  • Publication number: 20230057971
    Abstract: A downhole pump gas eliminating seating nipple system for preventing and eliminating the collection of gas such as a foam barrier during operations of a downhole pump assembly. The downhole pump gas eliminating seating nipple system generally includes a seating nipple including an upper end, a lower end, and a channel extending between the upper and lower ends. The channel includes a beveled edge below the upper end and a locking lip above the lower end. A plurality of upper gas eliminators are positioned below the beveled edge including one or more elongate upper gas eliminators. A plurality of lower gas eliminators are positioned below the locking lip. Each of the gas eliminators is angled upwardly from inlet to outlet so as to prevent accumulation of gasses within or below the seating nipple, which can lead to gas locking and/or gas interference.
