Rosebank oil and gas field
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 (38×106 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]
