Apparatus for completing a subterranean well and associated methods of using same

摘要

A method of completing a subterranean well to provide access to a portion (38) of a parent wellbore (12) which has been closed off by a lateral wellbore liner (28). The method includes the steps of depositing cement (50) in the lateral wellbore liner (28) and then drilling through the cement (50) and liner (28). The cement (50) provides lateral support for a cutting tool (56) while it is milling through the liner (28).
