Location map - Activity: WA-20-L  (refer to description)

Santos WA Northwest Pty Ltd (Santos) and Santos Limited hold the title for WA-20-L in Commonwealth waters of the North West Shelf.

The activity occurs in Production License WA-20-L, approximately 105 km north of Dampier, Western Australia.

The two petroleum activities covered under the EP are:
- the ongoing gas seepage in the form of small bubbles emanating from the seabed into the water column at the Legendre Hub, Legendre South-1 and Legendre South-3 locations.
- the presence of the Legendre-1 wellhead, which has been in situ since the well was permanently plugged and abandoned in 1968.

Vessel-based surveillance, monitoring, inspection and research activities may be required in support of these two petroleum activities so for completeness have been described within this EP.
