The Katherine Times article quoted Graham Sawyer. Basically the whole fracking process needs to be put on hold as it is just too risky - anyone surprised!
NT's first frack well has to be partially plugged.

Origin's Kyalla 117 is the first well to be drilled since the moratorium was lifted to explore for shale gas in the Beetaloo Base near Daly Waters.
The first new fracking well in the Northern Territory has run into trouble and had to be plugged.
Origin Energy's massive Kyalla Well looking for shale gas in the Beetaloo Basin had to be shut down after "operational challenges".
Origin joint venture business partner Falcon Oil and Gas issued a statement overnight said it had successfully drilled its exploration well vertically but had problems when it went sideways with a horizontal drill, a key part of fracking operations.
Origin wanted to drill the horizontal well between one to two kilometres in length but struck trouble after 700 metres.
"... operational challenges were experienced in maintaining adequate clean hole conditions and stability over portions of the horizontal production hole section appropriate to complete operations," Origin said.
"The initial horizontal production hole section will now be plugged in line with regulatory requirements. This will be followed by sidetracking drilling a new horizontal production line section."
Katherine Times understands the vertical well shaft is not being plugged and can still be used.
The company said the failure was "not uncommon in an exploration drilling program such as this".
But anti-fracking groups have called for the entire operation to be shut down until the failure is more fully reviewed.
Graeme Sawyer from NT Protect Country Alliance said the NT public deserved more than the scant detail and industry-speak contained within Falcon's statement.
"It could be that the driller can't keep the borehole open and that the rock is collapsing around the drill bit," he said.

"Risks will increase if Origin and Falcon push ahead to frack shale rock from a different horizontal well nearby.
"A halt on all activity and a full investigation of this incident should now be required until all the issues are made clear."
A NT Department of Primary Industry and Resources spokeswoman said Origin advised the department, as the regulator, it had an operational problem with their current exploration drill hole.
"Having assessed the current operation, Origin have decided to abandon the section of drill hole and drill a new horizontal hole," the spokeswoman said.
"As regulators, DPIR was informed of the planned abandonment of the section, as they need to comply with our regulations.
"The decision by Origin to hydraulic fracture this well will be made once the exploration drilling has b
