Ithaca Finishes Stella Field Development Drilling

UK North Sea-focused independent oil firm Ithaca Energy reported Monday that it has successfully completed flow test operations on the fifth and final development well on its Stella field. Ithaca said well 30/6a-A3Y achieved a flow rate of more than 8,000 barrels of oil equivalent per day.

The well was drilled to a total measured depth of 14,267 feet, with a 2,137-foot gross horizontal reservoir section completed in the Ekofisk chalk reservoir – the secondary reservoir that underlies the primary Stella Andrew sandstone formation in which the first four Stella wells have been drilled. The well intersected a net reservoir interval of 2,073 feet, equating to 97 percent net pay.

A series of production flow tests conducted on the well over five days saw it produce at rates of up to 7,172 barrels of oil per day on a 48/64-inch choke, with a gas-to-oil ratio of approximately 1,850 standard cubic feet per barrel. The average flow rate over a 12-hour period was 8,080 boepd, comprising 6,191 bopd and 11.3 million cubic feet of gas per day. Fluid samples show that the oil gravity is approximately 39-degree API.

The well is currently in the process of being suspended and operations are scheduled to be completed in the coming days, Ithaca said. Upon completion the ENSCO 100 (350' ILC) rig will be demobilized from the field, marking the end of the Stella development drilling campaign. The five Stella was that have been drilled have achieved a combined maximum clean-up flow test rate in excess of 53,000 boepd.

Ithaca CEO Les Thomas commented in a company statement:

"We are very pleased to have delivered another successful flow test on the fifth and final well in the Stella development drilling program. The results of the Ekofisk well further de-risk forecast cash flows from the Stella field and the high oil content of the well is encouraging for maximizing liquids production during the period when the FPF-1 facilities will be operating at plateau gas production rates.

"We are also encouraged that there is further upside potential for reserves development in the Ekofisk formation."
