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.
Claims5
A method of cementing a well with a cementitious composition containing a portion of the drilling fluid used to drill the well as a component of the cementing composition comprising the steps of:
- forming a cementitious composition comprised of,
- 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 of said cementitious materials;
- a drilling fluid present in said composition in an amount up to about 70% by volume of said cementitious material or materials therein;
- a hardenable resinous material selected from the group consisting of vernonia oil, epoxidized linseed oil or soy oil, an acrylic resinous material, an epoxy resinous material, a phenolic resinous material and mixtures of said resinous materials 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;
- and
- 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;
- introducing said composition into said well;
- and
- permitting said composition to set into a hard cementitious mass therein.
