  • Patent number: 11661827
    Abstract: A process for aging gas lift valves utilizing a controlled decompression to prevent damage to seals of the gas lift valves. The process includes pressuring one or more gas lift valves to a predetermined pressure (e.g., 5000 psig) and maintaining this pressure for a predetermined time (e.g. five minutes). After this time period, decompression is performed in discrete steps. For instance, the pressure of the pressure vessel may be reduced in predetermined pressure increments (i.e. reductions). After each pressure reduction, the reduced pressure is maintained for a predetermined time. This allows gasses and fluids within the elastomeric O-rings time to dissipate without causing damage to the seals.

  • Patent number: 11629710
    Abstract: A plunger having a generally hollow interior between an open upper end of the plunger and a closed bottom end of the plunger. One or more orifices extend through a sidewall of the plunger near the closed bottom surface. The orifices fluidly connect the hollow interior of the plunger with the tubing below the plunger when the plunger is in use. The orifices allow for a transfer of gas from the well bottom into the liquid load above the plunger during plunger ascent. The orifices also allow liquids to pass through the plunger during plunger descent.
