Furzey Island is an island in Poole Harbour in the English county of Dorset. The island lies to the south of the larger Brownsea Island. Seen from the water, or adjoining land, the island looks like another wild pineclad island. However, hidden in the trees are twenty-two oil wells split into 2 well-sites for the Wytch Farm Oil Field, which is linked by pipeline to Hamble on Southampton Water. The rarely seen tall oil rig, can sometimes be a big landmark of Southern Poole Harbour and the main landmark between Brownsea and Furzey. The well-sites are manned 24 hours a day.
