Abstract

An adaptor is mounted on a wellhead and includes an access port positioned vertically above the wellbore, a lateral passage, and a port offset from the wellbore and communicating with the wellbore via the lateral passage, on which a conventional Christmas tree is mounted. The Christmas tree is offset from the axis of the wellbore so that the wellbore can be accessed directly through the access port without disturbing the Christmas tree. The novel assembly allows full bore well intervention without oversized valving.
