A tool and a method are for at least one of gripping, expanding, and penetrating a wall of a bore. The tool has a first tool part and a second tool part arranged axially movable relative to each other. The first tool part has a solid wedge, whereas the second tool part has at least one wedge arm. The first tool part further has at least one influencing portion configured to be radially movable upon contact with the at least one wedge arm of the second tool part. The at least one wedge arm is configured to be moved axially along the solid wedge so as to be forced radially outwards and thus push the at least one influencing portion radially outwards.

Tool and a method for at least one of gripping, expanding, and penetrating a wall of a bore

This invention relates to a sealing apparatus, system and method for use in a well pipe. The apparatus has a mandrel arranged around a center axis through the apparatus, a radially movable gripping device arranged around the mandrel, a radially movable packer element arranged around the mandrel, and an axially movable activation device designed to set up axial forces for activating the apparatus. The apparatus also includes a radially movable centralizer arranged around the mandrel for centring the apparatus. The activation device being operatively connected to the gripping device, the packer element and the centralizer for the respective activation and radial movement of each, via power transmission of axial forces, between retracted, passive positions and expanded, active positions relative to the center axis of the apparatus.

Apparatus for sealing a bore, a system comprising the apparatus and a method for using apparatus

A downhole actuator device comprises a central shaft formed with external threads; a sleeve formed with internal threads and placed substantially concentrically around the shaft; and an electromotor arranged to rotate at least a first one of said shaft and said sleeve so that a second one of said shaft and said sleeve may be moved linearly relative to the first one of said shaft and said sleeve. The actuator further comprises a plurality of roller screws that are rotatingly supported between the shall and sleeve in engagement with said external threads on the shaft and said internal threads on the sleeve.

Downhole actuator device

A downhole tool is arranged for connection to a fluid-carrying string. The downhole tool includes: a first reversibly expandable sealing element; a second reversibly expandable sealing element placed at an axial distance from the first reversibly expandable sealing element; one or more fluid ports positioned between the two reversibly expandable sealing elements and arranged to be put in fluid communication with the fluid-carrying string; a first anchoring device arranged to engage a pipe body in a well; and one or more electromotors arranged at least to operate the two reversibly expandable sealing elements and the first anchoring device. The downhole tool further includes a first mechanically activatable release mechanism arranged at least to disengage the first anchoring device from the pipe body. A method is for utilizing a downhole tool.
