Abstract
The present invention provides improved cementitious compositions which can include drilling fluid as a component thereof and methods of cementing wells utilizing such compositions. The compositions are basically comprised of a cementitious material, water, a hardenable resinous material and optionally, drilling fluid in an amount up to about 70% by volume of the cementitious material in the composition.
Claims22
A cementitious composition comprising:
- a cementitious material selected from the group consisting of Portland cement, high alumina cement, slag, fly ash, condensed silica fume with lime, gypsum cement and mixtures thereof;
- a hardenable resinous material present in said composition in an amount in the range of from about 1% to about 50% by weight of said cementitious material or materials therein;
- water present in said composition in an amount in the range of from about 20% to about 175% by weight of said cementitious material or materials therein;
- and drilling fluid.
