Endure greater tensile and compressive forces when perforating highly deviated and horizontal wells While known for being flexible, coiled tubing (CT) also delivers a rigidity and strength enabling greater tensile and compressive force endurance, which is a major operational advantage when perforating in highly deviated and horizontal wells or with longer gun strings. Additional gains in depth control are available by integrating a casing collar locator and gamma ray detector. Perform live well perforating CT perforating is ideal for live wells. Pressure control techniques are used to run long gun strings and either drop off or retrieve the guns without having to kill the well.
