A consortium of Premier Oil, Mubadala Petroleum and KrisEnergy has been awarded the Andaman II block, located in the offshore area of the North Sumatra Basin, on 31 January 2018. The block was offered as part of the Conventional Oil and Gas Bidding First Round 2017 under the Direct Offer mechanism. Premier Oil will operate the block with 40% interest while Mubadala and KrisEnergy will hold 30% participating interest each. The block will be operated under the new Gross Split fiscal terms. The base government/contractor split under Gross Split terms is 57%/43% for oil and 52%/48% for gas, subject to modifiers depending on the specific situation of the block. Signature bonus for the block was USD 1 million. The minimum exploration commitments for the first three-year exploration period include one G&G study and 1,850 sq km of 3D data including Pre-Stack Depth Migration (PSDM), shipborne gravity & magnetic data, for a total value of USD 7.55 million. The Andaman II block covers an area of approximately 7,400 sq km with water depth ranging from 250 m to 1250 m. Data available for this area consist of 9,310 km of 2D seismic data (ranging from year 1983 to 2008) and four wells. The block has been estimated by Migas to have prospective resources of 196 MMbo and 844 Bcfg. The offshore deepwater part of the area is relatively under-explored. One dry well, Bayu Laut Dalam 1, was drilled in this block by Inpex in 1994 under the North Aceh PSC. Several potential plays have been identified in this block, primarily targeting sandstones of the syn-rift stage (Parapat, Bampo formations) and post-rift stage (Peutu or equivalent, Baong and Keutapang formations). The main structural trends in the area are in N-S and NW-SE orientation. Directly south of the Andaman II block lies the Krueng Mane PSC, where the Jambu Aye Utara field is planned to be developed with first gas potentially in 2022. The Jambu Aye Utara 1 discovery successfully tested two sandstone zones within the Middle Miocene Baong Formation.
