Comments

Enoch lies partly in the UK Continental Shelf (UKCS) and the Norwegian Continental Shelf (NCS)and is located south-west of the Norwegian Glitne field. A Field Development Plan was submitted in May 2005 and Government sanction received in July 2005.  A Unitisation and Unit Operating Agreement was finalised in July 2005. Enoch will be developed as a subsea tieback to the Marathon operated Brae Alpha platform, located in the UKCS, some 15km to the north. At Brae the wellstream will be processed for further transport in existing export infrastructure. First Oil currently expected 4Q 2006.
