Atteris bags Dorado Feed contract
Engineering services provider Atteris on September 13 announced that Australian energy company Santos has awarded it the subsea front end engineering design (Feed) contract for the Dorado development offshore Western Australia.
The engineering design work will include flow assurance definition and design of the subsea system connecting the wellhead platform to the FPSO including the flexible flowlines, dynamic risers and a mid-water arch structure.

The Dorado field is located within the Bedout sub-basin, some 150 km north of Port Hedland, Western Australia, in a water depth of approximately 95 m. According to Santos, Dorado is a very low CO2 reservoir with approximately 1.5% CO2 and reinjection of gas in the initial phase, making it one of the region's lowest emission intensity oil projects.
Dorado is an integrated oil and gas project which is planned to be developed in two phases. The initial development involves the production of oil and condensate through a wellhead platform and FPSO. Gas will be reinjected in the initial phase to enhance oil and condensate recovery, followed by a planned future phase of gas production to backfill Santos' domestic gas infrastructure in Western Australia.
Santos has an 80% interest in the Dorado project and is the operator. The remaining interest is held by Carnarvon Petroleum. In June, the project entered the Feed phase.
