Underground Blowout Causes & Killing
An underground blowout is the flow of formation fluids from one zone to another. Most commonly, we can recognize the underground Blowout by a lack of pressure response on the annulus. And this response will be while pumping on the drill pipe or by a general lack of pressure response. The underground Blowout can be most difficult, dangerous, and destructive. It can be most difficult because the conditions are not clear and can evade analysis.
