This paper presents a novel design of a gas lift check valve featuring an integrated pressure isolation mechanism, aimed at optimizing gas lift operations in oil wells. Operators utilizing High Pressure Gas Lift, or Single Point Gas Lift systems are often converting to conventional gas lift or other Artificial Lift methods once the production has declined. However, this conversion requires a workover and a large capital impact to the operator. This new integrated pressure isolation mechanism offers operators the ability to convert from HPGL to conventional gas lift without the need of intervention.
The proposed gas lift check valve incorporates a unique pressure isolation mechanism within its design to address these challenges. This mechanism allows for controlled pressure release, preventing issues such as valve slamming, gas migration, and excessive backflow. The integration of this isolation feature enhances the valve's reliability and extends its operational lifespan, contributing to improved overall system performance.
The paper discusses the theoretical foundation, design considerations, and simulation results validating the effectiveness of the proposed BurstGuard device.
In conclusion, the integration of a pressure isolation mechanism within the gas lift check valve offers a promising solution to challenges encountered in converting gas lift systems, providing a more reliable and efficient method for optimizing oil well production. The innovative design presented herein has the potential to contribute significantly to the petroleum industry's efforts to enhance oil recovery processes while minimizing operational complexities and costs
