DIAL units are the primary in-well control and monitoring component of Silverwell’s Digital Intelligent Artificial Lift production optimization system.
Each tubing deployed Concentric DIAL unit has up to six independently actuated gas lift injection valves. Custom orifice configurations are selected to match predicted gas injection needs across a well’s operating life.
Multiple DIAL Units can be installed with a single Tubing Encased Conductor (TEC) providing real time control of injection rate and depth. Integral Check Valves qualified to API 19G2 assure well integrity and are immune to chatter that plague conventional gas lift systems.
Continuous downhole permanent monitoring data informs production and reservoir management decisions including automated gas lift production optimization.
DIAL increases production and reduces cost with interventionless operation that dramatically reduces HSE risk. DIAL also enables deeper injection to maximize drawdown and efficient use of available lift gas.
Integrate in-well monitoring and lift gas injection adjustment for continuous and remote optimization without intervention.
Monitor and control lift gas produced from one zone to lift production from another.
