AbstractDuring the last decade, wireline tractors have replaced coiled tubing or snubbing for the conveyance of wireline logging and intervention equipment into horizontal or highly deviated wells.Based on this trend towards lighter and more mobile intervention methods, new techniques and equipment have now been developed to enable PowerTrac Advance (PTA*) wireline tractor technology to deploy rotating equipment such as milling, honing and brushing.Wells suffering from scale buildup or seal bore damage have been successfully recovered, leading to considerable cost savings compared to conventional methods.The wireline conveyed rotation technology can be used equally well in vertical pipe sections, as well as in horizontal or highly deviated well bores.There are operational limitations as to what can be achieved and proper job planning is important to assure success.
