Abstract:
A system for delivering a downhole tubular from a rack at an oilfield surface to a rig floor thereat. The system includes a trough for accommodating the tubular that is slidably engaged with a lift frame in a sledded fashion. Thus, for delivery of the tubular, the trough may be sleddingly extended from the lift frame. That is, as opposed to a roller type of coupling between the trough and tubular, a sledded coupling is utilized that may require comparatively less maintenance and mobilization time. This may be particularly the case where lighter weight tubulars of less than about 1,000 lbs., preferably under about 500 lbs., are being delivered.
