ABSTRACT:
A plugging apparatus for a gravel packer. The apparatus includes a plug comprising an operating mandrel slidably received in an outer mandrel. A collet is positioned on the outer mandrel. Actuation of the operating mandrel allows engagement of the collet with a threaded portion in the packer for locking the collet into such engagement. The plug is positioned in the packer and actuated to a locking position by use of a setting tool which has a portion press fit on a ring spring mounted on the operating mandrel. Once the collet is in the locked position, the setting tool may be removed from the ring spring. The plug may be retrieved by a retrieving tool which has a collet which engages the ring spring. The retrieving tool is used to actuate the operating mandrel to disengage the collet from the threaded portion of the packer and then to retrieve the plug from the packer.
