Esso Australia Pty Ltd., a subsidiary of ExxonMobil Corp. and current operator of the Gippsland basin oil and gas fields in Bass Strait offshore eastern Victoria, has started drilling the Turrum Phase 3 project in Australia.

This $350-million investment will see the VALARIS 107 jack-up rig drill five new wells into Turrum and North Turrum gas fields within Production License VIC/L03 to support Australia’s east coast domestic gas market. The new wells will be drilled from Marlin B platform, about 42 km off the Gippsland coastline, southeast of Lakes Entrance in water depths of about 60 m, according to a 2025 information bulletin.  

Turrum Phase 3, which builds on nearly $1 billion in recent investment across the Gippsland basin, is expected to be online before winter 2027, the company said in a post to its LinkedIn account Mar. 24.

In 2025, Esso made a final investment decision to develop the Turrum Phase 3 project targeting underdeveloped gas resources.

The Gippsland Basin joint venture is a 50-50 partnership between Esso Australia Resources and Woodside Energy (Bass Strait) and operated by Esso Australia.
