    Abstract: Det beskrives fremgangsmåter og apparater for ekspandering av nedihullsrør. I én utførelse beskrives en fremgangsmåte for ekspandering av rør, hvilken omfatter å tilveiebringe en sammenstilling (40) som omfatter en seksjon av ekspanderbart rør (42) og en ekspansjonsanordning i form av en ekspansjonsdor (44) plassert i det minste delvis utenfor røret (42), å kjøre sammenstillingen (40) inn i en borehull, Å forskyve ekspansjonsdoren (44) i forhold til røret (42) for å ekspandere en endeseksjon av røret (42) og ytterligere å forskyve ekspansjonsdoren (44) i forhold til røret (42) for å ekspandere en ytterligere seksjon av røret (42).

    Abstract: There is disclosed an expandable seal for sealing at least part of a wall of a well borehole, an expandable seal assembly comprising at least two such expandable seals, and a method of sealing at least part of a well borehole using such a seal. In one embodiment, the expandable seal ( 32 ) comprises an expandable tubular support member ( 34 ) and an inflatable seal element ( 36 ) mounted externally of the expandable tubular support member ( 34 ) for inflation radially outwardly into sealing engagement with at least part of a wall ( 50 ) of a well borehole ( 10 ). There is also disclosed a sealing apparatus for sealing at least one flow port in an expandable downhole tubular, in one embodiment, the sealing apparatus ( 332 ) comprising a sealing member ( 384 ) coupled to an expandable tubular ( 334 ), the sealing member ( 384 ) including a deformable portion ( 387 ) movable between a closed position preventing fluid flow through a flow port ( 356 ) and an open position permitting fluid flow through the flow port ( 356 ).

    Abstract: A method of expanding a tubing 20 by using a multiple stage expansion process comprises an assembly 24 having an expansion device 28 located at least partially externally of the tubing 20; running the assembly 24 into a casing 22 of a wellbore; translating the expansion device 28 relative to the tubing 20 to expand an end section of the tubing 20; and further translating the expansion device 28 to expand a remaining section of the tubing 20. In an embodiment, a packer 32 is provided for anchoring and sealing the tubing 20 against the casing 22, and a hydraulic jack (34, figure 4) is used to translate the expansion device 28.

    Abstract: There is disclosed a method of lining a drilled bore ( 10 ) and bore-lining tubing ( 12 ). The method comprises providing a first tubular ( 16 ); locating the first tubular ( 16 ) in the bore ( 10 ); providing an expandable, second tubular ( 22 ); locating the second tubular ( 22 ) in the bore ( 10 ) overlapping the first tubular ( 16 ); expanding a portion ( 24 ) of the second tubular ( 22 ) to create a coupling ( 29 ) including a flow passage ( 26 ) between the first tubular and the second tubular ( 16,22 ).

    Abstract: A method of isolating a section of a drilled bore containing a problem zone comprises: providing a section of tubing; locating the tubing in the section of the bore; and expanding the tubing and forming at least an outer portion of the tubing to conform to irregularities in the bore wall, to isolate the problem zone. The tubing may feature a formable outer section, and the expansion of the tubing may be achieved using a compliant rotary expander.
