Natuna Sea Block A PSC ("NSBA")


  • KUFPEC (33.33%), PMO (28.67%*), Petronas (15%), Pertamina (11.5%), PTTEP (11.5%)
    • Pertamina and PTTEP acquired their stakes as part of Hess' Indonesian portfolio
  • NSBA supplies gas to SembGas in Singapore, together with South Natuna Sea Block B and Kakap, as part of a GSA signed in 1999 for a period of 22 years
    • In 2008, PMO signed two additional GSAs to supply NSBA gas for power generation in Batam, Indonesia
    • Due to delay in constructing the pipeline to Batam, a swap agreement has been signed for the Batam earmarked gas to be supplied to Singapore and another field to supply Batam instead
  • The largest field on the block is Anoa which contains about half of the PSC's gas reserves. Gas from Anoa, Pelikan, Bison and Gajah Puteri are dedicated to the SembGas 1 GSA
  • SembGas 2 is predominantly supplied by Gajah Baru which was developed as a second phase of NSBA
  • Crude is piped by an 8" pipeline to the Anoa Natuna FPSO for processing and storage
  • Gas is exported via the West Natuna Transportation System (operated by COP) and serves the three Natuna PSCs (NSBA, South Natuna Block B and Kakap)
    • The network consists of 656km of pipeline, with a 470km section transporting the gas to Singapore
    • A pipeline connecting the system to Batam is also planned but is the responsibility of the buyers of the gas
    • The pipeline costs are recoverable under the PSCs
