US supermajor Chevron has chosen two deep-water gas fields to underpin the fourth-train expansion of its Gorgon LNG project in Australia. Chandon in block WA-268-P and Geryon in block WA-22-R will be exploited via subsea developments, it is understood.New large-diameter subsea gas pipelines will be required to bring the feedstock gas to the LNG plant on Barrow Island. The assets were selected from a stable of discoveries in the Greater Gorgon area.
