Santos progressing Spartan project offshore Western Australia

Offshore staff

ADELAIDE, Australia – Santos has issued updates on its development projects offshore Western Australia.

Drilling and completion activities for the Van Gogh Phase 2 infill program have finished, with tie-in and start-up activities to follow for the two remaining dual lateral wells.

The Varanus Island compression and offshore Spartan gas projects are progressing, as the company seeks to developing further reserves for export to Varanus Island.

Following the recent award of the subsea transport and installation contract for Spartan, the first offshore campaign should get under way in early 2022. The compression project is on track for start-up later this year.

In the Timor Sea, the $3.6-billion Barossa gas and condensate project is progressing with first gas expected during the first half of 2025. First steel for the FPSO’s hull was cut early last month at the shipyard in South Korea, three months ahead of plan, and manufacturing has finished of all wellheads and the first subsea tree.

Construction has started for the infield flowlines and the gas export pipeline, as has preliminary civil work to prepare for the Darwin LNG life extension project.

At the Bayu-Undan gas/condensate field, the second well in the infill campaign, W10, encountered gas-bearing reservoir and has since been completed and production tested at 30 MMcf/d.

However, pressure build-up analysis and well log data suggest well deliverability could improve, so a well intervention program will likely follow in the coming months. The third and final infill well spudded on Oct. 2.
