Roller Bogie Technology

Roller Bogie® is the name on the world's best wireline conveyance solution.

Whether it's slickline of electric line, the frictional resistance imposed by increasing deviation or tortuous well profiles frequently makes wellbore access difficult or even impossible for conventional wireline toolstrings. These difficult operating conditions often mean certain wireline operations cannot be performed, requiring the use of coiled tubing or wireline tractors, neither of which comes without increased complexity - and a substantial price tag.

Wireline Engineering has developed a unique patented roller technology to meet this need and has engineered it into a family of innovative and functionally diverse products that allow wireline toolstrings to be run in tubing, casing or open hole with virtually no frictional drag. These proprietary products are equally adaptable to slickline or electric line toolstrings and offer a level of performance that consistently outclasses all other roller products.

Roller Bogie conveyance tools not only lift the toolstring on to large rollers, eliminating friction with the tubing but can also accommodate and transfer hydraulic, electrical or explosive systems - allowing complete flexibility for toolstring integration and optimum positioning.

These tools are readily serviced in the field and are extremely robust and reliable. No roller bogie tool has ever failed or lost components downhole.

The advantages brought by these tools are considerable.

Easier and deeper wellbore access
Reduced wireline pickup weights and reduced risk of wire failure
Protects toolstring components from frictional wear
Protects completion tubulars, especially plastic coatings and high chromium content
More constant logging speeds, avoiding erratic slip-stick and producing better data
Provides better weight transfer and allows more effective and visible jarring downhole
Can avoid the need for more costly and complex solutions such as tractors or coiled tubing
