NT AUSTRALIABarossa is an offshore gas and light condensate project being progressed by the Barossa Joint Venture comprising Santos Offshore Pty Ltd (Santos) as Operator and SK E&S Australia Pty Ltd.
WA AUSTRALIAThe Dorado oil field contains 140 mmbbls (2C, 100%) of oil. It is located in the Bedout basin, approximately 150km north of Port Hedland in Petroleum permit WA-437-P. The project will be developed jointly in line with the equity split of Santos Offshore Pty Ltd 80% and Carnarvon Petroleum Pty Ltd 20%.
The offshore resource would be developed with up to 16 platform wells drilled by a jack-up drilling rig. These would be connected back to an adjacent Floating Production, Storage and Offloading facility (FPSO) moored in 95 metres of water above the Dorado field.
The proposed FPSO unit will have processing facilities to stabilise and store the oil and compress and re-inject gas to the reservoir.
NT AUSTRALIAAs part of the Barossa development, Allseas will be responsible for the installation of the offshore rigid gas export pipeline and associated end structures (PLETs), as well as installation of mattresses for span correction, buckle initiation and pipeline crossing.

As part of the Barossa Offshore Project, Santos has selected BWO as the contractor to provide the FPSO Services.
NT AUSTRALIAThe Darwin LNG plant (DLNG) is a single train liquefaction and storage facility located at Wickham Point on Darwin Harbour, Northern Territory, Australia. DLNG is currently receiving gas from the Bayu-Undan field in the Timor Sea and converts it into LNG. DLNG was commissioned in 2006 and has a design life to 2027. Bayu-Undan produced its first gas in 2004 and is now approaching the end of field life.
The DLNG Life Extension Project (the Project) seeks to utilise the shutdown window created by Bayu-Undan end of life to prepare the DLNG facility for backfill from the Barossa field, by undertaking several brownfield work packages.
WA AUSTRALIAThe Dorado field is located in the Bedout sub-basin, approximately 150km North of Port Hedland in Petroleum permit WA-437-P. The project will be developed by Santos in a joint venture with Carnarvon Petroleum. Development is planned to consist of a disconnect able Floating Production, Storage and Offloading facility (FPSO) with a 16 slot Wellhead Platform (WHP) using a jack-up drilling rig, connected via subsea production and injection flowlines, risers and umbilical.

Santos is a global low-cost producer of oil and gas committed to ever-cleaner energy and fuels production with operations across Australia, Papua New Guinea, Timor-Leste and North America.
NT AUSTRALIAThe Bayu-Undan Carbon Capture and Storage (CCS) Project targets the capture of up to 10 Mtpa of CO2 at a Darwin hub - initially from the Darwin LNG facility (DLNG), with potential future expansion to proximal 3rd party. Captured CO2 will be transported to, and stored in, the offshore Bayu-Undan reservoir (in Timor Leste waters).
