The Schlumberger site communication box (SCB) can provide simple, cost-effective, low-maintenance access to real-time data from anywhere in the world.
The SCB includes a power supply, a processor-assisted connector (PAC) to collect/buffer data, and a satellite modem to transmit through wide area wireless service (WAW) via satellite.
Global version
The global version of the SCB can be configured for AC power (SCB-BA) or solar power (SCB-BB).
An SCB-BA is fully assembled with a modem, a PAC, a power supply with battery backup, and wiring inside a protective enclosure. The assembly includes a common ground bus bar for grounding to a single point. All wiring and terminals are labeled and a full set of electrical drawings is included.
Most common input/output (I/O) points are voltage, current, temperature, pressure, flow, and vibration from both surface and downhole sensors. Other I/O types are possible.
The hardware is preconfigured for standard Schlumberger acquisition and control systems. Schlumberger wellsite systems can also be customized to integrate additional third party sensors, which can be critical for complete system monitoring and analysis.
The SCB-B is for use in all areas of the world except North America. The SCB-A is used for operation in North America. An SCB is available for 115/230 V AC (SCB-BA) or solar power operation (SCB-BB). In the event of a power outage, battery backup will provide power for one day of operation.
