way inversion structure. It is made of siliciclastic
fluvial and shallow marine sandstones. The field
is estimated to hold about 240 million barrels of
oil equivalent. Development of the field is
expected to present several challenges due to
harsh environmental conditions. The area is also
largely undeveloped with the absence of any
infrastructure.
Rosebank oil and gas field is located offshore of
the Shetland Islands, in the UK. It lies in blocks
213/26 and 213/27 of production licence 1026 in
1,100m (3,700ft) of water.
In 2011, Chevron completed the field development
plan for the project. The development plan aims
to achieve first production at the rate of
75,000bpd and 100,000 million cubic feet of gas a
day. About 15 subsea production wells and water
injection wells will be drilled from four subsea
manifolds.
Produced oil will be offloaded from a floating
production, storage and offloading (FPSO) on to
shuttle tankers. Gas will be processed on the
FPSO and exported onshore to the Shetland
Islands through a new pipeline, or through BP’s
West of Shetland pipeline to the Sullom Voe
terminal.
