“Can we perforate at 82? without using Coiled Tubing or a tractor?” “How can we retrieve a packer at 70??” “Can I cut costs by reducing the need for tractors and/or CT?” Wireline Engineering Ltd (and Wireline international LLC in USA) provides new answers to old questions with patented “Roller Bogies”. These tools enable wireline companies (electric and slick line) to successfully provide services including perforating / logging / surveying / intervention work at very high angles, by conveying tools with a virtually frictionless roller system. Documented case histories – 86? with slickline assemblies & 82? with electric line, cased hole only. Roller Bogies are now available in the U.S., based in Lafayette, Louisiana.
