Key Sources of Oil Supply
Crude oil
Indonesia ( Sumatran Light : Minas, Cinta, Widuri etc. ), Australia ( Wandoo, Stag ),
Vietnam, etc.
Low sulfur content ( 0.1 – 0.15 % ) required to meet strict environmental regulations.
Consequently, Southeast Asian and Australian crude oils as key sources.
Fuel oil
Mainly domestic product refined at Japanese refinery.
LSFO and LSWR imported as complementary from Indonesia and Singapore etc.
Key specification is low sulfur content.
Domestic product : 0.1 – 0.3 %, Imported LSWR : 0.2 – 0.3%
