Beatrice oil field

The Beatrice Oil Field is a small oilfield consisting of 3 platforms located 24 km off the north east coast of Scotland. It began operations in 1980 with the field finally being decommissioned in 2017.

Work is ongoing to begin removing all structures.

The 84 turbine Beatrice Offshore Windfarm now sits in the same area and was completed in 2019.

Beatrice was the first field to be developed in the Moray Firth area, and at 24 km from the shore that can be seen from the land. Beatrice comprises 4 conventional steel platforms: Beatrice A, and two single satellite platforms B and C.

First discovered and developed by geologist Jack K. Larsen with Mesa Petroleum, and named after Mesa's founder T. Boone Pickens' wife, it covers an area of around 23 km2. The oil is 2,100 m below the sea bed and about 8,000 tonnes of oil has been produced each day. Operation of the Beatrice oil field was then transferred to Talisman in 1997 until it was leased to Ithaca Energy who took over operations in 2008. Talisman resumed ownership of the field in 2015 from Ithaca Energy and is preparing to decommission the field.

The Beatrice Alpha complex consists of 2 platforms bridge-linked (50.5 m): 1 drilling/quarter platform (AD) and 1 processing/power generation (AP).

Beatrice B satellite platform is located to 3 miles north-east of the A complex, and was installed later. It is a drilling and a water injection platform. Beatrice C is designated a satellite water injection facility and was installed in September 1984. It pushes oil from the south-west end of the reservoir in direction of A. B and C are linked by pipelines with A. Fabrication details are given in the table.

Crude oil was heated to improve separation and flowed to one of two parallel 3-stage Separators (A and B) where gas was flashed off and produced water removed. Each separator had a capacity of 50,000 barrels per day. From the Separators oil was routed to the Crude Oil Transfer Pumps, through fiscal metering and into the 16-inch pipeline to shore.
