)

A system and related method for deploying an electric submergible pumping system within a wellbore comprises an electric submergible pumping system (20) with an electrical cable (32) operatively connected thereto. A plurality of sucker rods (28) are connected together to form a sucker rod string, with one end of the sucker rod string connected to the electric submergible pumping system. The electrical cable (32) is attached to the sucker rod string (28) at a plurality of spaced locations by clamping (34) or banding (36). This deployment system permits the use of relatively inexpensive and manoeuvrable rigs/cranes for the installation, removal and repair of the electric submergible pumping system rather than having to use conventional relatively expensive and large workover rigs. <IMAGE>
