ABSTRACT:
A side pocket mandrel arranged to receive a measuring instrument such as a pressure gauge in the open-bottomed side pocket thereof includes an electrical contact mounted at the top of the side pocket and connected to a cable extending upward to the surface, and an instrument lowered on a wireline kickover tool and inserted upward into the pocket and latched in place with a mating electrical connector automatically engaging the contact. Placement of the electrical contact at the top of the pocket prevents debris from settling around it and preventing reengagement after removal of the gauge for any reason.
