One of the few OECD countries that is a significant net hydrocarbon exporter, Australia contains impressive quantities of petroleum, natural gas and coal reserves and exports roughly two-thirds of its total energy production. Australia, which has major offshore natural gas fields feeding the Gorgon, Wheatstone and Pluto LNG developments, is the word's fifth-largest exporter of liquefied natural gas. As of 2009, Australia holds proven oil reserves of 1.5 billion barrels and some 30 Tcf of proven natural gas reserves.
Production engineers monitor and evaluate the production and efficiency of an oil or gas well. They develop methods to improve extraction, oversee drilling activities and will determine the need for new or improved tools. One of their main responsibilities is to evaluate the flow between the reservoir and the wellbore. Production engineers monitor the entire production process and will design completion systems and select equipment that will increase production rates. Production engineers are usually petroleum engineers, however sometimes an engineer from a different discipline will be trained on production engineering tasks.
