RESERVES:Initial Oil: 107.2 MMbblsRemaining Oil: 5.3 MMbbls (at end 2001)Source: Northern Territory Depatment of Business Industry and ResourceDevelopment, 2002.REMARKS:Fluid inclusion studies by O’Brien & others (1996) have identified a residual oil zone below the presentday OWC. This suggests that the Jabiru structure originally contained considerably more oil than it holdsat present and that this oil has subsequently been leaked as a result of Mio-Pliocene fault reactivation.Commercial production of oil from Jabiru commenced in 1986. The development at Jabiru comprisessub-sea completions connected via flowlines to an FPSO vessel (the Jabiru Venture).At date of publication, the Jabiru oil field was held under Production License AC/L2.COMPOSITIONAL DATA :GAS :GASPROPERTIESAssociated Gas(Separator Sample)Methane 82.21Ethane 6.96Propane 3.39Isobutane 0.65N-butane 1.01Isopentane 0.28N-pentane 0.24Hexanes + 0.35Nitrogen 2.11CO 2 2.80H 2 S 0.00Specific Gravity 0.700BTU/ft 3 (gross) 1132STRATIGRAPHY (Jabiru-1A) :AGE UNIT FORMATION TOP(mKB)TERTIARY WOODBINE Undifferentiated 150.0GROUP Hibernia Formation 555.0CRETACEOUS BATHURST ISLAND GP Undifferentiated 920.0JURASSIC FLAMINGO GROUP Undifferentiated 1594.0TROUGHTON GROUP Plover Formation 1605.0
