THE proposed $1.6 billion Casper Oil Refinery planned for Gladstone is expected to produce 63,000 barrels of fuel a day.
It will employ 200 people in its operational phase, plus contractor staff employed in maintenance roles.
Construction worker numbers are expected to be between 1300 and 1500 to install the plant modules which will be fabricated overseas.
Casper Energy CEO Duncan McKenzie told yesterday's GEA major industry conference there was a significant need for more domestically produced fuels, especially diesel, in central Queensland.
He said Australia was lagging well behind in International Energy Agency's requirements in terms of fuel supplies, with the country holding around 23 days' supply where the IEA requirement was 90 days.
"It is fairly flippant in attitude to think lightly of the present position," he said.
"The majority of our imports currently come through Singapore with the crude mainly coming from the Middle East.
"Our refinery, because of the massive improvements in technology over the years, will be able to source cheaper and more sustainable 'sour heavy' crudes from countries where there is less political unrest and uncertainty, such as South America West Africa and central Asia.
"That's one of the main reasons we want to build in Gladstone.
"There are other reasons, such as an excellent deep water port which is capable of handling larger ships than at other ports, the excellent infrastructure which is already in place, and great rail links."
The plan is to have all approvals in place in time for a final investment decision by 2017.
