Abstract: A setting tool for hanging a tubular string includes: a mandrel 60m having an upper portion and a lower portion for extending into the tubular string; a housing 65 connected to the mandrel upper portion; and a bonnet 51. The bonnet is: for receiving an upper end of the tubular string, disposed along the mandrel 60m, and linked to the housing 65. The setting tool further includes: an actuator 69 for stroking the bonnet 51 relative to the mandrel 60m and the housing 65, thereby setting a hanger 15h of the tubular string; an electronics package 66 in communication with the actuator 69 for operating the actuator in response to receiving a command signal; and a latch 62.

Abstract: The present invention relates to a downhole completion system for being arranged in a wellbore, comprising several casing sections having a casing length of 10-14 metres mounted as one well tubular metal structure by means of casing collars, wherein a number of the several casing sections each comprises at least three annular barriers each comprising an expandable metal sleeve configured to be expanded to abut the wellbore, the annular barriers of each casing section having a common longitudinal extension of at least 50% of the casing length. The present invention also relates to a downhole method for completing a well having a wellbore.

Abstract: The present invention relates to a downhole expandable tubular to be expanded in a well downhole from a first outer diameter to a second outer diameter for abutting against an inner face of a casing or borehole, the downhole expandable tubular having an outer face and a longitudinal extension, and comprising at least one first circumferential edge and at least one second circumferential edge provided on the outer face and spaced apart in the longitudinal extension, wherein a sealing element and a split ring-shaped retaining element are arranged between the first and second circumferential edges, and wherein the split ring-shaped retaining element has more than one winding, so that when the expandable tubular is expanded from the first outer diameter to the second outer diameter, the split ring-shaped retaining element partly unwinds. Furthermore, the present invention relates to an annular barrier.

Abstract: A technique facilitates formation of a burnished region, e.g. a seal region, via plastic deformation of an internal surface. The technique utilizes a burnishing assembly which may comprise a stem sized for insertion into a tubular region. The stem may be combined with an actuator and a plurality of rolling elements mounted on the actuator. When the actuator is actuated to a radially outward position, the plurality of rolling elements may be moved into engagement with the internal surface until plastic deformation occurs. The stem may then the rotated to force the plurality of rolling elements along the internal surface so as to form a region of plastic deformation. The plastic deformation may be located to form a seal, for example, between adjacent components.

Abstract: A method for expanding a lower bell section of an expandable tubular to a larger diameter than upper parts thereof utilizes an expandable bell cone (1) with circumferentially spaced segments (2) that expand in response to axial force and automatically retract in response to removal of the axial force, wherein gaps (A) are present between the expanded segments (2) and the tailends (2A) at the gauge of the segments are slightly skewed to mitigate the effect of the gaps (A) on the flattening of the expanded bell sections between the segments (2).

Abstract: A running tool for deploying a tubular string into a wellbore includes a tubular body and a latch for releasably connecting the tubular string to the body. The latch includes a longitudinal fastener for engaging a longitudinal profile of the tubular string and a torsional fastener for engaging a torsional profile of the tubular string. The running tool further includes a lock movable between a locked position and an unlocked position and the lock keeps the latch engaged in the locked position. The running tool further includes an actuator operable to at least move the lock from the locked position to the unlocked position and an electronics package in communication with the actuator for operating the actuator in response to receiving a command signal.
