The Boom Down Under – Australian LNG projects drive thriving market for coal seam gas
At the end of 2013 approximately 3,330 CSG wells had been drilled in Queensland since 2010.    CSG-LNG projects will lead to the drilling of more than 30,000 CSG wells over the next nine years

Bare Liner Integrity Surveys Explained    
Conductive layer makes it possible to detect leaks on wrinkles and other non -conductive surfaces, and it allows the liner to be retested as often as necessary

Understanding Arc Testing of Geomembranes
The ‘Arc Testing Method’ can only be used on new construction bare geomembranes, requires a semi-conductive layer below geomembrane, and liner surface must be clean and dry.  Its main advantage is that it is highly accurate in detecting ‘Pin-hole’ size leaks.   This method has an average survey speed of 900 m2 per hour per operator – almost doubled that of Spark Testing.
