Portland cement compositions for use in high-temperature, high pressure wells are designed such that the lime-to-silica molar ratio is between 0.5 and 1.0, and the alumina-to-silica molar ratio is between 0.05 and 0.10. After curing and setting at temperatures between 85° C. and 300° C., the cement compositions form tobermorite as an initial and permanent calcium silicate hydrate phase.

The presently disclosed and/or claimed inventive concept(s) relates generally to a stone paint formulation. More particularly, the presently disclosed and/or claimed inventive concept(s) relates to a stone paint comprising a composition A and a composition B. The composition A comprises a latex emulsion, a rheology modifier, a coalescing agent, a biocide, a neutralizing agent and a solvent. The composition B comprises a sand. Additionally, the presently disclosed and/or claimed inventive concept(s) relates to a method of making the stone paint formulation by using the rheology modifier. The stone paint of the presently disclosed and/or claimed inventive concept(s) has enhanced resistance to water-whitening.

A method of controlling the equivalent circulating density of an epoxy resin, used to cement a wellbore, is provided. The method includes adjusting the cross sectional area of the annulus exit using a valve or other mechanism to increase or decrease the equivalent circulating density of the epoxy resin.

A low-dust composite building product is provided. The low-dust composite building product includes a binder system comprising one or more of a thermoset resin, a diluent, and a hardener; and a low-dust filler material comprising filler particles that have been pre-coated with a coating agent comprising one or more of the thermoset resin, the diluent, and the hardener from the binder system.

The present disclosure relates to coating compositions, kits, and methods of applying the same, for use with fireproofing materials. The coating compositions are effective to control the drying rate and shrinkage of fireproofing materials. The coating compositions are also able to be applied to fireproofing materials shortly after these materials have been applied to a substrate.
