  • Patent number: 10392902
    Abstract: A technique facilitates the anchoring and use of a downhole tool. The technique may be utilized with operations in which fluid is pumped or otherwise flowed through a tubular to the downhole tool. The operations are performed after the downhole tool has been fixed relative to the wellbore and while the tubular remains connected to the downhole tool. In some operations, the downhole tool is manipulated from the surface via the tubular to control placement of the fluid flowing down through the tubular.

  • Publication number: 20130180707
    Abstract: The current application discloses coiled tubing assemblies and methods of connecting coiled tubing with downhole devices. In an exemplary embodiment, the assembly comprises a coiled tubing, a downhole device for performing an operation in a subterranean wellbore, a connector that mechanically connects the coiled tubing to the downhole device; and a sealing device that seals the connection between the coiled tubing and the connector. The sealing device is substantially free of axial tensions caused by a weight of the downhole device.

  • Patent number: 7640983
    Abstract: The invention discloses a method of treating a zone of a well comprising a wellbore, a tube which is permeable to settable material, said tube forming an annulus with the wellbore; and wherein said zone is located in the annulus, the method comprises the steps of: (i) placing inside said tube a first plug; (ii) creating on said tube a first opening and a second opening, so that: the zone be located between said first and second openings and the first opening be located between said zone and said first plug; (iii) placing inside said tube a second plug, so that said second plug is located between said second opening and said zone; (iv) injecting a settable material inside said tube between said second and first plugs, so that settable material fills the annulus and the zone by passing through the first opening; and (v) eliminating said second plug.
