ABSTRACT:
A well pump suspended from a mandrel in a well which is run on a cable placed in tension after the pump supporting mandrel is landed. The mandrel is latched in the well and a much greater force is required to release the mandrel from the tubing than was required to move the mandrel to the latched position. The cable includes multiple wire drum sockets which are moved laterally into recesses in the supporting mandrel and held in place by a moveable sleeve. A space out is provided between the mandrel and the cable. The conductors of the cable are brought out of the space out structure to the exterior of the mandrel and extend down through a penetrator which forms a part of the mandrel. The space out structure, the connection between the space out structure and cable, and the mandrel and penetrator components, and the pump are all held against relative rotation to avoid damage to the conductors.
