Concentric DIAL Units

Higher rate single string wells & in-situ gas lift

Concentric DIAL Unit

DIAL units are the primary in-well control and monitoring component of Silverwell’s Digital Intelligent Artificial Lift production optimization system.


  1. Onshore & offshore higher rate single string wells

    Integrate in-well monitoring and lift gas injection adjustment for continuous and remote optimization without intervention.

  2. In-situ auto gas-lift applications

    Monitor and control lift gas produced from one zone to lift production from another.


  1. Surface controlled variable orifice size

  2. Integrated back-pressure valves

  3. Tubing & annulus pressure and temperature sensors

  4. No gas-charged bellows

  5. Unlike conventional valves, no casing pressure loss when transferring stations

  6. Testable cableheads and E-Beam welded construction

  7. Interventionless and remote operation

  8. Low power draw

  9. Onboard condition monitoring


  1. Continuous production optimization without intervention

  2. Qualified to industry standards to maintain well integrity

  3. Real-time visualization of flowing gradient and in-well lift gas injection rate to assess well performance for date-driven decisions

  4. Consistent valve performance, regardless of well conditions, and eliminates chatter or multi-consistent continuity and comms testing to identify TEC Damage pointing

  5. More efficient use of available lift gas to inject deeper and/or lift more wells with the same available compression horsepower and less injection stations

  6. Hermetically sealed electronics enables life-of-well reliability

  7. Continuous production optimization with reduced logistics costs less HSE risk exposure

  8. Solar powered operation in remote environments

  9. Feedback of correct valve actuation and overall system health

Case Histories

Operators around the world are continuously optimizing gas lifted production with DIAL wells configured for single string, dual string or in-situ production.
