Woodside is submitting a revision of the North West Shelf (NWS) Project’s Angel Platform Operations Environment Plan in
accordance with the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009 (Cth). The Environment
Plan is being resubmitted to account for the production from a single well tieback located in the Lambert Deep reservoir. There
are a further three production wells tied back to the Angel facility via rigid flowlines that are no longer normally producing from
the Angel reservoir due to high water content and have been shut-in. The Environment Plan will also include a number of
exploration wells not linked to the production systems.

The Environment Plan will cover the Angel Facility, including the Lamber Deep Tieback, operated by Woodside on behalf of the
North West Shelf (NWS) Project, as well as a number of exploration wells not linked to the production systems. The participants
include Woodside Energy Ltd, BHP Petroleum (NWS) Pty Ltd, BP Developments Australia Pty Ltd, Chevron Australia Pty Ltd,
Japan Australia LNG (MIMI) Pty Ltd and Shell Australia Pty Ltd.

The Angel facility is located in Commonwealth waters within licence areas WA-3L, WA-14PL and WA-16L. The Angel platform is
situated approximately 125 km north-west of Karratha in Western Australia and has been operating since 2008. Angel is an
offshore not normally staffed (NNs) production platform that will produce from the Lambert Deep reservoir. Gas and
condensate from this reservoir is processed on the Angel platform then transported via an export pipeline to the North Rankin
Complex, and then onshore to the Karratha Gas Plant (KGP) for processing.
