A side pocket mandrel is configured for use within a gas lift system deployed in a well that has an annular space surrounding the gas lift system. The side pocket mandrel includes a central body that includes a central bore, a gas lift valve pocket, and a gas lift valve installed within the gas lift valve pocket. The side pocket mandrel may also include a motorized choke valve assembly to selectively cover some or all of an internal tubing port extending between the central bore and the gas lift valve pocket. The side pocket mandrel may also include an automatic closing valve assembly configured to automatically close the gas lift valve port when the gas lift valve is removed from the side pocket mandrel.

A hydraulic landing nipple assembly includes a control line port located at an outer surface of a tubular member having a bore therethrough, an upper seal recess positioned above the control line port, and a lower seal recess positioned below the control line port. The upper seal recess and the lower seal recess each define locations within the bore to receive an upper locking mandrel and a lower locking mandrel of a subsurface safety valve.

A latch design for downhole components is provided. The latch design includes a dog assembly instead of a traditional shear pin design to allow the latch to withstand greater forces and more cycles than the traditional design.

Systems and methods include a plug activated mechanical isolation device that controls fluid flow inside a tubular in a wellbore. The device includes a sleeve for coupling to the tubular, and the sleeve includes an internal bore and port for fluid flow therethrough. A channel element is positioned in the internal bore and includes an internal channel and an orifice for fluid flow between the internal channel and internal bore. The channel element is attached to the sleeve via a breakable attachment portion, and the orifice is aligned with at least one port of the sleeve. The channel element is slidable within the sleeve, upon breakage of the breakable attachment portion with a force, to move the orifice out of alignment with the port of the sleeve so that a portion of the channel element covers the port of the sleeve to block fluid flow through the port.

A lock mandrel is described herein. The lock mandrel includes an upper connector and a lower connector. The upper connector includes locking keys configured to attach the lock mandrel to a landing nipple on a tubing within a hydrocarbon well. The upper connector also includes a spring-loaded locking collar configured to prevent the locking keys from disengaging from the landing nipple by pressing radially against the locking keys from the inside when in a seated position, and allow the locking keys to disengage from the landing nipple by retracting away from the locking keys when in an unseated position. The lower connector includes a tool adaptor configured to attach a downhole tool to the lock mandrel.

An assist device for propelling a tool through a conduit, the assist device including an upstream housing having a first port; a downstream housing movably attached to the upstream housing and the downstream housing having a second port; and a swab element attached to the downstream housing. The first port is closed when there is no gap between the upstream housing and the downstream housing, and the first port is open when there is a gap between the upstream housing and the downstream housing.

One downhole-type tool of a set of interchangeable downhole-type tools is interchangeably received by a pump-down adapter. The downhole-type tool is positioned by the pump-down adapter within a wellbore tubular. The downhole-type tool is released by the pump-down adapter.
