Abstract

In general, most offshore platforms are designed for 20 to 30 years of lifespan. After the field completed its maximum production plateau for a certain period, the reservoir pressure started to deplete, resulting in a decline in production rate until it is uneconomical to produce from the field. This declined production phase is referred to as Mature Offshore Fields/Assets. Almost 90% of offshore platforms in Peninsular Malaysia Assets operated by Petronas Carigali Sdn Bhd (PCSB) are within this phase. The study objective is to establish an analysis tool by consolidating the data from various system resources into a single presentation to provide the status of mature field performance, visualize the area that requires improvement, and subsequently identify performance improvement recommendations. The study will also focus on identifying which data and the resources needed to be extracted and the standards mentioned in guidelines available in the company to be used as a benchmark or comparison. This data compilation is interpreted into a Microsoft Excel spreadsheet and charts. As the study focuses on mature field operations, the three elements been identified as study subjects, i.e. plant utilization as production declining, operating cost and unplanned trips or shutdown. From the data simulation sample, the performance of Field A can be summarized and visualized clearly, and the area of improvement required can be identified with value creation being estimated.
