ABSTRACT:
A resettable downhole packer is provided. Circulation from the surface creates a backpressure behind the packing element that expands the packing element into contact with the wellbore or casing. The tool may be shifted to trap pressure behind the element to retain it in contact with the wellbore or casing while, at the same time permitting flow through the packing element for procedures such as injection or stimulation. The tool incorporates a release mechanism to facilitate retrieval of the tubing string if, for any reason, the tool becomes stuck. Provisions are incorporated into the design to maintain the packing element in a retracted position for the running in and removal to avoid damage to the packing element.
