Abstract

See full text

A pipe retriever for retrieving an unsecured pipe has a head connectable to a drilling pipe and defines a longitudinal axis. The longitudinal axis of the head is arranged substantially parallel to a longitudinal axis of the drilling pipe when connected. A tail extends from the head at an angle with respect to the longitudinal axis. The tail defines a hook shape having inward and outward surfaces. The inward hook surface defines a pipe recess sized to receive the unsecured pipe.
