BANCHORY, UK -- Xcite Energy says its latest appraisal well on the Bentley heavy oil field in the UK North Sea is progressing to plan.
Well 9/3b-6 has reached TD for the pilot section. This confirmed a 113-ft (34.4-m) oil column, around 40 ft (12 m) thicker than the 73 ft (22 m) prognosis, in a high quality Dornoch reservoir. The well also confirmed the prognosed oil/water cut at 3,729ft (1,136 m) TVD.
Xcite says the oil column has 100% net to gross, compared to a previously estimated average of 88%. This height of column suggests that an upside structure is present in the eastern half of the reservoir, which likely means an increased volume of oil in place.
The pilot section provided useful reservoir data for optimizing placement of the horizontal wellbore and for planning Bentley’s first-stage development.
It was then extended to test the Jurassic play concept, around 800 ft (244 m) deeper than the Bentley field Dornoch accumulation, and encountered 15 ft (4.6 m) of Jurassic reservoir with oil shows.
The pilot section has since been cemented and abandoned. Work has started on the horizontal sidetrack, which will flow test the Dornoch oil column.
