Ithaca Energy Inc. announces an update on drilling operations and certain operational setbacks at Beatrice and Jacky.
Both of the downhole electrical submersible pumps (“ESP”) in the Jacky production well, J01, have developed electrical faults under routine operations. Immediate plans are in effect to replace the pump units. Two ESP units were installed in early 2009 in the original completion of the J01 well, to maintain production. Technical experts have confirmed that both ESP units must be replaced. The well is now free flowing and gross production from the J01 well is approximately 700 barrels of oil per day (“bopd”)(approximately 335 bopd net to Ithaca); prior to this, under ESP support gross production was approximately 2,800 bopd (1,330 bopd net to Ithaca) as measured at the Nigg storage facility.
Drilling for the J03 well on the Jacky field has progressed, following rectification of the earlier operational difficulties. The J03 well is now at approximately 5,400 feet measured depth and 13” casing has been set.
The Company intends to continue to free flow the J01 production well until the J03 well has reached the target reservoir formation, the Beatrice “A” Sand, and been completed. This operation is anticipated to last until mid May. The Northern Enhancer rig (currently located over the Jacky platform) will then be utilised to undertake a workover operation to replace the failed ESPs in the J01 production well; this is expected to take a further 15 days. Production from the J03 well is planned to be optimised throughout the J01 work over operation period.
At Beatrice, the third workover well A28, on Beatrice Alpha, has been partially completed. The well, which was shut in in December 2009, is currently free flowing at approximately 130 bopd gross (65 bopd net to Ithaca). Meanwhile workover operations have transferred to well A21, the fourth and final well of the workover campaign. On completion of the A21 well workover, operations will transfer back to well A28 to retrofit an ESP to support production.
At the Athena development, drilling of the final development well, 14/18b-A2, is progressing on schedule. The well has been directionally drilled to the north west of the field and is now entering the top reservoir (Top Scapa A sands) at 8,900 feet true vertical depth subsea (“TVDSS”) drilling in a sub horizontal section. A final planned horizontal section of the well will be drilled from approximately 9,100 TVDSS. As scheduled, the remaining drilling and completion of the well as a producer is expected to take approximately 40 days.
The Company shall await the results of the J03 drilling and J01 ESP replacement operations before it confirms an updated overall forecast for net production in 2011. For provisional guidance purposes only, subject to Athena first oil in November 2011, success of the J03 well and the installation of replacement ESPs in J01 well, the Company anticipates that net annual average production for 2011 will be between approximately 5,100 and 5,550 bopd excluding any contribution from the recently acquired assets, announced on April 4, 2011.
