The Rosebank oil and gas field lies west of Shetland.[1][2] It is operated by Equinor; Suncor and Siccar Point.[1] The discovery well was drilled in 2004. A final investment decision for Rosebank is planned to be taken by May 2022.[1]

Ocean depth is 1,100 metres (3,600 ft). The discovery well, drilled to 2,743 metres (8,999 ft), flowed 6,000 barrels per day (950 m3/d) of 37° API light oil from a deposit 24 metres (79 ft) thick. [3]

Geology[]

The deposit is contained in layers of sandstone which lie between layers of basalt making use of seismic imaging difficult and expensive. It is estimated that 240 million barrels (38×10^6 m3) of oil and gas could be recovered.[2]

Practical considerations[]

Weather conditions are extremely difficult. Superstructure is designed to withstand 100-foot (30 m) waves. High petroleum prices and favorable tax treatment is needed.[2] Bringing gas to market requires finding a way to finance a pipeline which would combine production from several fields in the West of Shetland area into a gas export pipeline.[4]
