Abstract
A method for controlling the flow of subterranean water into a selected zone in a permeable subterranean carbonaceous deposit by injecting an aqueous plugging material into the permeable deposit through a plurality of wells to produce a plurality of injected areas of a size such that the injected areas overlap to form a barrier to the flow of subterranean water into the selected zone.
