METHOD OF TREATING PERMEABLE FORMATIONS

摘要

A method is provided for grouting zones of permeable geologic formations to prevent the flow of fluid through the grouted zone. In this method the formation is penetrated by a borehole. A blasting agent is disposed in the borehole contiguous to the zone to be grouted. The blasting agent is detonated to provide fractures in the zone of the formation which extend radially away from the borehole. The fractures are grouted to prevent the flow of fluid through the grouted zone.
