Benefit From Enhanced Control with the Adaptive Gas Lift System
The Adaptive Gas Lift System (AGLS) is the world’s first retrievable electric gas lift system, designed to help operators accelerate and maximize oil production. It enables operators to remotely control and adjust choke opening of the gas lift valves, without the need for costly well interventions. Built on field-proven downhole technologies from Emerson and Interwell, it delivers a robust and reliable solution for enhanced production performance.
Key Benefits
Gas lift is a widely adopted artificial lift method. The Advanced Gas Lift System provides enhanced control, without the need for manual intervention. With a unique, low power electrically actuated gas lift valve, operators can remotely optimize choke openings and in turn optimize gas injection rates and depths easily and effectively.
With the control the Advanced Gas Lift System provides, operators can efficiently adjust to maximize production. For example, as well conditions change, there could be a need to transition to a deeper injection point. The flexibility of the AGLS allows operators to adapt remotely to retain enhanced production rates for as long as possible and ultimately ensuring increased total reservoir drainage.
Traditional gas lift systems have limited adaptability, and changes require expensive manual intervention. Even still, only one configuration is achieved until the next shut-in intervention takes place. The AGLS enables remote, dynamic changes to be made as often as required, to ensure an optimized arrangement. This reduces the need for expensive downtime and manual activities significantly.
The AGLS utilizes field-proven technology, qualified to the highest industry standards. The Roxar Downhole portfolio from Emerson and the valves from Interwell are known for robust, reliable performance, providing assurances for operators as they select their downhole monitoring and control approach. As an extra safety precaution, should a failure occur, the solution is easily retrievable and replaceable.
With AGLS, operators can remotely control valves for optimal gas injection rate and depth, ensuring improved use of available gas, reduced CO2 per barrel, as well as production optimization and ultimately increased total reservoir drainage. The need for extensive work-over operations is removed, avoiding the associated carbon footprint, supporting the journey towards net-zero energy production.

How It Works
The Integrated Downhole Network (IDN) is the Roxar system architecture from Emerson. Operators connect to the Downhole Network Controller with Ethernet, RS422 or RS485 and from there a single cable is run downhole. This cable can support up to 32 Roxar downhole instruments, including of course the AGLS.
The side pocket mandrel serves as a receptacle for the Adaptive Gas Lift Valve (AGLV). It allows for the installation and retrieval of the AGLV, without the need to pull the entire tubing string. Interwell has a robust and reliable, field-proven design, which withstands extreme downhole conditions, ensuring long term performance and minimal maintenance requirements.
The Adaptive Gas Lift Valve (AGLV) is the combination of Interwell’s field-proven valve design and Emerson’s communication and power infrastructure. An inductive coupler and an actuator enable a unique, low power, adaptive valve solution, resulting in the operator benefiting from the world’s first retrievable electric gas lift system, providing a new level of control and reliability.
