Canvey Wick Walk

The Occidental Refinery (or Occidental Thames Refinery) was a planned oil refinery on Canvey Island, Essex, England. Located in the Thames Estuary, the partly-built, non-operational, six million tonne/year refinery was planned and constructed by Occidental Refineries Limited in 1970–5 and demolished in 1996–7.

Canvey Wick is a 93.2-hectare (230-acre) Site of Special Scientific Interest at the south-west corner of Canvey Island in Essex. It is owned by The Land Trust and 18.5 hectares (46 acres) is managed by the Royal Society for the Protection of Birds and Buglife as a nature reserve, who are working to bring more of the area under management and to improve public access.
