Gorgon Stage Two drilling underway

Chevron and its joint venture partners will drill 11 new wells in the Gorgon and Jansz-Io gas fields in order to maintain supply to the existing gas facilities on Barrow Island.

Operations will begin in the Gorgon field, with seven wells planned for drilling by a mobile offshore drilling unit, before the remaining four wells are drilled in the Jansz-Io field.

The expansion project will also include system upgrades on Barrow Island and the offshore installation of 11 vertical subsea production trees, more than 46 km of production pipelines, almost 29 km of control umbilicals and 2,840 t of subsea structures.

Chevron Australia Managing Director Al Williams said the program would add to the already $40 billion spent by the project on goods and services in Australia.

“This development supports Chevron’s long-term supply of affordable, reliable and ever-cleaner energy to WA and our regional neighbours,” he said.

“This expansion will support local employment and contract opportunities on Gorgon for decades to come, with immediate benefits flowing through the drilling and completion activities, subsea infrastructure installation and local project management.”

Gorgon is one of the world’s largest natural gas projects with the ability to produce 15.6 million t/a of LNG.

The project is operated by Chevron, which owns a 46.3 per cent interest in the scheme, with ExxonMobil (25 per cent), Shell (25 per cent), Osaka Gas (1.25 per cent), Tokyo Gas (1 per cent) and JERA (0.417 per cent) possessing the remaining interest.
