The MonArb area is located in the Central North Sea roughly 128 miles east of Aberdeen. The area consists of nine producing fields covering blocks 22/17n, 22/17s, 22/18n, 22/18a, 22/22a, 22/23a, with production coming from Palaeocene Forties and Upper Jurassic Fulmar sandstone formations. Production is exported via the Forties Pipeline System to Cruden Bay, north of Aberdeen, with gas exported via the CATS pipeline to the CATS terminal at Teeside for processing.
Three platforms in the MonArb area operated by Repsol Sinopec at a water depth of 90m include Montrose Alpha commissioned in 1976, the Arbroath Platform commissioned in 1990, and the Montrose Alpha BLP commissioned in 2017. First production from the area was in 1976 from the Montrose fields, with subsequent production coming from Arbroath (1990), Arkwright (1996), Brechin (2005), Wood (2007), Godwin (2015), Cayley (2017) and Shaw (2017). The MonArb area benefitted from a £2 billion redevelopment project (and step-change in performance) that was completed in 2017.
Ithaca entered the MonArb area through the acquisition of Mauribeni’s interested in 2022. Continued development of the MonArb area is now premised with the addition of wells to maximize field recovery.
