摘要：
This invention relates to methods of using environmentally friendly cementitious compositions for terminating water flow in a subterranean formation such as in a fresh water zone or water aquifer. Preferred compositions of the present invention include a hydraulic cementitious material such as Portland cement, a viscosifying agent such as bentonite which increases the viscosity of the composition in the presence of water, and a vegetable oil.
