The Maureen field is located in Block 16/29a, 16/29b and 16/24b. The Group acquired its interest in the Maureen field in 2005, 2007 and 2008 from AOGL, BG and Apache North Sea Limited, respectively.
Fairfield has a 61.5 per cent., 49.9 per cent. and 49.9 per cent. operated interest in Licence P110 Block 16/29a (Maureen Field Area) and Licence P591 Blocks 16/29b and 16/24b, respectively.
Background and history
The Palaeocene Maureen Field was in production until 1999, operated by Phillips Petroleum. Total production from the Palaeocene was 217 mmbbls, which represents a recovery factor of 58% assuming a STOIIP of 400 mmbbls.
In partnership with Apache North Sea Limited and then Endeavour Energy Limited, detailed subsurface evaluation identified a number of drilling opportunities which proved to have been efficiently swept during earlier production when these were tested in 2007 and in 2009 by wells 16/29a-16 and 17.
Fairfield considers there is still remaining mobile oil in the Maureen Attic potentially recoverable by waterflood. The current re-development programme is based on the re-saturation or re-segregation phenomenon seen in analogue fields such as Dunlin, Angus and Piper. The static and dynamic models, developed in 2009, have now been updated with detailed well results in order to re-history match the model. This is intended to provide the best re-saturation and re-development evaluation, and work to conclude a final view of Palaeocene re-saturated volumes is ongoing. Additionally, there are believed to be multiple opportunities in deeper targets at Jurassic, Zechstein and Triassic levels.
Before decommissioning its fields, Fairfield will consult pro-actively with a wide range of stakeholders.
