Mortar cement additives provide workability while retaining strength by employing a multi-stage polymer comprising a hydrophobically-modified, ionically-soluble polymer stage, the polymer being soluble at a pH of 6 and above; and an air-entraining agent. The additives also employ, as optional ingredients, set retarding agents and superplasticizers. Examplary methods of the invention involve addition of the multi-stage polymer and an air entraining agent to the mortar cement, preferably during intergrinding of Portland cement in the mill. Cement compositions comprising the polymer and an air-entraining agent are also disclosed.

The salt water thickener comprises ultrafine cellulose fibers and a water-soluble polymer and can thereby uniformly disperse the ultrafine cellulose fibers even in a liquid containing a salt. The salt water thickener of the present invention is uniformly dispersed even in a liquid containing a salt and therefore exerts a high viscosity. The salt water thickener of the present invention can also be used as an additive for a fluid. The salt water thickener of the present invention can be used for purposes, for example, subterranean formation processing.

The external surface of a tubular body such as well casing is coated with a substance that, upon exposure to cement, is unstable and degrades. After installation in a subterranean well and subsequent cementation, the coating degrades and forms a gap between the external surface of the tubular body and the cement sheath. Forming the gap is useful for obtaining optimal stimulation during the hydraulic fracturing of unconventional shale-gas formations.
