Coiled tubing sidetrack: Slaughter Field case history
The paper describes the successful sidetrack of an oil well in the Slaughter Field in West Texas using coiled tubing (CT). Several first-time CT operations performed during this workover include: setting a whipstock in casing on CT; cutting a window with CT; using mud pulse measurement-while-drilling (MWD) with CT in a real well; use of a fluid-operated orientation tool for in-hole toolface changes; successful use of an autodriller to maintain weight on bit while drilling. Directional control of the sidetracked hole proved to be ineffective due to a surface software problem. The resultant wellbore was not horizontal as planned, but instead closely paralleled the original well for much of its length. However, the previously non-productive well flowed 1,000 barrels of fluid per day (BFPD) from the sidetrack following the workover.
