Abstract
A method of cementing may include preparing a cement composition comprising: cementitious components comprising: a cement; a supplementary cementitious material; and nanoparticulate boehmite; and water; and introducing the cement composition into a subterranean formation.
Claims20
A method of cementing comprising:
- preparing a cement composition comprising:
- cementitious components comprising:
- a hydraulic cement;
- a supplementary cementitious material;
- nanoparticulate boehmite;
- and
- water;
- and
- introducing the cement composition into an annulus formed between a subterranean formation and a pipe string disposed in a wellbore in the subterranean formation.

A cement composition comprising:
- cementitious components comprising:
- a cement;
- a supplementary cementitious material;
- and
- nanoparticulate boehmite;
- and
- water.
4 more elements
A method comprising:
- providing a wellbore temperature and a time dependent compressive strength requirement;
- selecting a concentration of nanoparticulate boehmite wherein selecting a concentration of nanoparticulate boehmite comprises inputting the wellbore temperature and the time dependent compressive strength requirement into a boehmite concentration function and returning a concentration of nanoparticulate boehmite;
- individually selecting a concentration of a cement, a concentration a supplementary cementitious material, and a concentration water;
- preparing a cement composition comprising:
- cementitious components comprising:
- the cement;
- the supplementary cementitious material;
- the nanoparticulate boehmite;
- and
- the water,
- wherein the cement, the supplementary cementitious material, the nanoparticulate boehmite, and the water are present in the cement composition in the selected concentrations;
- and
- introducing the cement composition into an annulus formed between a subterranean formation and a pipe string disposed in a wellbore in the subterranean formation.
