Claims49
A method of sealing a subterranean zone penetrated by a well bore comprising:
- preparing a cementing composition comprising cement, acrylonitrile butadiene styrene polymer, and water;
- placing the cementing composition into the subterranean zone;
- and
- allowing the cementing composition to set therein.
A method of sealing a subterranean zone penetrated by a well bore comprising:
- preparing a cementing composition comprising cement, acrylonitrile butadiene styrene polymer, and water, wherein the cement is Portland cement, pozzolan cement, gypsum cement, aluminous cement, silica cement, or alkaline cement;
- placing the cementing composition into the subterranean zone;
- and
- allowing the cementing composition to set therein.
A method of sealing a subterranean zone penetrated by a well bore comprising:
- preparing a cementing composition comprising cement, acrylonitrile butadiene styrene polymer having a particle size of less than 1 mm, and water;
- placing the cementing composition into the subterranean zone;
- and
- allowing the cementing composition to set therein.
A method of sealing a subterranean zone penetrated by a well bore comprising:
- preparing a cementing composition comprising cement, acrylonitrile butadiene styrene polymer, silica flour and water;
- placing the cementing composition into the subterranean zone;
- and
- allowing the cementing composition to set therein.
A method of sealing a subterranean zone penetrated by a well bore comprising:
- preparing a cementing composition comprising cement, acrylonitrile butadiene styrene polymer, and water present in an amount sufficient to form a pumpable slurry, wherein the acrylonitrile butadiene styrene polymer is present in a range of 5% to 30% by weight of the cement;
- placing the cementing composition into the subterranean zone;
- and
- allowing the cementing composition to set therein.
