DIAL is a production optimization system integrating in-well monitoring and control of gas lift well performance, with surface analytics and automation, to continually optimize gas lifted fields remotely and without intervention.

DIAL System

The DIAL system brings data and control integration to gas lift production management. A Surface Control System (SCS) allows local or remote monitoring of in-well production parameters of pressure, temperature, and injection rate. The SCS also controls in-well DIAL gas injection units to vary gas injection depth and rate, without intervention, to maintain optimized production.

DIAL units are the in-well component of the system and each one features up to 6 independent injection orifices with a different port size, offering a wide range of possible injection rates. The injection orifices can be individually opened and closed from the surface without requiring a drop in casing pressure, offering deeper injection and increased production. DIAL units are connected to surface via a tubing encapsulated conductor (TEC) that provides power and communications.

When combined with Silverwell’s Digital Integration Unit (DIU) and associated DIAL-It-In software suite gas lifted well production optimization can be fully automated. Aligning with the widening adoption of digital oilfield production management strategies DIAL systems automate several processes such as well unloading, production optimization, gas usage optimization, and troubleshooting can be automated under the supervision of the operator.
