    Abstract: Methods of servicing a wellbore in contact with a subterranean formation include passing an ester-based fluid into the wellbore and reducing a temperature of the ester-based fluid by an amount effective to cause the ester-based fluid to set, e.g., by from about 10° F. to about 20° F. The ester-based fluid includes a water in ester-based oil emulsion, a pH controlling additive, e.g., hydrated lime, in the water-phase, and an emulsifier to stabilize the pH controlling additive. Cooling the ester-based fluid causes the emulsion to destabilize, resulting in the release of the pH controlling additive. This release raises pH of the ester-based fluid by an effective amount to cause it to set. Wellbore servicing fluids comprising the foregoing ester-based fluid may be employed as environmentally friendly sealants or spotting fluids in wellbores.

    Abstract: A cementitious composition comprising hydraulic cement, not more than 25% of water by weight of the composition, and water soluble or dispersible (co)polymer in a proportion of 1 to 15% by weight of the hydraulic cement in the composition, the cement and (co)polymer being selected such that a test composition comprising 100 parts by weight of cement, 5 parts by weight of (co)polymer, and 16 parts by weight of water when extruded in a capillary rheometer undergoes an increase of at least 25% in shear stress when a ten-fold increase in the shear rate of the test composition from the capillary of the rheometer is effected. Also a cementitious product produced by setting of the composition. The (co)polymer is preferably a partially hydrolyzed poly (vinyl acetate). The cementitious product may have a flexural strength in excess of 100 MPa.

    Abstract: The present invention relates to a slurry containing water, amorphous silica particles having a particle size less than 1 μm and silica flour with a particle size between 2-200 μm. In order to stabilize the slurry, the slurry contains a polysaccharide. The invention further relates to a method for the production of a slurry containing water, amorphous silica having a particle size below 1 μm, and silica flour with a particle size between 2-200 μm, where a polysaccharide is added to a slurry of water and amorphous silica, whereafter the silica flour is mixed into the slurry of amorphous silica.
