Cementing compositions and the application of such compositions to cementing oil or analogous wells

A squeeze cementing composition comprising water and a solid particulate phase comprising cement, wherein the cement particles have an average particle size of from 0.3 to 10 micrometers;

• at least one first particulate material which is insoluble in water, is compatible with said cement, and has a particle size smaller than the particle of said cement, wherein at least one first particulate material has an average particle size of from 0.05 micrometers to 0.5 micrometers and is selected from the group consisting of a styrene-butadiene rubber latex, a silica ash, a manganese pigment ash, carbon black, and a polymer microgel;
• and water soluble fluid loss control additive such that the composition has a fluid loss of less than 30 ml per 30 minutes measured according to API Spec. 10, and the proportion of the at least one first particulate material relative to the cement is such that the combination of the cement and the at least one first particulate material has a packing volume fraction which is substantially maximized.
