Australia's biggest independent oil and gas producer said production fell to 20.7 MMboe in the second quarter from 22.2 MMboe in the same quarter last year.
Second-quarter revenue rose to $867 million from $825 million a year earlier, but missed a forecast of $976 million from Royal Bank of Canada. Quarterly sales volumes fell 3.8% to 20.3 MMboe.
The final commissioning of the Wheatstone LNG Train 1, Woodside's main source of short-term growth, is well advanced and nearing completion, it said. Operator Chevron Corp has said it is due to start producing in the middle of this year.
Woodside bought a stake in the $34-billion Wheatstone project in 2015, and it is set to contribute more than 13 MMboe to Woodside's annual output when complete.
