Important new safety and operational features and some industry firsts are employed in a PC-based supervisory control and data acquisition (scada) system at Phillips Petroleum Resources Ltd.'s Ghost River sour-gas field and pipeline in a populated area near Calgary. This paper reports on the scada system monitors and controls wells, line-heaters, pumps, and alarm and shutdown systems. facilities are operated on a partially attended basis. Operators carry cellular telephones and laptop computers equipped with internal modems to enable them to receive alarms and take appropriate action promptly. Several safety features are incorporated into the alarm and shutdown system. All aboveground facilities are equipped with atmospheric monitors for H{sub 2}S. Leak detection is inferred from continuous material-balance computation. Should a sour-gas leak be suspected, an automated resident-notification system provides early notice by telephone to potentially affected residents.
