> AUD $500 Million
Barossa 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. A Final Investment Decision to go-ahead with the Project has now been made.
The project will provide a new source of gas to the existing Darwin LNG facility, subject to suitable commercial arrangements being put in place. It will backfill the facility once the existing offshore gas supply from the Bayu-Undan offshore field has been exhausted.
Development of the large, discovered Barossa resource will extend the operating life of DLNG for an additional 15-20 years, thereby continuing to help meet future global demand for natural gas and contributing significant income and employment opportunities for Australia.
Santos currently holds a 62.5% operated interest in the joint venture along with partner SK E&S (37.5%). Santos is also a joint venture partner and operator in DLNG with a 68.4% interest.
Development Concept
The Barossa field sits within Santos' northern Australia portfolio, one of the company's core long-life, natural gas asset regions, and encompasses petroleum permit NT/RL5 located in Commonwealth waters, 300 kilometres north of Darwin, offshore Northern Territory.
The project comprises a Floating Production Storage and Offloading (FPSO) facility, subsea production system, supporting in-field subsea infrastructure and a gas export pipeline. The FPSO facility will separate the natural gas and condensate extracted from the field with the dry gas transported via the export pipeline for onshore processing
The proposed new gas export pipeline will be ~260 km in length and will connect to the existing Bayu-Undan to Darwin pipeline in Commonwealth waters. Condensate will be exported directly from the FPSO to offtake tankers.
Procurement Approach
The procurement approach for major scopes, such as the FPSO, Subsea, Export Pipeline and Drilling, will be through a combination of Engineering, Procurement and Construction/Installation (EPC/I), leasing or direct contracting and procurement by Santos.
Design of the facilities will be undertaken in accordance with the Project's design basis and include Company standards and specifications, Australian, ISO and other international standards and codes, including those broadly adopted in the Australian oil and gas industry and in line with local industry practice.
Santos has partnered with the Industry Capability Network NT to assist with Australian vendor identification and to raise awareness and communicate opportunities to provide goods and services to the project. To register a general expression of interest please submit below.

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.

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).
