• Virtual RTU hardware

• Wireless field network


4


Spread-spectrum radios(RTU to remote I/O units) (RTU to multiple host computers)

Type #1 Type #2 Type #3


5


Remote I/O devices• Digital / analog inputs

• Pulse rate inputs

• Digital outputs

• RS-485 connector




6


Conventional RTU Typical I/O Capabilities• Digital / analog inputs

• Pulse rate / pulse counter inputs

• Digital to analog outputs

• Digital outputs

• RS-232 connectors


• USB connectors


7


Virtual RTU Expanded I/O Capabilities• Typical I/O capabilities of a conventional RTU plus additional:

• Digital / analog inputs

• Pulse rate inputs

• Digital outputs




8


• Wireless field network– Virtual field office

Advantages

• Reduce installation costs and improve safety by:– Minimizing or eliminating excavation and trenching around well sites

– Eliminating long-distance trenching and long U/G cable runs

– Eliminating installation of RTUs at wells with remote I/O units

• Enhance system reliability by:– Eliminating induced transient currents in long U/G cables

• Increase operations productivity by:– Providing field personnel with multiple access to the wireless network
