The field produced first oil in April, initially from four pre-drilled wells. Since then another seven wells have been completed and put onstream, lifting output to the plateau rate of around 14,000 boe/d.
Results from all the wells indicate that the field’s western part is structurally deeper than originally modeled while the eastern side is structurally higher than first thought. This has led to changes in the drilling sequence/targets of the later development wells.
Last month the partners drilled the Bertam-3 appraisal well which confirmed additional resources in the northeastern part of the field. A long-reach horizontal development well will be drilled from the Bertam wellhead platform early in 2016 and put into production immediately after completion.
Recently, Lundin took on JX Nippon’s 40% interest in block PM308A, lifting its equity to 75%. The company and partner Petronas Carigali have decided to drill the Selada prospect PM307/PM308A, and have fully aligned their stakes in the two licenses.
Drilling of Selada will start after Bertam-3 has been completed. The prospect is 15 km (9.3 mi) south of the Bertam infrastructure and a commercial discovery could be tied back to the FPSO.
Offshore Sabah, Lundin has completed the high-grading of its prospect inventory for the SB307/SB308 concessions based on existing 3D seismic, and with Petronas plans to drill two exploration wells early in 2016 on the Imbok and Bambazon prospects.
Both are on trend with Shell’s producing oil fields St Joseph, Barton, and South Furious. Imbok could potentially hold 53 MMboe and Bambazon 56 MMboe.
In July, Lundin acquired EnQuest’s 42.5% stake in both concessions, increasing its interest to 85%.
