At Alaska’s North Slope, existing fields span a large geographic area where three phase production fluids can cause severe corrosion. To monitor corrosion and provide feedback for the chemical mitigation program, electrical resistance probes connected to remote data collectors are installed at approximately 80 locations. Measurements are made on a four hour interval at each location, and data are collected during weekly site visits. A wireless remote monitoring unit utilizing a mesh network of 900 MHz spread spectrum radios was developed to collect data from the existing hardware and transmit it to a central location. In a pilot project, five remote monitoring units and one central unit were successfully deployed in the summer of 2005.
