Slimline DIAL Units

Dual-string gas lift & smaller diameter casing

Slimline DIAL Units

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


  1. Dual-string wells

    Integrate in-well monitoring and lift gas injection adjustment to optimize both producing zones without intervention.

  2. Smaller diameter casing

    Slimline configuration for interventionless gas lift optimization of single string completions in smaller casing sizes.


  1. Slimline eccentric design for dual string completion

  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. Independent control of gas lift to both producing zones

  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-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.
