Abstract
The Jabini Field lies in Block AC/L1 and AC/L2 in the Timor Sea offshore Australia's northwest coast . It began production in August 1986 from Jabiru1Aat oil rates of about 13 500 Stb/day. To date, six producing wells have beencompleted in the field, and by 30th April 1991 the field had produced 60.26million Stb of oil. There are two productive reservoirs in the field. The highly productive Wsp9reservoir is of excellent quality and is characterised by a strong water driveleading to a high recovery factor. It contains over 90 per cent of the field reservesand five successful oil producing wells have been completed in this reservoir, flowing at initial oil rates of between 15 000 and 20 000 Stb/day. The subsidiary structurally higher Wsp8 reservoir is of lower quality and is limited in extent tothe northeast corner of the field in the region of Jabiru-7. This reservoir containsthe remainder of the reserves and Jabiru-7 only has only been completed in thisreservoir, flowing at initial oil rates of about 3000 Stb/day. . The number of producing wells is limited by the floating platform which has onlyfour production risers. As a consequence only the four highest producing wells, currently Jabiru -1, -6,-8ST1 -11ST are produced at any time which has led to abandonment of the Wsp8 producer, Jabiru 7ST1. This well may be reconnected but may not have sufficient potential to warrant such an action while more productive targets remain in the Wsp9 reservoir. Appraisal of the Jabiru Field has been problematic because of the difficulties of interpreting seismic in the area. The present structure mapping interpretationmay change based on results of further drilling. This makes any forecasts of untapped oil based on structural interpretation somewhat uncertain.
