Abstract:
A four-cornered, open frame, connected either to a top drive or to a traveling block, has an elevator at its lower end used to support the weight of the tubular string, and has a mud tool, a stabber, a guide, a spinner, a tong, a stabbing guide and a backup tong carried by the frame. A manipulator arm picks up a horizontal tubular, manipulates the tubular to vertical, and moves the tubular into the interior of the frame, allowing the tubular to be made up in the string while the string is being lowered into the wellbore.
