Quadrant Energy Australia Pty Ltd (Quadrant) is the registered operator for petroleum production Licence’s WA-214-P, WA-33-R, WA-55-R, WA-192-P, WA-29-L, WA13-L. Quadrant plan to further develop the gas condensate reserves of the Outer Barrow region in Commonwealth waters within these permit areas through the drilling of exploration and appraisal wells. Assuming a maximum success rate and favourable market conditions for exploration, Quadrant Energy estimates up to a maximum of 10 wells maybe drilled within these permits over the period of validity (5 years) of this Environment Plan (EP).
The duration for drilling each well will vary from approximately 20 to 80 days depending on the well design/reservoir target (with an average of 30 -40 days). In the event that unplanned events occur it is also possible that the estimated number of days may be exceeded on any one well.
During the activity, operations will be 24 hours per day. The first activity is scheduled to commence in quarter one 2016.
The Activity location (Project Area) is defined by petroleum permit permits WA-214-P, WA-33-R, WA-55-R, WA-29-L, WA-13-L and WA-192-P located within Commonwealth waters of the Carnarvon Basin in the NW Shelf region of Western Australia.
The Project Area is approximately 90 km from the closest mainland coast, 150 km from Dampier and 100 km from Onslow (closest population centres). Permits WA-55-R and WA-192-P are the closest to a land mass (the Montebello Group, approx. 7 km away) and are located within the Montebello Commonwealth Marine Reserve (CMR) sharing boundaries with the Montebello Islands State Marine Park (MP). The remaining four permit areas are to the west of WA-55-R and WA-192-P and out of these, only WA-214-P is also partially located within the Montebello CMR.
Within the Project Area, activities will be undertaken over smaller areas referred to as the Operational Areas. The Operational Area is defined as the permit area within which the MODU is connected or intended to be connected to the seabed. Only one MODU will be operating in the Operational Area at any point in time, however multiple support vessels and helicopters may be operating in the Operational Area at any one time.
