A differential pressure-operated blanking completion tool for use at a Y- Block with an electrical submergible pump (ESP) in oil or other wells. The tool has a body having an inlet and first and second outlets, the outlets being arranged in parallel and opposite the inlet; a support member located between the outlets; a sealing element mounted on the support member and rotatable with respect to the support member, the element including a substantially spherical surface; and wherein the support member is pivoted between the outlets to bring a fresh sealing surface into contact with either outlet and thereby selectively seal the respective outlet and prevent fluid flow therethrough. |
