The South Sumatra Basin is a predominantly onshore, mature exploration province, with a long history of exploration. Over 3.7 bnboe of resource has been discovered. It is the most active basin in Indonesia, with more than twice the number of exploration wells over the last decade 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 6 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 2018 licensing round includes two conventional blocks in the South Sumatra Basin: Southeast Jambi (under direct proposal), and Air Komering (under regular tender).
