Woodside Petroleum has recorded a drop in revenue caused by the decline in oil prices.
The Australian company said a cyclone in the west of the country had also affected profits.
The company reported sales revenue of $1.4billion in the March quarter – a 16% falls from the year before.
However the company said despite a weaker start to the year, Woodside said it was on track to reach its 2015 base production target of 84million to 91million barrels of oil equivalent.
Production at Pluto was halted after a drifting oil rig was knocked loose during Cyclone Olwyn.
It caused a six-day shut down at its Pluto operations off Western Australia’s north coast.
The rig had been drilling at Chevron’s Wheatstone LNG project nearby.
