This paper analyses a range of load distribution patterns between process trains of upstream gas treatment units fitted with process control systems operated across oil and gas fields in Russias Far North regions. The authors specifically consider fuzzy logic-based train control schemes introduced into existing control systems. System inputs include equipment status and quality of feedstock gas under treatment, while generating expert adjustments to capacity of individual system parts. Load distribution system knowledge base was built around various logical/linguistic models absorbing fuzzy logic elements. This enabled us to identify gas equipment and quality impacts on drying performance. The system was successfully tested at Yamburg field Kharvutin area.
