Abstract
A system and methodology facilitates extending the reach of coiled tubing during a well operation. The technique employs tubing which is deployed along wellbore. A plurality of extended reach devices is positioned along the tubing. Each extended reach device has at least one internal guide member oriented for extension into an interior of the tubing. The guide member engages and guides the coiled tubing during movement of the coiled tubing along the interior of the tubing, thus enabling an extended reach during a wellbore servicing application.
Claims20
A system for extending the reach of coiled tubing during a well operation, comprising:
- a completion string deployed along a wellbore;
- and
- a plurality of extended reach devices positioned along the completion string, to facilitate extending the reach of the coiled tubing during movement of the coiled tubing along the interior of the completion string.
A method for extending the reach of coiled tubing during a well operation, comprising:
- positioning a plurality of extended reach devices along a completion string;
- deploying the completion string and the extended reach devices along a wellbore;
- and
- using the plurality of extended reach devices to support coiled tubing against buckling and to provide a low friction surface against which the coiled tubing moves longitudinally as the coiled tubing is conveyed along an interior of the completion string.
A wellbore system, comprising:
- a plurality of extended reach devices positioned at predetermined locations along a completion string deployed in a well to extend the reach of a conveyance deployed through an interior of the completion string.
