ABSTRACT:
A packer actuated vent assembly comprising an outer barrel attached to a packer body, and a mandrel extension attached to the lower end of the mandrel of the packer. A valve means on the mandrel extension has a slidable valve element which slidably engages a medial portion of the outer peripheral surface of the mandrel and normally is in the opened position. The valve element has a boss thereon which engages a shoulder on the barrel and is thereby moved from the opened to the closed position when the packer mandrel, and therefore the mandrel extension, is properly manipulated to seat the packer. This combination of elements enables a tubing string to be run downhole into a borehole with the tubing string in the open configuration, so that fluid contained within the annulus flows through the opened valve means into the tubing string, thereby balancing the fluid pressure on either side of the tubing string; and when the packer is set, the interior of the tubing string is isolated from the borehole annulus.
