ADELAIDE, Australia – Santos has issued updates on its field development and exploration projects offshore Northern and Western Australia.
The $3.6-billion Barossa gas and condensate project in the Timor Sea is 20% complete, with first gas exports to Darwin LNG set to start in the first half of 2025.
Barossa’s FPSO hull and topsides are under construction in South Korea and Singapore, and the first subsea tree has been delivered to Perth for integration testing. Manufacturing continues of the remaining subsea trees, infield flowlines, and gas export pipeline.
Development drilling should get under way by mid-2022, and pipelay before year-end. Onshore, the Darwin LNG Life Extension project is on schedule with preliminary civil works completed on site.
Elsewhere in the Timor Sea, Santos continues technical, commercial, and regulatory engagement for its proposed carbon capture and storage project at the Bayu-Undan field, with a FEED-entry decision targeted by mid-year.
In Western Australia, the Varanus Island compression and Spartan projects are progressing, both designed to support development of additional reserves through the Varanus Island facilities.
Pre-works activities have started on the John Brookes platform to tieback Spartan and prepare for the first (imminent) offshore campaign.
In the Bedout sub-basin, the Dorado development Stage 1 Offshore Project Proposal (OPP) phase has closed and the company has submitted the Stage 2 OPP to Australian regulator NOPSEMA.
The jackup Noble Tom Prosser is currently drilling the Dancer prospect, 7 km (4.4 mi) from the Reindeer field, to be followed by wells on Santos’ Pavo and Apus prospects in the Bedout basin, 35-40 km (21.7-25 mi) east of Dorado.
In the Petrel Sub-basin offshore Northern Territory, preparations continue for the South-West 3D seismic survey, and this should start after Shearwater GeoServices has completed the Keraudren Extension Phase 2 seismic survey in the Bedout sub-basin.
