BOTTOM HOLE ASSEMBLY RETRIEVAL FOR CASING-WHILE-DRILLING OPERATIONS USING A TETHERED FLOAT VALVE

摘要

A bottom hole assembly tor a casing-while-drilling operation utilizes a tethered float valve to retrieve the bottom hole assembly after the casing string has been positioned at a desired wellbore depth. The present disclosure relates generally to casing-while-drilling ("CWD") operations and, more specifically, to systems and methodologies that use a tethered float valve to retrieve the bottom hole assembly during a CWD operation.
