Abstract: Methods herein may include injecting a cement slurry having an aqueous base fluid, a cement, and a plurality of cellulose nanofibers dispersed in the aqueous base fluid. The plurality of cellulose nanofibers may be present in the slurry in an amount effective to provide a slurry density of not higher than 15 lb/gal.

IPC: C09K8/467
CPC classification number: C09K8/467
Abstract: Geopolymer precursor compositions are presented that are useful for cementing a subterranean well, among other uses. The precursor compositions are dry mixtures that have an aluminosilicate source and an activator. The activator is an alkalinity source that is safe to store, transport, and blend with an aluminosilicate source. The activator may be a hydroxide-free activator. A geopolymer slurry is formed by adding water to the dry geopolymer precursor compositions. Such slurries have suitable characteristics for use in cementing applications that use pumpable mixtures.

Abstract: Described herein are methods for on the fly mixing of retarded acidizing fluids containing acid, a water-soluble acid retarding agent (RA), and optionally a viscoelastic surfactant (VES), and for on the fly mixing of diversion fluids containing VES and RA in the same equipment. Also described are methods of controlling the preparation of such fluids based on feedback composition analyses.

Abstract: A method is provided for treating at least a portion of a subterranean formation. The method includes introducing a treatment fluid including a composite particle, which includes proppant incorporated into or attached to a swellable material and/or swellable materials, into a subterranean formation via a wellbore; and increasing the buoyancy of the composite particle including proppant by either mixing it with a treatment fluid or mixing it with a treatment fluid and triggering the swellable material and/or swellable materials to swell.
