Woodside Energy has issued updates on its field development and decommissioning programs in Australian waters.

Woodside has constructed a pipeline to transport gas from Pluto LNG to the North West Shelf Project’s Karratha Gas Plant.

Woodside Energy has issued updates on its field development and decommissioning programs in Australian waters.

The company has raised its cost estimate for the Scarborough offshore gas development by 4% to $12.5 billion (Woodside’s share $8.2 billion). Much of the increase is related to maturing the scope of the modifications to Train 1 at the onshore Pluto LNG complex that will receive Scarborough’s production.

At the end of the second quarter, Scarborough and work on Pluto Train 2 were 67% complete. Fabrication of the floating production unit hull is progressing, while the living quarters module has been installed on the topsides, which is now structurally complete.

Offshore trunkline installation has switched from 36-inch to 32-inch pipe and is more than 50% complete. Two development wells have been drilled, one of which has been completed; reservoir quality is in line with pre-drill estimates.

All three flowlines have been installed and tested.

Environmental approvals uncertainty is impacting all offshore activity, Woodside stated.

Elsewhere offshore Western Australia, Woodside’s Griffin, Stybarrow and Enfield decommissioning campaign continues with ~50 km of flexible flowlines and umbilicals recovered during the second quarter. The final two of Enfield’s 18 xmas trees were removed and wellhead severance started, with four completed at the end of the quarter.

In the Gippsland Basin offshore Victoria, offshore installation has finished of the Kipper compression modules, with hookup activities set to start in the current quarter. As part of the Gippsland Asset Streamlining project, the Halibut platform has ceased producing oil, as planned.

The Gippsland Basin joint venture is also progressing the FEED for removal of platforms no longer in use and continued to execute preparatory decommissioning activities. In the Bass Strait, the light intervention vessel Q7000 is performing P&A of two subsea wells.

Offshore Congo, Woodside is a partner in the currently drilling of Niamou Marine-1 well, operated by TotalEnergies on the Marine XX permit.
