THE controversial process of hydraulic fracturing or "fracking" in coal-seam gas extraction could occur at up to eight times the rates suggested by the Queensland government.
The Queensland Department of Energy has played down the extent of fracking by repeatedly stating that the process had occurred at "just 5 per cent" of coal-seam gas wells operating in the state.
Trevor Brown, vice-president of exploration at gas giant Santos, widely accepted to be at the forefront of the local CSG industry, said fracking was expected to occur at between 10 and 40 per cent of CSG wells.
Rob Millhouse, general manager of government affairs for CSG major QGC, said the group expected to frack about a third of its CSG wells. "We expect to frack about one-third of our wells, but between 10 per cent and 40 per cent would be right as a general rule," he said.
