Tractor Assist

Impact Selector's Roller Bogies make long horizontal logging easier on wireline. Significantly reduce static and dynamic pick up weights off bottom. Reach further under gravity before tractoring and lower total tractor force required, all of which can be demonstrated and quantified by pre-job modeling.

Cased Hole Roller Bogie

Inline roller system providing industry leading friction reduction for logging tools in cased hole. Allows wireline services to reach further in deviated wells and increases data quality through smoother movement.

      Impact Selector’s E-Line Roller Bogie tool is designed to reduce frictional resistance and enable access to high deviations. With a proven track record of success at inclinations up to 87 degrees and at depths in excess of 25,000 feet, the Roller Bogie tool is extremely robust, reliable and widely used in over 50 countries across six continents.

      Cased Hole E-line Roller Bogie tools are available in monoconductor, multiconductor, and perforating configurations and can be used in virtually all electric-line operations.

      Roller Bogie tools can be installed at any point in the tool string and lift the string on to highly efficient rollers, eliminating contact friction and allowing easier and deeper wellbore access.

      The roller body rotates freely around the mandrel which is connected to the host tool string. The unique body shape ensures the rollers are at all times oriented to the low side of the tubing.

      E-line Roller Bogie tools are available in a wide range of sizes to pass through all wellbore restrictions and can be ordered with a choice of connection types to suit individual tool string requirements, including profiled bullnose guides when run at the bottom of wireline tool strings.

      • Low friction dual rollers

      • Streamlined profile

      • Robust and durable tool design

      • Low maintenance requirements

      • Available for all tubing sizes

        Benefits:

        • Reach extended depths and higher deviations without the need for costly services such as coiled tubing or wireline tractors.

        • Lower pickup weight means reduced wire loading.

        • More effective and visible jarring at greater depth or higher deviation due to efficient transfer of mass.

        • Maintain completion integrity by protecting coated and high-chrome tubulars.

        • Improve data quality by eliminating stick-slip and achieving more constant logging speeds.

          Operators can perform the work using the same equipment without changing wireline operating procedures resulting in time savings with less risk. This is the most efficient conveyance system available for deviated intervention work when used in conjunction with E-line, slickline and other Roller Bogie tools.

          Used in most wellbore conditions, up to 87° deviation, Guide Roller Bogie tools are installed on the bottom end of the tool string.

          With independent swiveling, the self-orienting roller body ensures the rollers are oriented at all times to the low side of the tubing. The tool string is lifted onto large, highly efficient rollers, eliminating contact friction and enabling easier and deeper wellbore access. Running weight remains positive and steady; pick-up weight is greatly reduced and the risk of wire breakage is lowered.

          Guide Roller Bogie tools are available in a wide range of sizes to pass through all wellbore restrictions and can be ordered with a choice of connection types to suit individual tool string requirements.

          Features:

          • Ballistic durable with sealed bearings

              Benefits:

              • Lifting force placed at tangent reduces contact with the bore wall.

              • Creates standoff which significantly reduces abnormal contact friction.

              • Reduces fishing operations by 90%

                I-Wheels can be placed anywhere along the tool string. I-Wheels create low contact areas that keep the tool body off the low side of the bore wall, with a gap to pass over problem areas. They are efficient, consistent, and reliable tools in highly deviated wells up to 84° and reduce modelled friction by up to 80%.

                Cased Hole I-Wheels are routinely used to convey perforating guns. They can be placed above, below, or between gun sections, with the detonating cord run through the mandrel. They allow the gun to rotate independently of the wheels, assisting on the orientation of shot in high-or low side perforating.

                A wide range-of I-Wheel designs are available for any tubing, casing, or borehole size. Optional in-line or over-body-variants enable the best tool configuration tor optimum deployment. Custom-engineered sizing and bespoke mounting vadants are developed by Impact Selector upon request to suit specific applications and well conditions. Environmental Specifications

                      • Operational limitations.

                        As an integral part of Impact Selector’s Intelligent Conveyance Solutions, pre-job modeling provides the service company and operator with insights into optimum tool string design, wire selection and other operational fundamentals.

                        The results of pre-job modelling such as availability of overpull at target depth can be used to calculate the best setting for an open or cased hole wireline jar to avoid accidental firing when pulling out of hole, but ensure the jar will fire before maximum pull at surface is reached.

                        Impact Selector has conducted in-house testing to measure the friction reduction capabilities of our Roller Bogie and I-Wheel tools when strategically placed along any wireline tool string. When the results of these tests are combined with the ability to reduce the resistive frictional forces of independent tools in a computer model the output clearly demonstrates and quantifies the benefits of roller systems.
