SMH: Why shale gas is still the next big thing
Mining companies are increasingly taking an interest in shale after it took off in the US, writes Paddy Manning.
Nobody knows the extent of the shale gas resource in Australia but the potential is big, perhaps big enough to reduce coal seam gas to a sideshow.
The federal agency Geoscience Australia set the theme of this week's annual Australian Petroleum Production and Exploration Association conference by estimating shale gas could double Australia's natural gas reserves, from 400 to 800 trillion cubic feet of recoverable gas.
The US shale revolution, spurred by the advent of horizontal drilling and fracture stimulation (or fracking) technology, transformed world energy markets in five years. MORE
