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.

32. 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. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. A method of cementing comprising:
-
providing a cement composition comprising nano-hydraulic cementitious particles and water, 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; and allowing the cement composition to set by reaction of the nano-hydraulic cementitious particles with the water. - View Dependent Claims (46, 47, 48, 49, 50, 51)
