The sandstone for conventional is between the two layers of shale. To convert to unconventional gas, the drill has to go up slightly or down slightly, then horizontal. The company can say to the government that the infrastructure is already in place, then start the process for unconventional gas.

PEL154 - (Rawson Resources 100%, Operator)
Rawson Resources, through our 100% subsidiary Otway Energy, operates Petroleum Exploration Licence (PEL) 154.
Covers an area of approximately 300 km2
Both conventional and unconventional prospectivity
One exploration well – Year 5
The exploration licence comprises two separate blocks in the Otway Basin, South Australia. The eastern block is located approximately 16 km west of Mount Gambier, while the western block is located approximately 18 km southeast of Robe.

Jolly 1 was drilled to 2,406 metres, at which point mechanical problems were encountered in the Upper Sawpit Shale necessitating a side-track. 2,406 metres where presumably drill head could not go further. Please look at depth side grid. It appears to be around intersection of drill hole and fault. Also please note that the drawing shows that faults have been drilled through.

States such as Oklahoma, Texas, Kansas and Ohio are being hit by earthquakes that appear linked to oil and gas activity. While the quakes are far more often tied to disposal of drilling waste, scientists also increasingly have started pointing to the fracking process itself.
"Certainly I think there may be more of this that has gone on than we previously recognized," Oklahoma Geological Survey seismologist Austin Holland told colleagues last week.
In addition to what Holland has seen in Oklahoma, a new study in the journal Seismological Research Letters concludes that fracking caused a series of earthquakes in Ohio a year ago. That follows reports of fracking leading to earthquakes in Canada and across the Atlantic in the United Kingdom.
Hydraulic fracturing, known as fracking, is when massive amounts of high-pressure water with chemicals is pumped underground to break shale rock and release the oil and natural gas inside.
The process is responsible for the nation's energy boom since 2008, as it has allowed access to oil and gas trapped in the shale. But at the same time, earthquakes have spiked in the central and eastern United States.
Before 2008 Oklahoma averaged just one earthquake greater than magnitude 3.0 a year. So far this year there have been 430 of them, Holland said. (2014)
