Rig assist snubbing units provide economical means of running or pulling tubing in and out of wellbore under pressure, which allow operators to continue producing the well during intervention applications. Live well workover eliminates the risk of formation damage from kill fluid, as well as saving the time and expense of loading/unloading the kill fluids from the wellbore and costly disposal of the kill fluid.
KLX has one of the largest fleets of rig assist space saver and “mini” snubbing units currently working in the markets we serve. Through operational efficiency, integrity and industry expertise, KLX has established itself as a recognized leader in snubbing operations.
The expertise of the KLX snubbing personnel encompasses completions, production, and critical well operations:
KLX’s light-weight, compact “mini” hydraulic, rig assist units are mounted on gooseneck trailers for easy transportation and maneuverability on location. They come complete with diesel fuel power units, jack assembly with or without integral work platform, a pipe handling winch, 5,000 psi Shafer type annular stripping BOP, and most units come with a Cameron Type-U safety backup BOP. The units can safely handle tubulars up to 3-1/2” at maximum pressures of 1,500 psi and 2-7/8” and smaller tubing at 2,000 psi. Rig up is quick, usually within one hour or less.
KLX’s larger space saver rig assist units are mounted on bobtail trucks or semi-trailer units. The space saver snubbing unit has an eight to ten foot jack stroke for quick trip times under pressure. These units are equipped with the same 5,000 psi annular BOP as the “mini” rig assist units, but also utilize two Cameron type-U BOPs which allows for ram-to-ram stripping at pressures up to 6000 psi when the KLX proprietary pipe guide system is fitted into the snubbing jack assembly. A large work basket with power tongs and operators console allows for safe, efficient operation.
