Individual well tests indicate that daily rates in excess of 20,000 bopd are readily achievable from a well deliverability stand point. Basker 2 and Manta 2A have exceeded expectations with rates averaging 8000 bopd. Basker 3 and 5, which are structurally higher are capable of producing at rates up to 5000 bopd, with all wells having wellhead pressures significantly in excess of delivery requirements on the FPSO at the present time.
Peak steady state production of 16,000 bopd has been achieved to date together with gas being injected at rates of approximately 26 million scfd back into the reservoir for storage. The steady state operation of the facility has been achieved for several hours but not for a full 24 hour period as the operating team fine tunes the controls on the much expanded production system.
It should be noted that currently the operation has been seriously affected by the extremely high ambient temperatures being experienced in SE Australia, with the gas cooling systems downstream of the compressor being adversely impacted. Once more normal ambient temperatures return to Bass Strait the well capabilities indicated above will be fully utilized.
Both vessels have been on location since mid-December, including the period of the severe adverse weather experienced between Christmas and New Year. Total production to date since commissioning commenced on 17 December 2006, has been approximately 220,000 barrels. This together with the production of 868,000 barrels during the EPT means that the fields have exceeded 1 million barrels of production.
Significantly the first cargo of oil was delivered to a refinery in Melbourne. The turn around time for the Basker Spirit was approximately 3.5 days. During this period individual wells were production tested to determine capacities indicated above and the resultant production was stored on the FPSO Crystal Ocean. Further the scheduled initial maintenance of the new compressor and driver was successfully completed during the absence of the Basker Spirit.
