An integrated milling and production device. The device includes a production housing, a connector, a motor, and a milling bit. The production housing has a central bore with at least one flapper valve pivotally disposed therein and an actuator. Upon completion of milling operations, the connector may be disengaged from the production housing. The production housing may be repositioned in the well. Activation of the actuator permanently opens the flapper valve to permit the flow of production up the production housing to the well surface. The actuator may be a piston.

Integrated milling and production device

A mechanically locking hydraulic jar device includes an outer sleeve, an inner sleeve partially disposed in an inner bore of the outer sleeve, and a mechanical lock engaging the outer sleeve and the inner sleeve in a default position to axially secure the inner sleeve to the outer sleeve. Activation of the hydraulic jar disables the mechanical lock to allow axial movement of the inner sleeve relative to the outer sleeve, which generates an impact force when the inner sleeve reaches an activated position. The hydraulic jar device also includes an upward block and a downward block configured to limit the upward and downward axial movement, respectively, of the inner sleeve relative to the outer sleeve when the mechanical lock is disabled.

A vibration assembly includes a valve above a rotor and stator. The rotor rotates within the stator as fluid flows therethrough. The valve includes a rotating valve segment, which rotates with the rotor, and a non-rotating valve segment each including at least one fluid passage. In an open position, the fluid passages of the valve segments are aligned and a fluid flows through the valve. In a restricted position, the fluid passages of the valve segments are partially or completely unaligned, thereby creating a pressure pulse that is transmitted through the drill string or coiled tubing above the valve. The valve may further include an inner sleeve and an outer sleeve surrounding the non-rotating valve segment. The inner and outer sleeves allow axial sliding but prevent rotation of the non-rotating valve segment. The assembly may further include a lower thrust bearing at a lower end of the rotor.
