This reservoir, which contains 45 million barrels of oil equivalent, will be connected to BP’s Andrew platform and enable production to be extended to 2020 and beyond.
BP said production from the reservoir is forecast to peak at 45,000 barrels per day and be exported through the existing Forties pipeline system to Kinneil and the CATS pipeline system to Teesside.
The project will install a new subsea system and caisson onto the Andrew platform in order to access the new reservoir.
The Andrew platform will undergo major modifications including the addition of a 750-ton process module.
Construction is expected to be completed over two years, and the new facilities are scheduled to commence production in 2013.
BP holds a 77.06% interest in the project with ENI and Summit Petroleum holding 16.67% and 6.27% interests, respectively.
According to BP, Kinnoull is the largest of three reservoirs which are being developed as part of the Andrew Area developments project, and contains 45 million barrels of oil equivalent.
