  • Coiled tubing pump down system
    Patent number: 9097084
    Abstract: A system and methodology facilitates an operation utilizing coiled tubing. The technique comprises coupling a hydraulic assist device to coiled tubing. A fluid is flowed into an enclosure such as a wellbore and along the coiled tubing. The fluid is flowed against the hydraulic assist device, and the action of this fluid against the hydraulic assist device creates a pulling force on the coiled tubing. The pulling force facilitates movement of the coiled tubing along the wellbore or other enclosure to provide the coiled tubing with greater reach for a variety of intervention operations or other types of operations.
