Australia's National Offshore Petroleum Titles Administrator (‘NOPTA’) has completed a project to gainmore detailed insights from field development and performance monitoring of Australian offshore gasdevelopments in Commonwealth waters (excluding state and Northern Territory coastal waters). Theseinsights help identify benchmarks for optimum long-term recovery and aspects of good oilfield practicewhen evaluating existing and future gas field developments. The methodology applied, high-level metrics,example analysis plots and key insights are discussed. A new confidential in-house Field Benchmarking Database (‘Database’) has been built, collating a largesubset of Australian offshore gas field data acquired by NOPTA from titleholders. The key datasets includefield and reservoir properties, facilities data, development timelines and development costs. The Databasealso references reserves information, production data and estimated ultimate recovery, thereby allowingfor quantified analysis and assessment of offshore gas fields in Commonwealth waters within a variety ofsubsurface, development, operational and commercial contexts. Data set correlations based on actual and planned long-term gas field performance, capital investment,and resource recovery are utilised to create a range of benchmarking plots focussed on production efficiency,recovery efficiency, schedule efficiency and cost efficiency. A number of key insights from these metricsare presented.
