The Pyrenees Operations produces crude oil from the Ravensworth, Crosby, Stickle, Tanglehead, Wild Bull and Moondyne reservoirs with production commencing in 2010. Production is expected to continue to decline with end of field life predicted to be around 2035.
The Pyrenees field is situated within production licence WA-42-L and WA-43-L located on the North West Shelf in Commonwealth waters at 200 m depth, approximately 27 km northwest of North West Cape and 45 km northwest of Exmouth, Western Australia.
Subsea infrastructure connects the reservoirs to the Pyrenees Venture floating, production storage and offtake (FPSO) facility, which is installed on a disconnectable turret mooring. Produced gas is used for fuel and lift requirements with surplus gas reinjected into the Macedon Reservoir via a bi-directional well. Oil is exported from the FPSO to export tankers.
The drilling and tie-back of new wells associated with the Pyrenees Expansion activities will be subject to separate approvals for this phase of activities.
