The Baram Delta Basin is located off the north coast of Borneo and straddles the maritime boundaries of Malaysia and Brunei. Historically, exploration activity focused on onshore and shelf prospects, but these plays are now largely drilled out. Explorers are now targeting deep (primarily HP/HT) gas on the shelf; and the oil potential of the relatively under-explored Tertiary deepwater play. Since 2008, explorers have added significant volumes, with the average find exceeding 57 mmboe, higher than the regional average. Despite achieving above average overall success rates for much of the decade, explorers have faced significant challenges commercialising their finds. Many of the outer deepwater finds hold sub-economic volumes, and a lack of capacity in gas infrastructure means that operators struggle to sell gas to the export market. Access to prospective acreage is also an issue. Full details are available for download in pdf and xls format.
