Fraser, III, J M; Coronado, M P

A method is described of testing a packer in a well bore, the packer being of the type having an interior bore for conducting fluids and external gripping and sealing means for gripping and sealing against the surrounding well bore. The method comprises: first setting the packer at a desired depth within the well bore; thereafter lowering a test tool having a generally cylindrical exterior and an internal bore on a tubing string to engage the interior bore of the previously set packer. The test tool has an external collet carried thereon with collet fingers which are received within a recess formed in the interior bore of the packer for engaging the packer on the test tool; providing an external shear sleeve on the test tool, the shear sleeve being initially positioned to underlie the collet fingers when the collet fingers are received within the packer recess to thereby retain the packer on the test tool. The test tool is also provided with a port for communicating fluid pressure from the interior of the test tool for shearing the sleeve and releasing the collet fingers; testing the packer by supplying pressurized fluid on at least one side of the packer external sealing means; and in the event of a successful test, sealing off the internal bore of the test tool at a point below the internal port.
