Patent

CA 2444648

22 A self anchoring tool is disclosed that can be positioned downhole and used in casing. The tool has an architecture that supports installation by running downhole and into engagement with a groove formed in the casing, called the profile nipple. The tool readily supports use of weak materials such as plastic, for components of the tool that must be drilled to reopen the wellbore after cementing. As such, no restriction is needed in the casing for accepting or latching the tool and the portion of casing including the groove can be installed at the start of the drilling operation. In addition, the profile nipple can be used to engage other drilling tools and, therefore, can already be in place when the final well depth (TD) is reached.
