Woodside Petroleum sees its production growing by about 15% between 2017 and 2020 due to supply from the Wheatstone LNG project and its own Greater Enfield project, both off Western Australia.

After 2020, output will grow further with the expansion of its Pluto LNG project in Australia and possible output from an oil project offshore Senegal, Australia's biggest independent gas producer said on May 23 at its annual investor briefing day.

Wheatstone LNG, operated by Chevron Corp. (NYSE: XOM), is on track to start producing in the next few weeks, Woodside CEO Peter Coleman said, adding that Woodside staff working with Chevron will push to bring costs down at the plant.

On growth projects, Coleman said the company hopes to reach a final investment decision on developing gas from its Browse asset off Australia's northwest coast in 2019.

The Browse project has been reworked three times over the past decade to curb soaring capital costs, once seen as high as $60 billion, as LNG prices have dropped due to a supply glut which is only expected to ease around 2022.

In its fourth incarnation, Browse is now viewed as a source to supply gas to the North West Shelf LNG plant from 2025, when the existing gas source runs out, rather than being developed as an expensive new LNG project.

"There's a very, very low appetite amongst the CEOs of our partner companies to partake in large capital investment decisions at this time," Coleman told investors.

The big challenge will be to secure agreement from other partners in Browse and the North West Shelf, including Royal Dutch Shell Plc (NYSE: RDS.A), BP Plc (NYSE: BP), BHP and Chevron, which all have other gas assets off Australia's west coast waiting to be developed.

"The moons have aligned for Browse, but it's still got a long way to go," Coleman said.
