Ithaca Updates on Greater Beatrice Production
Ithaca Energy has offered additional guidance on production performance from the Jacky and Beatrice oilfields in the Greater Beatrice area of the UK North Sea.
Cumulative production since start up on 6th April, 2009 from Jacky now exceeds 1.5 million barrels ('mmbbls') gross (0.713 mmbbls net to Ithaca). Proved reserves assessed by independent petroleum consultants, Sproule International Limited ('Sproule') at year end 2008 were 1.422 mmbbls gross. A revised reserves report is currently being prepared by Sproule.
Overall, Ithaca expects to achieve its target production rate of 5,000 barrels of oil per day ('bopd') net to Ithaca for the second half of 2009.
The recently completed Jacky water injection well is now operating with injection rates over 18,000 barrels of water per day. Revised Jacky oil production rates will be reported once injection rates have been stabilized.
During September, Jacky oil production was shut in, as planned, for 12 days to allow drilling rig operations. Nevertheless, oil production from Jacky and Beatrice averaged 6,296 bopd (3,044 bopd net) over the month. Daily peak rates were sustained at over 13,000 bopd gross.
During October the downhole pump in the Jacky production well was slowed down to prevent reservoir pressure falling below acceptable operating levels. This combined with a further 2 days of planned downtime due to drilling operations held Jacky production slightly below that seen in previous months and combined production from Jacky and Beatrice averaged 10,078 bopd gross (4,853 bopd net to Ithaca). The pump rate is expected to be increased during November as the reservoir responds to the pressure support provided by the new water injection well.
The drilling rig Ensco 80 has now moved to the Beatrice Bravo platform where it will conduct workover operations on two currently shut-in production wells. These interventions are being undertaken to boost production from the field and work will last approximately one month. In one well an existing standby downhole pump will be activated and in the other a failed pump will be replaced.
Partners in the Jacky field are Ithaca (47.5%), Dyas UK Ltd (42.5%) and North Sea Energy (UK) Ltd (10%)
Partners in the Beatrice Field, including Beatrice Bravo are Ithaca (50%) and Dyas UK Ltd (50%).
