Australian Projects

Vincent and Enfield oil fields (production licence WA-28-L)

The Vincent and Enfield crude oil projects – located around 45 kilometres off Western Australia's North West Cape – are owned by a joint venture between MEPAU (40 per cent) and Woodside (60 per cent). The Enfield oil field began production in July 2006 and the Vincent project started in August 2008. Woodside operates both fields and uses floating production storage and offloading (FPSO) vessels to gather, store and offload oil from both projects.
