Western Australia is now the nation's leading petroleum producer.
Mines Minister George Cash said the latest production figures from WA's Carnarvon Basin averaged 238,000 barrels of petroleum per day, overtaking Victoria's average production of 222,000 barrels per day for the same period.
"This is an important production milestone for the State's petroleum industry and this premier position will be consolidated when other projects come on track in the near future," Mr Cash said.
He said WA was already the nation's leading producer of gas and predictions on when it would be the leading petroleum producer were scheduled for early next year.
The early honours were achieved through the production of 65,000 barrels of petroleum per day from the North West Shelf project's Goodwyn development.
"Initial estimates were based on when the North West Shelf project's Wanaea-Cossack oilfield would begin operating later this year, but those production figures will now be the icing on the cake," Mr Cash said.
The Wanaea-Cossack project in the Carnarvon Basin is due to come on line this month and should reach full production of 115,000 barrels of petroleum per day by December. This will help boost WA's production to more than 400,000 barrels of petroleum per day.
"The value of petroleum production in this State has more than doubled in the past five years and this Government aims to maintain the impetus.
"With its abundant resources, a progressive infrastructure and close proximity to Asia there is every reason to be confident that WA's petroleum industry will continue its dynamic growth."
