Blackbird flow solidifies tieback potential to Ettrick FPSO in the UK North Sea

Dana Petroleum reported the successful flow testing of the recently drilled appraisal well at the Blackbird oil field, in the UK Central North Sea.

The 20/2a-9 well, operated by Nexen Petroleum UK, was drilled in a water depth of approximately 367 feet to a total measured depth of 12,000 feet, targeting a high quality Upper Jurassic oil discovery. Following detailed evaluation of all the gathered well data, it is now assessed that the well encountered 389 feet of gross pay and 90 feet of net pay of good quality oil bearing reservoir sands.

The well has been successfully flow tested, producing dry oil at a facilities constrained stable flowrate of 7,000 bopd through a 38/64" choke. The well has already been completed and will be suspended for future use as an oil producer, through a potential future tie back to the Ettrick FPSO.

Following the recent tie-in of two further development wells to the Ettrick FPSO, the oil production rate from the Ettrick field has increased significantly from around 22,000 barrels of oil per day to over 28,000 barrels per day. As a result of these additional wells, Ettrick is expected to reach oil production output levels of approximately 30,000 barrels of oil per day in the near future.

Development of the Blackbird oil field should bring significant new oil reserves through the Ettrick FPSO and maintain peak oil production rates at the Ettrick FPSO 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.
