We offer an alternative solution to the demanding issues of deployment and retrieval of tubing, casing, and/or accessories. We utilize ball transfer systems to help manipulate equipment needing to reach trajectories that are difficult by standard means. The ball transfer systems allow 360° rotation in all directions, helping equipment maintain crucial momentum during movement. Redundancy in the system allows for smoother deployment and retrieval, plus maneuverability of assemblies.
| Reduces friction in all planes – vertical, horizontal, and diagonal |
| Reduces torque and drag continually |
| Helps maintain momentum due to spherical shape – allowing movement to area of least resistance |
| No axis (which can shear and add friction when not given into account) |
| Reduces wear and integrity damage to surface areas where the balls travel |
| Allows for more maneuverability of tools being deployed or retrieved |
The Adjustable Tension Centralizer Tool (ATCT) assists toolstrings in getting in and out of wells that require centralization. The ATCTs are versatile enough to accommodate proper placement along a toolstring or workstring. Since tubing and casing sizes and weight vary, the tools need to be flexible, adjustable, and rugged enough to withstand tough deviations while maintaining the ability to maneuver the toolstring or workstring. The mission of the ATCT is to allow toolstring or workstring to ease downhole, and back uphole utilizing a ball transfer system.
The Roller Sub Mule Shoe (RSMS) helps ensure integrity of packers and bridge plugs during their deployment. Mostly used in high deviated wells, the RSMS reduces friction and torque. It incorporates a ball transfer system allowing full rotation in all vertical, horizontal, and diagonal directions (360°). Conducted tests have shown to be effected in +80° deviated wells. It has also allowed ease with deploying packers and bridge plugs on horizontal wells where the equipment typically had to be pumped down the well. Completion of packer setting and bridge plug setting on electric line also reduces rig downtime and rig costs. It greatly reduces the need to run the equipment using the more expensive work strings and coiled tubing.
The Tubular Roller Sub (TRS) helps ensure integrity of tubing and casing during their deployment. Mostly used in high deviated wells, the TRS reduces friction and torque. It incorporates a ball transfer system allowing full rotation and movement in all vertical, horizontal, and diagonal directions (360°). Conducted tests have shown to be effected in +70° deviated wells. Its design allows full integrity without compromising pressure loss or the need to have external centralizers which can break or create fishing problems. Completion of reaching trajectory in a timely manner also reduces rig downtime and rig costs. It greatly reduces the need to run the equipment using weak bow spring centralizers and will shorten the time needed to run tubing or casing.
The Roller Shifting Tool provides centralization and flexibility while shifting a profile found in sliding sleeves and side doors. The RST utilizes a ball transfer system, which allows the outside (exposed) ball to roll and rotate against the inner balls. This reduces friction greatly, in comparison to traditional pressed-in ball bearings or bearings housed with racers. The RST removes the need for additional component centralizers, which only centralizes above or below the shifting tool. Since the RST has 3 ball transfers on the core and 3 on the cap, it allows centralization closest to the locating keys. This allows the springs behind the locating keys to exert the same force on both sides and also ensures a smoother shift. The RST is available in sizes of 1.85" (for 1.875" profiles); 2.250" (for 2.313" profiles); 2.700" (for 2.750" profiles), and 2.780" (for 2.813" profiles).
The Slickline Roller Stem Tool provides friction reduction, centralization, and flexibility while deploying and retrieving toolstrings. The SRST utilizes a ball transfer system which allows the outside (exposed) ball to roll and rotate against the inner balls. This reduces friction greatly, in comparison to traditional pressed-in ball bearings or bearings housed with racers. Since the SRST has 6 ball transfer systems on the tool, it allows centralization and the most dynamic flexibility. This allows debris to “roll” off the toolstring to continue in the momentum direction. This also ensures a smoother roll up or down the wells. The SRST provides friction reduction in all planes – vertical, horizontal, and diagonal. It also adds insurance when setting and retrieving plugs and other slickline tools run in the wells. The SRST is available in sizes of 1.25"; 1.500", and 1.750".
When a job requires specific equipment, Premium Drill Pipe has the solution. Tools can be customized and engineered upon request to meet the demands of each project. We collect vital information prior to engineering and design to ensure a safe and quality product. As with all of our products, we reestablish physics as the ultimate driving tool to enhance mechanical engineered products - not vice versa.
