Abstract
Aspects of the present invention provide a tubular handling system for handling wellbore tubulars. In one aspect, the present invention provides a tubular handling system adapted to retain a tubular without damaging the outer surface of the tubular. In another aspect, the present invention provides a method of connecting tubulars by remotely controlling the connection process, including joint compensation, alignment, make up, and interlock. In one embodiment, the tubular handling system comprises an elevator adapted to support a tubular utilizing a first portion of an upset of the tubular and a spider adapted to support the tubular utilizing a second portion of the upset. In another embodiment, at least one of the elevator and the spider is remotely controllable. In yet another embodiment, the tubular handling system comprising a joint compensator system adapted to provide fluid communication to the elevator during rotation of the tubular.
