"The revenue streams are in US dollars and US fiscal policy hasn't helped us out much," he told a business forum.
"I'd like to think we can plan our way ahead of the cost increases."     
Last week, ConocoPhillips and joint venture partner Origin Energy approved the $14 billion first phase of their 9 million ton per year Australia Pacific LNG export project and Creeger said the company expects to make final investment decision on the second phase by the end of the year.  
The company also expects to move forward with a decision on how to develop its assets in the Browse Basin with joint venture partner Karoon Gas within the next 18 to 24 months, Creeger said.  
It is considering piping the gas to several locations including James Price Point, where Woodside Petroleum is planning to build an LNG plant, as well as Darwin, where ConocoPhillips currently has a plant. 
Other options include a floating LNG plant and developing the resource for domestic supply.  
Conoco and Karoon are now embarking on their next phase of the Browse Basin development which will see them drill five wells at a cost of $400 to $500 million, Creeger said.
