Summary
The SCS Surface Control System (SCS) is the well-site interface component of Silverwell’s DIAL production optimization system.
Via a Tubing Encased Conductor (TEC), the SCS operates in-well DIAL Units to continuously monitor downhole conditions and control gas injection rate and depth. The SCS controls the system at the wellsite with push-button controls and touch-screen, or remotely via the operator’s DCS and SCADA systems. Production engineers can review in-well data and adjust gas injection rate and depth on site or remotely.
Easily integrated into existing DCS and SCADA systems, DIAL’s SCS has a small footprint, low power requirement and data logging, enabling operation in remote areas. It is highly customizable including Ex rating and multi-well installation.
Applications
-
Interior or exterior installation
connected to in-well DIAL system and configurable for single or multi-well applications.
-
Configurable
Onshore or offshore, Zone or Ex rated, optional solar power, tolerant of desert and arctic remote environments.
Features
- Remote monitoring and control of DIAL units with available automation
- Low power requirements and small footprint
- MODBUS communications protocol
- Customizable
- Multiple DIAL unit capability
- Local and remote control and monitoring of DIAL units
- Data-logging
- Intuitive and user-friendly navigation

Benefits
- Continuous well optimization, with associated production increase, without cost and risk of intervention
- Ease of installation including solar power capability in remote locations
- Industry standard for ease of integration into existing control systems
- Explosion proof ratings, multi-well or string completions and severe environments
- Each SCS can control up to 16 DIAL lift gas injection and sensing units
- Touch-screen display for data-driven production management decision making
- SCS stores data locally for troubleshooting, data recovery, and operation with non-SCADA installations
- Encourages users to adopt a more interactive and immediate approach to gas lift well optimization and troubleshooting
- Assures system up-time and reduced non-productive time
