Prima Energy Northwest Natuna Pte. Ltd. (PENN) and Satuan Kerja Khusus Pelaksana Kegiatan Usaha Hulu Minyak dan Gas Bumi (SKK Migas) have revised the plan of development (PoD I) for Ande-Ande Lumut (AAL) oil field in the West Natuna Sea, 20 km from the Malaysian border and about 260 km from shore.
The project will be implemented in two phases. Production scenarios involve use of a central production platform (CPP) and floating, storage, and offloading (FSO) unit, representing a change from the previous concept which called for a well head platform (WHP) and floating, production, storage, and offloading (FPSO) vessel.
Initial development work includes installation of platform jackets and drilling of seven horizontal production wells to produce oil from both K and G sand layers. Unconsolidated sand reservoirs and heavy oil require long horizontal well drilling and specialized lower completion wells to limit water and sand production, the comapnies said.
The revised PoD I has been approved by the Ministry of Energy and Mineral Resources (ESDM). The production target for end-2026 is 20,000 bo/d.
AAL lies within the 461-sq km single block Northwest Natuna PSC next to the Malaysian border in less than 70 m water depth. Reservoir depth is about 1,100 m.
PENN is operator at AAL (50%) with partner Prima Energy AAL Singapore (50%). SKK Migas was established by the Indonesian government to oversee upstream oil and gas activities in Indonesia.
