Abstract

See full text

A work string tool to be operably associated with a weight-set packer tool uses pressure applied by fluid circulated from the surface above the weight-set packer, to deploy a hydraulic hold-down anchor mechanism above the packer to reduce the risk of unsetting during a high pressure “positive” wellbore integrity test. An axial bore of a tool tubular body houses first and second inner sleeves, and is configured to accommodate independent axial movement of the sleeves to provide multiple fluid flowpath configurations through the tool which allow use of circulation fluid pressure to circulate a ball obturator to a valve seat in a sleeve when a configuration change is required to deploy or release the anchor mechanism.
