摘要： An electric bonnet includes a housing; a guide piston disposed in the housing; an electric motor having a motor shaft; a rear housing connected to the housing; a gearbox assembly disposed in the rear housing, the gearbox assembly being coupled to the motor shaft of the electric motor; and a roller screw assembly disposed in the rear housing. A first end of the roller screw assembly is connected to the gearbox assembly, and a second end of the roller screw assembly is connected to the guide piston. Rotation of the motor shaft of the electric motor transmits rotary motion to the gearbox assembly, which transforms the rotary motion into linear motion using the roller screw assembly. The linear motion of the roller screw assembly actuates the guide piston.

摘要： A technique facilitates intervention operations in many types of wells including horizontal, multi-zone wells. According to an embodiment, a completion is deployed in a borehole, e.g. a deviated wellbore. The completion comprises a side pocket mandrel having a docking station. In some embodiments, the completion may comprise a plurality of the side pocket mandrels A device, such as an electrically powered device, is removably deployed in the docking station. When the docking station receives the electrically powered device, an inductive coupler or other suitable electric coupler may be used to provide power to the electrically powered device while deployed in the docking station. The electrically powered device also is configured for engagement with a tool which enables an intervention operation by simply removing and replacing the device via the tool.
