Disclosed are spacer fluids and methods of use in subterranean formations. Embodiments may include use of consolidating spacer fluids in displacement of drilling fluids from a well bore annulus.

Consolidating spacer fluids and methods of use

Methods and compositions are provided that relate to cementing operations. Methods and compositions that include pumice in geopolymer cement compositions comprising slag.

Geopolymer cement compositions and methods of use

Methods and compositions for cementing operations that include pumice in geopolymer cement compositions comprising slag.

Of the many compositions and methods provided herein, one method includes providing a settable fluid that comprises an aqueous-based medium, a lime composition, and a cementitious blend that comprises metakaolin particulates and aluminosilicate particulates, wherein the cementitious blend is essentially free of Portland cement; introducing the settable fluid into a wellbore penetrating a subterranean formation that comprises a corrosive component; and allowing the settable fluid to set therein.

Settable compositions containing metakaolin having reduced portland cement content

Methods and compositions are provided that relate to cementing operations, including a method of cementing that may comprise providing a settable composition that may comprise wollastonite, pumice, a calcium-ion source, and water, wherein the wollastonite may be present in an amount in a range of from about 25% to about 75% by combined weight of the wollastonite and pumice, and wherein the pumice may present in an amount in a range of from about 25% to about 75% by combined weight of the wollastonite and pumice. Embodiments of the method further may comprise allowing the settable composition to set.

Settable compositions comprising wollastonite and pumice and methods of use

A method of servicing a wellbore comprising preparing a composition comprising a calcium aluminate cement, water, a polyphosphate, a pozzolan, and a set retarding agent, wherein the set retarding agent comprises an alkali halide and a basic phosphate salt, placing the composition in the wellbore and allowing the composition to set. A composition comprising a calcium aluminate cement in an amount of from about 30 wt. % to about 60 wt. % and a set retarding agent in an amount of from about 0.1 wt. % to about 15 wt. % based upon the total weight of the composition, wherein the set retarding agent comprises an alkali halide and a basic phosphate salt in a ratio of from about 3:1 to about 1:3.
