(2025048) ENHANCING PRODUCTION IN PERMIAN OIL WELLS USING ACID DIVERTER
Presenters: Erica Chalfant, SM Energy

As wells decline and available acreage for new wells lessens in the Permian Basin, it becomes increasingly important that operators capitalize on existing wells and maximize reserves. Scaling is a known issue in the basin, and this paper will address a likely solution. Acid treatments have proven to be effective across different levels, and when diverter is additionally pumped, the effectiveness has potential to increase significantly. 


The operator has taken the approach of pumping acid diverter jobs during workover when there is significant concern of blockages due to acid dissolvable scaling in the wellbore. Partnering up with an acid company, five acid diverter jobs have successfully been pumped across five different horizontals in Howard County, TX. These horizontals range across four different benches – Jo Mill, Lower Spraberry, Leonard, and Wolfcamp A. The Jo Mill well additionally had a cleanout across 84% of its lateral prior to pumping the acid diverter job, resulting this well yielding the highest oil uplift at 458% when comparing 30-day averages pre- and post-workover. The average of the other four jobs has oil uplift sitting at 189% with the same 30-day comparisons. Across the five jobs, four were during an ESP swap and one was during a RP workover. 


Other jobs pumped have insufficient days post return to production or faced significant curtailment post-workover, making it difficult to be considered in the study. Based on results thus far, the acid diverter program has been considered a success and candidates will continue to be added as seen necessary by respective production engineer.

(2026026) Addressing Gas Lift Challenges With Innovative surface-Controlled Technology
Presenters: Andrew Poerschke, SLB

Oil and gas operators increasingly face difficulties optimizing production from wells characterized by variable flow regimes and dynamic pressure conditions. Conventional gas lift systems are often unable to respond effectively to these fluctuations, resulting in inefficiencies, elevated downtime, and reduced hydrocarbon recovery. These challenges are compounded by the need to control costs, particularly in marginal or complex well environments.
 
A newly developed surface-controlled gas lift technology addresses these limitations by enabling dynamic, precise adjustment of gas lift performance. The system integrates coordinated surface and downhole components to allow real-time modification of valve setpoints in response to changing well conditions. Using a hydraulically actuated mechanism, the technology provides accurate valve control independent of injection pressure, minimizing pressure losses and enhancing production rates.
 
Constructed with robust, industry-standard materials, the system is designed for reliability and seamless integration with existing infrastructure. Its ability to continuously optimize valve setpoints allows operators to "shoot the gaps" across a broad range of flow rates and pressures. Additional capabilities such as reversing injection flow or over-pressuring valves to clear obstructions further improve operability and reduce downtime.
 
Field deployments have validated the systems performance in annular, conventional, intermittent, and high-pressure gas lift applications. Demonstrating more than 8,500 open/close cycles over a one-year period, the technology offers durable, cost-effective production enhancement and reduced operating expenses.
 
By resolving the fundamental constraints of traditional gas lift designs, the surface-controlled system provides improved efficiency, operational flexibility, real-time visibility, and consistent repeatability under a wide range of well conditions.
