Multi-function apparatus for adding a branch well sealed liner and connector to an existing cased well at low cost










Image Number 4 for United States Patent #6533040.

A multi-function apparatus designated as a "Liner Stub Assembly", run in and set in an existing cased well at the end of a work pipe string is used to add a liner-equipped branch well to an existing cased well in a way which provides full access to both wells. Pre-fabricated mobile straight tubular connectors (Liner Stubs) are installed and sealed by on-board explosive means which accurately cut a window of pre-determined shape and dimensions in the existing well casing and weld to it the Liner Stub's stop collar to make downhole a leak-proof tubular junction of the two wells, by means of such short connectors.
