摘要： A method of creating a zonal isolation above a target zone in an underground wellbore comprises: inserting a slurry injection tubing into the wellbore; arranging within an annular space surrounding said tubing an particle accumulation means, such as an expandable screen or an area where the slurry velocity is reduced; and pumping a slurry comprising a carrier fluid and granular material down via the slurry injection tubing and the target zone and then up into the annular space, such that at least some granular material accumulates and forms an elongate zonal isolation in the annular space between the target zone and the particle accumulation means, which zonal isolation is removable and exerts a limited radial force to the surrounding formation, thereby reducing the risk of formation damage.

摘要： A method is provided for activating a downhole system arranged in an annular space formed between a radially expandable tubular element extending into a borehole formed into an earth formation and a cylindrical wall surrounding the tubular element. The downhole system is arranged so as to be activated by movement of an annular movement device along the tubular element. The method involves arranging the annular moving device around the tubular element, the moving device having an inner diameter slightly larger than the outer diameter of the tubular element in its unexpanded shape, and gradually expanding a portion of the tubular element by moving an expander through the tubular element in the direction of the moving device, whereby a transition zone of the tubular element is defined between the expanded an unexpanded portions of the tubular element. Upon contact of the transition zone with the moving device, continuing movement of the expander through the tubular element causes the moving device to move in axial direction along the tubular element whereby the moving device activates the downhole system.

摘要： A wellbore system comprises a borehole formed in an earth formation, the borehole having a borehole section containing a volume of gravel pack particles and at least one body of a swellable material. Each body of swellable material is adapted to expand from an unexpanded state to an expanded state upon contact of the swellable material with a selected fluid, wherein a flow passage is present in said borehole section allowing fluid to bypass the volume of gravel pack particles when the body of swellable material is in the unexpanded state. The body of swellable material is arranged to substantially close the flow passage upon expansion of the body of swellable material to the expanded state.

摘要： A method is disclosed of creating an annular seal around a tubular element for use in a wellbore. The method comprises providing at least one seal layer of a flexible sealing material susceptible to swelling upon contact with a selected fluid, the seal layer having a first edge and a second edge, and helically winding each seal layer around the tubular element so that the first and second edges extend opposite each other along the tubular element and so that the first and second edges seal relative to each other upon swelling of the flexible sealing material. The tubular element is lowered into the wellbore, and the selected fluid is allowed to contact each seal layer so as to induce swelling of the flexible sealing material whereby the first and second edges seal relative to each other.
