Vermilion Oil & Gas Australia Pty Ltd (VOGA) is the licensed permit holder of production licence area WA-14-L, located in Commonwealth waters in the Carnarvon Basin off the northwest coast of Western Australia, approximately 80 km northwest of Dampier and 110 km northeast of Barrow Island in water depths of approximately 54 m.
The Wandoo Field was discovered in 1991. Extraction of crude oil commenced in 1993 from a single unmanned monopod wellhead platform (Wandoo A) supporting a helideck and five production wells. In 1997, the Wandoo B production platform was installed and connected to Wandoo A by a subsea production pipeline. The Wandoo B production platform is supported on four concrete shafts that are attached to a Concrete Gravity Structure (CGS) that is comprised of ballast, product storage and water cells. The CGS sits on the seabed. The oil produced from Wandoo A is piped to the Wandoo B production platform. Oil is stored and then offloaded through flexible pipelines to a Catenary Anchor Leg Mooring (CALM) Buoy located 1.2 km north of the Wandoo B platform. A floating hose is used to transfer the oil from the CALM Buoy to export tankers moored to the CALM Buoy. The end of field life is currently modelled to be 2030.
Vermilion has been the operator of Wandoo since November 2005 and sole titleholder since 2007.
