Project Profile
Value: Undisclosed
Location: Blocks 22/18 and 22/17, 130 miles east of Aberdeen, towards the northern end of the Central Graben area, UK
Water Depth: 91 metres / 300 ft
Length (pipelines): 3 mile (tie-back the Cayley production wells to the Montrose facilities) and 11 mile (production, water injection and gas lift pipeline)
Production: 40,000 barrels of oil equivalent a day (Shaw & Cayley)
Start-up Year: -
The Arbroath and Montrose fields are located in blocks 22/18 and 22/17, roughly 130 miles east of Aberdeen towards the northern end of the Central Graben area. The two fields have simple non-faulted, anticlinal structures separated by a structural saddle with only 15 ft of relief. The structures are a product of Alpine tectonism combined with differential compaction of the reservoir section. The hydrocarbons have a Kimmeridge Clay source and occur wholly within the Forties Sandstone interval. The oil is trapped by mudstones of the Sele Formation. The reservoir sandstones were deposited in a prograding submarine fan complex and have maintained an average porosity of 23% and a permeability of 80 md. The water depth in the area ranges around 91 metres (300 feet).
The MonArb Area Redevelopment Project (MAR) or Montrose Area Redevelopment (MAR) plan comprises redevelopment of the Montrose, Arbroath, Brechin, Arkwright, Carnoustie and Wood fields, and development of two new fields Cayley and Shaw. The two main fields Montrose and Arbroath are located in blocks 22/17 and 22/18 about 209km east of Aberdeen.
The project, which is being carried out by Talisman (51%) and Sinopec (49%), was approved by the UK Government in October 2012. The MAR project will extend the life expectancy of the existing six oilfields to 2030 to produce a further 100 million barrels of oil equivalent. Production from Shaw and Cayley is expected to start in 2017, with gross incremental production peaking at up to 40,000 barrels of oil equivalent a day.
