摘要: Downhole tools that include an outer tubing disposed around an inner tubing for placement of a sealant mixture into a void in a subterranean formation and associated methods of use are provided. Furthermore, a method is provided for preparing a cement composition, which includes mixing a first cementitious component and an aqueous-based fluid in a first mixer to form an intermediate cement composition, and mixing the intermediate cement composition and a second cementitious component in a second mixer to form the cement composition.

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.
