The Browse Basin Australian Petroleum Accumulations (APA) report provides a summary of petroleum discoveries and significant hydrocarbon shows found within the basin up until May 2014. This report differs slightly from previous reports in this series in that it documents inferred accumulations, whereas previous APA's reported ademonstrated discovery; that is, a discrete, measured recovery of petroleum from a test undertaken in an exploration well. The Browse Basin lies offshore from the remote Western Australia Kimberley region and hosts vast reserves of gas, some of which are rich in condensate, making it Australia's next major conventional liquefied natural gas (LNG) province on the North West Shelf. A recent upgrade of the super-giant Ichthys gas accumulation by operator Inpex estimated that the field holds 12.8 trillion cubic feet (Tcf) of gas. This accumulation is also estimated to contain 527 million barrels (mmbbl) of condensate, making it the largest hydrocarbon accumulation with recoverable liquids found in Australia since the discovery of the Gippsland Basin and Barrow Island oil fields in the 1960s, as well as being one of the country's top five gas fields. The Browse Basin continues to be a focus of exploration in which both international companies, such as Chevron, ConocoPhillips, Inpex, Shell and Sinopec, and the Australian explorers BHP Billiton, Nexus Energy, Santos and Woodside Energy, are capitalising on LNG opportunities.
