The PACE®-X800 rig was the first to feature our proprietary Side-Saddle® design, which includes a 15-foot wide by 26-foot tall clearance that allows the rig to easily walk over existing wellheads. The perpendicular placement of the catwalk prevents interference with simultaneous operations on adjacent wells.
A Side-Saddle® rig is ideal for batch drilling because it can drill the surface along one row of wells, walk to the adjacent row and repeat the same tasks using the same drilling mud. As the rig moves along the line of wells, the catwalk and pipe do not interfere with wells in the same line or on adjacent rows, enabling simultaneous operations such as coiled tubing, offline cementing or casing running. Minimal flowline handling is required because the ancillary equipment moves with the rig, which allows the substructure to move more efficiently and across longer distances without issue.
Today, the vast majority of our Nabors SmartRig® and iRig® drilling systems feature our proprietary Side-Saddle® Substructures.
