ABSTRACT:
A tool for pressure testing flow conductors. The tool can engage the inside wall of a flow conductor at any location and form a pressure barrier to allow hydrostatic testing of the flow conductor on one side of the tool for leaks. The tool can be used to test either vertical or horizontal flow conductors. The tool is particularly adapted for use with pumpdown or through the flowline (TFL) servicing equipment for hydrostatic testing of tubing in wells. The tool is initially inserted into the flow conductor in a retracted condition. The tool can be moved through the conductor as desired until activated at a selected position within the flow conductor.
