Spallation is essentially catastrophic structural failure of rock when extreme heat is applied in a small area. As the rock heats, small pieces spring free of the face of the rock in micro explosions.<br \/>\n<br \/>\nSpallation drilling consists of a torch placed in close physical proximity to the rock face, the application of extreme heat to a small surface area, and removal of the waste material produced by spallation. The trick to this is, how does one get a flame to burn in the presence of water (used to remove the waste material) in an extremely high pressure (250 bar) environment? Chad and team reproduced this environment in a test facility at <a href=\"https:\/\/www.potterdrilling.com\/\" target=_blank\" >Potter Drilling<\/a> in Redwood City and discovered that not only was it possible to keep the flame active in the high pressure aqueous environment, but that temperatures necessary for spallation to occur (500C) were maintained.<br \/>\n<br \/>\nThis could be an important and cheaper alternative to rotary drilling.
