The Miller oilfield is a deep reservoir under the North Sea, 240 kilometres north-east of Peterhead in UKCS Blocks 16/7b and 16/8b. It was discovered in 1983 by BP in a water depth of 100 metres. Production from Miller field started in June 1992, and plateau production was from late 1992 to 1997 at rates of up to 150,000 barrels (24,000 m3) of oil and 255 mmscf of gas per day. Miller produced some 345 million barrels (54,900,000 m3) of oil during its lifetime.
The Miller field reached the end of its economic oil and gas producing life in 2007 when Cessation of Production (CoP) approval was received from the UK government. Preparations are currently under way to decommission the Miller platform, but the oil and gas pipelines will be preserved for future opportunities.
On 1 April 2009, sixteen people were killed in the crash of a helicopter carrying workers from the Miller field back to Aberdeen.
The reservoir consists of Upper Jurassic Brae Formation turbidites, 2 km deep, in the South Viking graben. The Kimmeridge Clay Formation is the source rock.
The Miller reservoir is located at a depth of 4,090 metres (13,420 ft) below sea level, it has an estimated area of 45 square kilometres (17 sq mi) and a maximum thickness of 110 metres (360 ft). Reservoir pressure is 45,000 kilopascals (6,500 psi) and reservoir temperature is 121°C.
As of 1999, BP estimated the total recoverable reserves from the field to be 335 million barrels (53,300,000 m3) of oil and 505 billion cubic feet (14.3×109 m3) of natural gas. Total oil in place for the reservoir is 620 million barrels (99,000,000 m3).
Gas export from Miller was via a sour gas pipeline system (Miller Gas System) comprising a 241 km, 30-inch-diameter (760 mm) sealine to St Fergus and then on via a 17.5 km 26-inch-diameter (660 mm) landline to Peterhead Power Station.
Miller oil was pumped via a 7.5 km-long, 18-inch-diameter (460 mm) export pipeline to the Brae A platform and then onwards via the Forties pipeline system to the mainland.
