A supervisory control and data gathering system has been installed in theNorth Pembina Cardium Unit No. 1, which is operated by Socony Mobil Oil ofCanada, Ltd. This system provides, at one central location, read-out ofproduction data, logging of alarm conditions and supervisory control overthirty-five satellite production stations and two central treating stations,handling a total of 462 producing wells. The production data reported includewell-test oil, water and gas volumes. The supervisory control system providesremote control of all production wells. This system was designed making use ofessentially conventional electrical components. It has been in successfuloperation for more than eighteen months, effecting reduced maintenance andoperating costs while providing increased speed and accuracy in the gatheringand processing of production data.
In the North Pembina Cardium Unit No.1, a total of 462 wells produce intothirty-five satellite well testing units. The production from the satelliteunits is moved through a pipeline gathering system and is processed at twotreating plants. A map showing the production system field layout isgiven inFigure 1. The design of this production system has been described inprevious publications (1, 2).
The satellite units provide individual well production test measurements ofoil, water and gas volumes, and regulate and monitor oil production andtesting. The treating plants accept crude-water emulsions from the satelliteunits, dehydrate and ship the oil, and treat and dispose of the water. Gas isseparated and sold from the satellite units and the treating plants.
This production system requires that considerable measurement and operatingstatus information be acquired from the satellites and the plants which aredistributed over an area of roughly 70 square miles. In addition, certaincontrol functions must be effected at these locations. For the purpose of bothgathering the information and effecting the needed control, a centralized datagathering and supervisory control system is provided. This system has been inoperation for 18 months and is highly successful.
