I wish that was true, but i can say not every well has a TJ/d come out , only specific area. SIS wells is an ongoing concept that is still very relevant and happening across thick coal seams in specific area only. I only raise SIS concept is because the coals can be lined with fibre glass casing or even steel casing (if regulation allows, i.e. no future mining) therefore collapse of coals or production can be managed.

Also to clarify, Surat basin coals are smaller seams spread across 300 m (one thick seam at the top) and they do not have SIS concept applied. Only Bowen Basin which has three disticnt thick coal seams. The definition of thick here is 5 - 10 m each seam.
