Wellhead Junction Box
Used for electrical power surface connections
Vent gas from downhole cables so it does not reach the variable speed drives.
The Schlumberger site communication box (SCB3) provides simple, flexible, and secure access to real-time data from remote wellsites located almost anywhere in the world while enabling automation and data buffering to overcome most communication outages without data loss. The SCB3 uses the high-speed BGAN satellite network to enable remote data communication throughout most of the world.
The network transmits data to Schlumberger servers, allowing web-based viewing or data extraction as required. Around-the-clock support, integrated with other Schlumberger network activities, is also available.
The SCB3 is installed and commissioned in hours by regular field crew, and the hardware is preconfigured for standard Schlumberger acquisition and control systems. Removable, clearly labeled connector plugs speed installation and wiring. Schlumberger wellsite systems can also be customized to integrate additional third-party equipment and sensors that can be critical for complete system monitoring and analysis.
The common Modbus RTU protocol for data acquisition fully supports RS-232 and RS-485 (2-wire and 4-wire) interfaces for device connection.
