How can we achieve high rates reliably and at a lower cost? The answer, increasingly, is High-Pressure Gas Lift (HPGL).
Since its introduction in the field, HPGL has emerged as a formidable alternative to traditional artificial lift systems, particularly Electric Submersible Pumps (ESPs). As a still-emerging technology, documented field results are continuing to be developed. So far, the insights from 3,500+ installations in the last seven years, combined with extensive data from five newly studied wells, are poised to change the way the industry views HPGL.
Back in 2017, the question was raised: Can HPGL offer a viable, cost-effective solution for producing high rates from unconventional wells? By 2019, the answer was a resounding yes, with HPGL demonstrating performance rates comparable to ESPs (SPE 195180). However, the true breakthrough lies in HPGL's simplicity, reduced failure rates, and lower operational downtime—making it a more economical choice for operators.
The latest field data reinforces this point. Wells equipped with HPGL have consistently delivered high production rates without the complexity and maintenance challenges of ESPs. The ability to produce comparable rates, coupled with fewer failures and simplified operations, presents a powerful economic case for adopting HPGL over ESPs.
One of HPGL’s standout advantages is its flexibility and simplicity in design. The well tubulars are readily modeled to predict and optimize rates, and facilities can be designed to support maximum flow rates while mitigating slugging—a common issue with other artificial lift systems. This capability gives operators the control they need to optimize production without the need for extensive reconfigurations or costly downtime.
Further, HPGL wells are easy to adjust and optimize in real-time. Operators can make changes to injection rates while closely monitoring surface pressures, ensuring peak performance with minimal intervention. This adaptability provides a significant edge in maintaining well profitability.
Another critical finding from the extensive HPGL operations data is the substantial benefit of electric units where reliable line power is available. While gas units have their place, electric units offer lower emissions, smoother operations, and often greater efficiency when power infrastructure supports their use. For operators with access to good line power, the switch to electric units can represent a significant operational advantage.
The key takeaway from this comprehensive study is that HPGL not only delivers on performance but does so with significantly fewer headaches for operators. The simplicity of its design and operation, along with the adaptability it offers in managing production rates, makes HPGL a standout choice for wells in a range of conditions.
Moreover, HPGL’s economics are compelling. Compared to ESPs, HPGL systems come with lower operational costs, reduced downtime, and fewer failures—translating to increased profitability for operators. When factoring in both production rates and lifecycle costs, HPGL has established itself as a superior artificial lift option for many unconventional wells.
With its proven success, HPGL continues to be adapted across the industry. As more data is shared amongst thousands of installations coupled with five detailed case studies – the industry’s understanding of this evolving artificial lift technology will only accelerate and drive increased adoption. The learnings from current five case studies and future applications will provide operators with critical insights they need to evaluate and apply HPGL more effectively in the future.
By bringing the operational data and economic benefits of HPGL into focus, Flowco is helping operators make informed decisions about the best artificial lift method for their wells. High-Pressure Gas Lift is no longer just an alternative—it’s a proven solution for those seeking to produce high rates reliably and economically.
