Abstract
An exemplary method includes introducing a treatment fluid comprising nano-hydraulic cement into a subterranean formation. The treatment fluid may include a drilling fluid, a completion fluid, a stimulation fluid, a well clean-up fluid or a cement composition. Another example method comprises introducing a cement composition comprising nano-hydraulic cement, hydraulic cement, and water into a subterranean formation; and allowing the cementing composition to set in the subterranean formation. An example well treatment fluid comprises nano-hydraulic cement.
Claims20
A method of cementing comprising:
- introducing a cement composition comprising nano-hydraulic cementitious particles, a hydraulic cement having a mean particle size greater of about 1 micron or greater, and water into a well bore, wherein the water is present in an amount between about 33% to about 200% of the cement composition, wherein the nano-hydraulic cementitious particles have a mean particle size of between about 20 nanometers to about 100 nanometers, the nano-hydraulic cementitious particles being selected from the group consisting of a Portland cement, a pozzolanic cement, a gypsum cement, a soil cement, a calcium phosphate cement, a high-alumina content cement, a silica cement, a high-alkalinity cement, and any combination thereof;
- and
- allowing the cement composition to set in the subterranean formation by reaction of the nano-hydraulic cementitious particles and the hydraulic cement with the water to form a hardened mass.
