DANA Petroleum has reported successful flow testing of the recently drilled appraisal well on the Blackbird oil field in block 20/2a in the UK central North Sea.
Aberdeen-based Dana said yesterday that following detailed evaluation of data, the well, operated by Nexen Petroleum, was now assessed to have encountered 389 feet of gross pay and 90ft of net pay in good-quality oil-bearing reservoir sands.
It said the well had tested at a stable flow rate of 7,000 barrels of oil per day (bpd) via constrained facilities and would be suspended for future use as a producer through a potential tieback to the nearby Ettrick production vessel.
Dana also said that following the recent tie-in of two further development wells to the vessel, oil production rate from Ettrick had increased significantly from about 22,000bpd to more than 28,000bpd.
It added that as a result of these additional wells, Ettrick was expected to reach output levels of about 30,000bpd in the near future.
Dana said: “Development of the Blackbird oil field should bring significant new oil reserves through Ettrick and maintain peak oil production rates at the Ettrick production vessel for a longer period than originally planned, in addition to extending the overall field life of Ettrick.
“The Blackbird oil field will thus create value not only through its own development, but also add further value to the Ettrick oil field.”
Nexen is operator of both fields with a 79.73% stake in each.
Partner Dana has 12% in each and Faroese company Atlantic Petroleum has 8.27% in each.
