WIRELINE ABRASION FIELD TEST

DOWNHOLE TECHNOLOGY LTD, ABERDEEN, SCOTLAND, 1996

Wireline abrasion field trials were conducted for a major oil company at a test well site in Aberdeen, Scotland. DUOLINE 20 was installed in the dogleg section of a highly deviated tubing string along with coated tubulars from various manufacturers. A total of 27-slickline tool runs and 8-braided line logging runs were made with aggressive wireline speeds to diagnose coating/lining failures as they occurred. While instances of catastrophic coating failures were recorded on IPC joints after initial runs, only minor cosmetic damage to the DUOLINE string resulted after all runs were completed.
