A downhole tool conveyable on a coiled tubing string. The downhole tool has: an electric actuator; one or more sensors; and a control unit adapted to receive and interpret data from the one or more sensors, wherein the control unit is adapted to operate the electric actuator in a closed-loop configuration based on data received from one or more of the sensors. A method of operating such a downhole tool.

Downhole tool and method for operating the same

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.
