Abstract: An apparatus may include a production riser (1), an eductor (2), a motive fluid line (3), a suction line (4), and a mixed fluid line (5). The production riser may extend into a wellbore and be configured to convey production fluid from the wellbore to a wellhead (7). The eductor (2) may be configured to mix a slip stream (9) of the production fluid (6) with high-pressure motive fluid (12), providing a mixed fluid (9). The motive fluid line may extend into the wellbore from a compressor to the eductor and be configured to provide the high-pressure motive fluid to the eductor. The suction line may be configured to provide the slip stream from the production riser to the eductor. The mixed fluid line may be configured to convey the mixed fluid from the eductor to the production riser. A method and system may employ such an apparatus.

Abstract: A dummy valve comprising a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber and associated systems and methods.

Abstract: A gas lift barrier valve mandrel assembly includes a longitudinally extending tubular member that defines a production conduit and has a central longitudinal axis. A side pocket mandrel has a first pocket for accepting a gas lift barrier valve and has a first central axis. The side pocket mandrel has a second pocket for accepting a gas lift barrier valve and has a second central axis. The central axis of the production conduit, first axis and second axis are non-coaxial and are parallel to one another. A passage fluidly connects an outside of the mandrel to an inside of the production conduit and is intersected by the first and second pockets.

A third passage fluidly connects the inside of the second pocket to the production conduit. A fourth passage connects the first pocket to the production conduit and allows insertion of a gas lift barrier into the first pocket.
