Coiled tubing

Field Trial Achieves Post-Frac-Plug Drillout Using 2⅞-in. Coiled Tubing

This paper details a trial involving the deployment of a transportable coiled tubing (CT) unit capable of holding 30,000 ft of high-strength 2⅞-in. CT.

As unconventional basins continue to evolve, operators are drilling longer laterals and increasing both the number of stages during stimulation and the volume of material pumped. Coiled tubing (CT) must also evolve to reach extended depths and manage the growing volume of solids placed in the wellbore. The largest land unit ever built for North America, combined with one of the largest 2⅞-in. CT strings ever milled, has resulted in a transportable CT unit capable of holding 30,000 ft of high-strength 2⅞-in.
