[IAE-TSX] has success- fully completed flow test operations on the fourth development well on the Stella field, North Sea, achieving a flow rate of 12,005 barrels of oil equivalent per day (boe/d). Well 30/6a-B2Z is the fourth devel- opment well drilled on the Stella field. The well was drilled to a total depth of 14,461 feet, with a 2,396-foot gross horizontal res- ervoir section completed in the Paleocene Andrew sandstone reservoir. The well intersected high-quality sands across a net reservoir interval of 1,658 feet, equating to 69% net pay. As with the previous three Stella development wells, a cleanup flow test was performed on the B2 well in order to effectively remove the drilling fluids used to complete it. A maximum flow test was completed during the period, with the well flowing at a rate of 12,005 boe/d on a 48/64ths-inch choke. This rate comprised 5,901 bo/d and 36.6 million standard cubic feet per day of gas. The B2 well is currently in the pro- cess of being suspended, with operations scheduled to be completed by the end of September. The suspension configuration is such that the well can be brought on to production without the requirement for any further well intervention activity once the FPF-1 floating production facility is on location and hooked up. Upon completion of operations on the B2 well, the ENSCO 100 will be moved approximately 3 km to the main drill centre to drill a fifth well on the field, in the Stella Ekofisk reservoir that underlies the main Stella Andrew reservoir. The Ekofisk well is targeting light oil production in a chalk formation. The characteristics of the for- mation mean that initial production rates are likely to be lower than those displayed by the wells in the Andrew sandstone res- ervoir. Completion of the fifth well, which is expected to be in early 2015, will mark the end of the planned Stella devel- opment drilling campaign. Following completion of the B2 well suspension operations, four Stella Andrew reservoir development wells will have been completed, with the combined maxi- mum cleanup flow test results achieved by the wells being in excess of 45,000 boe/d. This well production capacity significantly de-risks the initial annualized production forecast for the Greater Stella area hub of some 30,000 boe/d (100%), 16,000 boe/d net to Ithaca. Les Thomas, CEO, said, "We are pleased to have delivered another successful flow test on this the fourth Stella field develop- ment well. The combined results of the four completed wells represent a major step for- ward in underpinning and realizing the full value of the Stella field development." n OIL & g a s
