Quadrant Oil Australia Pty Ltd (QOA) is the registered operator for Petroleum Production Licence WA-13-L in offshore Commonwealth waters on the North West Shelf of Western Australia. QOA is a 100 per cent owned subsidiary of Quadrant Energy Australia Ltd. Quadrant proposes to plug and abandon two East Spar wells (East Spar-3 and East Spar-6) located in the permit area that forms part of the East Spar field approximately 36 km off Barrow Island.
The East Spar plug and abandonment activities will be carried out using a jack-up mobile offshore drilling unit. The purpose of the activity is to establish permanent well barriers with complete reservoir isolation downhole. Existing subsea infrastructure such as casing strings, the wellheads, Xmas Trees and flowlines, etc. will remain in place.
This activity is expected to commence in Q2 2018. A 500 m exclusion zone will be in place around the MODU when it is on location.
