PowerTrac® Cone Crusher™ Scale Mill Concept
The industry has searched for an answer to removing wellbore scale build-up for years. Aker Kvaerner Well Service dedicated a significant amount of engineering effort to help solve this issue. The result: the development and commercialization of the Cone Crusher™ scale mill tool.
The Cone Crusher assembly, run in conjunction with the PowerTrac® Advance™ (PTA) wireline tractor, is set up with a special rotation adapter, mill gear and shock absorber for weight-on-bit control. The PTA tractor wheel section can be utilized as an anchoring device in vertical sections and an anchoring and forward thrust device in horizontal sections of the well. The Cone Crusher technology is based on a robust design where a main body with four cutting cones are rotating. Each cutting cone is free-rotating in its own axis independently of the main body RPM. Each cone has a unique cutting pattern, which crushes the scale, allowing the flow of oil or gas to resume.
By running the Cone Crusher scale mill tool, operators have a valuable addition to the available methods for scale removal, especially in extended-reach and horizontal wells. The tool is an effective intervention method to restore well productivity and can be a cost-effective alternative to coiled tubing services.
