The South Sumatra Basin is a predominantly onshore mature exploration province with a history of exploration dating back to the late 19th Century. It is the most active basin in Indonesia with more than twice the number of exploration wells from 2006 to 2015 than any other basin. Exploration is predominantly low risk and near field and as a result the average discovery over the last decade was just 7 mmboe. The majority of recent exploration has targeted oil and gas in Tertiary reservoirs and the play is expected to attract the majority of future investment. As infrastructure is abundant discoveries can be developed using relatively short tie backs to existing hubs and be brought onstream quickly sometimes within months. Indonesia's 2016 licensing round includes one block in the South Sumatra Basin as part of the Regular Tender the Batu Gajah Dua block. This report analyses costs volumes and economics.
