GARD U-line™ Roller System for reducing cost and carbon impact of well-intervention

Page last modified
April 11 2024

GARD U-line™ Roller System is a novel, cost-effective and the world’s first all-in-one universal, modular and multifunction downhole conveyance roller system that services all types of operation whether it is slick-line, e-line, fiber or any other data cabling or tubing system.

The U-Line roller has a very low friction coefficient (less than 3%). This means extended reach in deviated wells (3x that of our competitors) and the proven ability to replace tractor systems. In less deviated wells U-Line has successfully reduced cable tension risks caused by wellbore obstructions. The tool is highly adaptable in that it can run both WL and SL, and the OD can be changed in the field by using different OD wheels.

 

Pros & Limitations
1
Low friction means TD can be reached without tractor even in high deviation wells
1
Only two chassis sizes to cover all casing sizes and restrictions
1
Can run on slickline, e-line or fiber with same roller
1
No screws or fasteners to reduce risk and maintain in the field
1
High clearance allowing centralisation of toolstring
1
Running jobs on slickline minimises operational footprint / carbon footprint
1
Operational team and software analysis provided
1
Global fleet means shorter/quicker logistics
0
Current fleet is mainly applicable for cased-hole not open-hole intervention (open-hole in development)
