Activity 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 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.
