US Patent 11851961 Magnetically coupled subsurface choke

Provided is a retrievable choke insert. The retrievable choke insert, in one aspect, includes an outer housing including a central bore extending axially through the outer housing, an open end, a closed end, and one or more outer housing openings extending through an outer housing sidewall thickness, and a bore flow management actuator disposed in the central bore, the bore flow management actuator having one or more bore flow management openings extending through a bore flow management actuator sidewall thickness, the bore flow management actuator operable to convey subsurface production fluids there through. The retrievable choke insert, in accordance with this aspect, further includes one or more choke insert magnets coupled to the bore flow management actuator, the one or more choke insert magnets configured to magnetically couple with one or more landing nipple magnets of a choke landing nipple to slide the bore flow management actuator and move the one or more bore flow management openings relative to the one or more outer housing openings to control an amount of the subsurface production fluid entering the bore flow management actuator.
