Standard, Sour or Severe Sour Service available.

Connections available to suit customer specifications.

Features:

Self-orienting design
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 need for costly services such as coiled tubing or wireline tractors.
Deploy longer logging strings in deviated wells.

Protect high value equipment from frictional wear.
Improve cable management by reducing erratic loading.

With its long experience in conveyance solutions, Impact Selector’s unique patented Roller Bogie technology increases the safe operating envelope for wireline tools. Wireline can now be run safely at greater deviations than has previously been possible, before costly alternatives such as pipe conveyed logging needs to be considered.

The Roller Bogie is equally as effective in cased hole environments to extend wireline access for cement logging, plug setting and other cased hole operations with larger tools.

The roller body rotates freely around the mandrel which is connected to the host tool string. The high-lift roller design stands the tool string off the side wall to ensure maximum friction reduction and to manage the risk of differential sticking. Various size roller body sets can be supplied depending upon the hole, casing size and tool string lowercase outside diameter and are clamped around the mandrel, without the need for re-wiring.

With a large standoff to protect against differential sticking and high-lift rollers to eliminate friction; the Roller Bogie tool enables easier and deeper access with much reduced risk. Tools are available in a range of sizes, with connections for all major service company logging tools and can be re-sized without removal from the tool string.

Standard, Sour or Severe Sour Service available.

Connections available to suit customer specifications.

Features:

Self-orienting design
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.

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.
