Dorado Development

Project at a glance
The Dorado oil field 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 80% and Carnarvon Petroleum 20%.
The offshore resource is expected to 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.
Santos anticipates that the development will have an estimated 10-15 years oil life. A Front End Engineering Design (FEED) decision is targeted for 2021, followed by a Final Investment Decision (FID) in 2022 and production Ready For Start Up (RFSU) some 4 years later.Targets are subject to all necessary joint venture approvals, regulatory approvals and/or appropriate commercial arrangements.
The Dorado contracting strategy has been developed around four main work elements:
- Drilling & Completions (D&C);
- Supply and Installation of Offshore Hardware, including a Well Head Platform, Umbilicals, Risers & Flowlines;
- Engineering, Procurement, Construction & Commissioning of a Floating Production Storage and Offloading facility (FPSO); and
- Logistics.
The procurement approach for these major scopes, including FEED, will be through a competitive tendering process with a mix of Engineer Procure Construct / Install (EPC/I), purchase or leasing as appropriate. The majority of procurement activity will take place post-FID. Under each of these work elements, where applicable, successful Tier 1 contractor(s) will assume responsibilities as the 'Procurement Entity' acting on behalf of Santos as the 'Project Proponent'.
For all itemised packages that result in a sub-contract to the Procurement Entity, each Procurement Entity will be required to conduct their procurement activities in line with the actions outlined in this plan, providing full, fair and reasonable opportunity for Australian entities to participate where capable and competitive
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.
As 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.

The 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.
A proudly Australian Company, Santos is the biggest producer of domestic gas in Western Australia and has been operating in the west since its first oshore discovery, in the Carnarvon Basin, in the early 1980s.
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.
The 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).
