Historically, gas production to the Bacton gas terminal from the southern UK sector of the North Sea has been predominately lean gas. In the recent years fields producing richer gas have been added to the production system, bringing significantly increased condensate production. While the condensate is itself a valuable product, the increased volumes have raised a number of liquids management challenges both for offshore and onshore operations.
To address these challenges, a software-based operational guidance system has been deployed over a broadly integrated scope that includes onshore and offshore components. This system includes performance monitoring and operational guidance for the offshore compression stations, liquids and gas quality management for the offshore production system and operational guidance for the onshore plant. The implementation is well-aligned with SmartFields architectural approaches. This paper details the business case, the technical approach and the experience gained both in the implementation and operation of the system.
