A cable duct device in a swellable packer, in which the swellable packer is provided with at least one opening therethrough which is adapted to constitute a duct for a cable.

Cable duct device in a swelling packer

A method and a device for sealing a void incompletely filled with a cast material, in which an expandable material is placed in the void which is to be filled with a cast material, the expandable material expanding, when expanding after the cast material has cured, into spaces which are not filled with cast material.

Well tools utilizing swellable materials. Actuators for well tools may incorporate swellable materials as force generating devices. A well tool includes an actuator which actuates the well tool in response to contact between a swellable material and a well fluid. A method of actuating a well tool includes the steps of: installing a well tool including an actuator; contacting a swellable material of the actuator with a well fluid; and actuating the well tool in response to the contacting step. A well system includes a well tool with a flow control device and a swellable material. The well tool is operative to control flow through a passage of a tubular string in response to contact between the swellable material and well fluid.

Well tools with actuators utilizing swellable materials

A method and device for making lateral openings out of a wellbore in a well formation where fluid is made to flow through a motherbore tubular like a completion or production pipe and then through a needle pipe that is aimed at the formation, and where the method includes positioning a needle pipe that comprises at least one pipe section inside or outside a motherbore tubular; and arranging the at least one pipe sections to be telescopically displaceable with regard to an other pipe.

A method for removing at least a portion of an object in an annulus formed between an external surface of a tubular element and a wall surface. A method for removing an annulus packer, of the swellable type or the foam type, from an annulus in a wellbore comprises the placement of a jetting tool inside the tubular element and effecting a high-pressure fluid flow from the jetting tool to the object, whereby the object is removed.

A packer-anchoring device between an annular packer and a body, wherein the annular packer is provided, at least at one of its end portions, with an expandable end ring.

Packer-anchoring device

A method and a device for solvent injection in a subsurface well () where the solvent flows towards the formation wall () of the subsurface well () via a releasable duct ().

The invention refers to a device for sealing an annular space formed between an outer cylindrical element () having an end closure () and an inner pipe () extending within the outer element and having a free end. The invention incorporates a packer element () being slidably disposed around said pipe (), an actuation element () adapted for telescopic assembly around the outer surface of the pipe () and slidable from a first position to a second position, a conical ring () adapted for installation on the pipe (), where the actuation element () comprises an abutment element () designed for abutment against said packer (), and an actuation pipe () extending beyond the pipe () first end when the actuation element () is in said first position. The invention also refers to a method for sealing the annular space.

Method and device for setting a bottom packer

A method and a device for sealing a void incompletely filled with a castable material, in which an expandable material is placed in the void which is to be filled with the castable material, the expandable material expanding into spaces which are not filled with cast material. A method of sealing an annulus in a borehole includes the steps of: positioning an expandable material on a tubular structure; installing the tubular structure in the borehole, the annulus being formed between the tubular structure and the borehole; flowing a castable material into the annulus, the castable material partially displacing a fluid in the annulus, but leaving at least one space containing the fluid in the annulus; and expanding the expandable material into the space.

An annular packer device that is expandable in an annulus between an inner body and an outer boundary. The annular packer is sealingly movable along at least one of the inner body and the outer boundary. A method of sealing an annulus formed between a pipe and a borehole in a subterranean well can include positioning an annular packer sealingly around the pipe, expanding the packer into sealing engagement with the borehole, and permitting the pipe to displace relative to the packer while the packer remains sealingly engaged with the borehole.

Annular packer device

A method for setting a casing in a reduced diameter portion of a well bore whereby at least one annular packer may be positioned on an external surface of the casing and the packer may be conveyed into the reduced diameter portion of the well bore, thereby setting the casing. Cement can then be used to fill a region of an annulus formed between the external surface of the casing and the well bore above the packer. The packer may be preloaded, swellable, or expandable. The packer can be conveyed by applying a differential pressure to the packer, which longitudinally displaces the packer relative to the casing and forces the packer into the reduced diameter portion of the well bore.

Method and a device for setting a casing

A method and apparatus for perforating and isolating perforations in a wellbore. A perforating and isolating apparatus includes at least one packer having a swellable seal material, and a perforating assembly attached to the packer. A method of perforating and isolating perforations in a subterranean wellbore includes the steps of: positioning an apparatus in the wellbore, the apparatus including at least one packer having a swellable seal material, and a perforating assembly attached to the packer; isolating at least one existing perforation by swelling the seal material; and forming at least one new perforation by actuating the perforating assembly.

Method and apparatus for perforating and isolating perforations in a wellbore

A pipeline tool for use within a pipeline comprises a tool body with an internal flow bore, a swellable component disposed about the tool body, and a temporary seal disposed internally of the flow bore. The pipeline tool may further comprise a tracking device attached to the tool body, wherein the tracking device comprises a mechanical fixture, or an emitter that emits a signal that can be tracked.
