..., chemicals, and time than conventional milling operations. Novel swarf-less section milling turns conventional section milling upside down, milling the window from the bottom up. Milling in this manner allows for the use of a mechanical pump to drive all cuttings downhole. The cuttings can then be disposed...

... to operators. A key challenge faced when removing high volumes of casing (up to and exceeding 50 meters (165 ft.) per interval), is circulating the generated steel cuttings (swarf) out of the well, and safely capturing and disposing of them. Much of the time spent on section milling operations is dedicated...

... incorporating Coil tubing (CT) and e-line interventions concluded that standard milling operations would pose additional challenges for the well due to the design of the completion below the isolation valve. Subsequently, a unique, star shaped milling bit was designed and manufactured to enable milling...

... tubing. The system uses coiled tubing technology and blends the special techniques of both drilling and window milling operations using coiled tubing. Development details emphasized will be the overall system design, performance criteria and equipment evaluation. Introduction Sidetracking through...
