Statoil extends lifetime for Oseberg Vestflanke

  • Exploration & Production

Statoil has received consent from the Petroleum Safety Authority (PSA) Norway to use Oseberg Vestflanke, located in the North Sea, beyond its originally planned life.

Oseberg Vestflanke is part of the Oseberg field and has been developed using subsea facilities tied back to the Oseberg field centre. The plan for development and operation (PDO) for Oseberg Vestflanke was approved in 2003. Production began in 2005 and was expected to finish in 2014.

According to the PSA, Statoil, the field’s operator, now estimates that Oseberg Vestflanke will be able to produce until around 2025, and has accordingly applied for consent for continued use.

The PSA has given Statoil consent to use subsea facilities, pipelines and control cables at Oseberg Vestflanke until December 31, 2025.

According to the PSA, a consent for use beyond the originally planned life entails that the PSA is of the opinion that the applicant has demonstrated having oversight of the technical conditions and has plans for maintenance and follow-up, such that the facilities and equipment may continue to be operated in compliance with regulatory requirements.
