Abstract: A dry, free-flowing cement composition that comprises dry cement particles and flow inducing particulates that comprise solid adsorbent particulates having adsorbed thereon a flow inducing chemical, ethylene glycol, and water. The water is present in an amount from 5% to 30.3% by weight of the solid adsorbent particulates, the ethylene glycol is present in an amount from 3.25 to 20% by weight of the solid adsorbent particulates, and the flow inducing particulate is present in an amount from 0.005% to 5% by weight of the cement. The dry, free-flowing cement composition is free-flowing at temperatures at least as low as 10° F.

Abstract: Compositions that may improve the flow properties of dry particulate cementitious and non-cementitious materials, and methods of synthesis and use, are provided. In one embodiment, the methods may comprise providing a flow enhancing additive comprising a flow inducing chemical, a solid adsorbent particulate material, ethylene glycol, and water; providing a cementitious material, a non-cementitious material, or a mixture of cementitious and non-cementitious material; and blending the flow enhancing additive with the cementitious material, the non-cementitious material, or the mixture of cementitious and non-cementitious material.

Abstract: Solid, flowable compositions comprising a dry, solid particulate material and a flow enhancing additive. The dry, solid particulate material may be cementitious, non-cementitious material, or a combination thereof. The flow enhancing additive comprises a solid, particulate absorbent material having absorbed thereon: a flow inducing chemical, ethylene glycol, and water. In some cases the flow inducing chemical comprises an organic acid, a salt of an organic acid, an acid anhydride, or a combination thereof.

Abstract: Methods comprising providing a dry, solid particulate material comprising a cementitious material, a non-cementitious material, or a combination thereof and having a flow enhancing additive absorbed thereon. The flow enhancing additive comprises a flow inducing chemical, ethylene glycol, and water. The coated, dry, solid material is then mixed with a sufficient amount of water to form a pumpable slurry and then the slurry may be placed in a subterranean formation. In some cases the dry, solid particulate material comprising a cementitious material, a non-cementitious material, or a combination thereof and having a flow enhancing additive absorbed thereon may be stored for a period of time before the slurry is formed.

Abstract: According to various embodiments, methods of increasing a shelf life of a gas-generating material comprise: including a C8-C18 hydrocarbon in a mixture used to coat the gas-generating material. This gas-generating material may be used in a cement composition to generate gas therein after the composition has been placed in a wellbore. The coating surrounding the gas-generating material serves to delay the reaction for producing the gas until desired. The gas may serve to inhibit gas migration from an adjacent subterranean formation into and through the cement composition before it sets into a hard mass. Coating the gas-generating material with the mixture may ensure that it can be stored for a relatively long period of time (e.g., up to 1 year or longer) without being concerned that it might experience sintering and thus react prematurely.

Abstract: According to various embodiments, gas-generating additives for use in a cement composition comprise: a gas-generating material at least partially coated with a mixture comprising a fatty acid ester of sorbitan, glycerol, or pentaerythritol and having a shelf life of about 12 months or greater. The gas-generating additives may also include a C8-C18 hydrocarbon. In more embodiments, cement compositions comprise: a gas-generating material at least partially coated with a mixture comprising a fatty acid ester of sorbitan, glycerol, or pentaerythritol and a C8-C18 hydrocarbon for increasing a shelf life of the gas-generating material. In yet more embodiments, cement compositions comprise: a cement; a fluid for making the cement composition pumpable; a hydrogen-generating material at least partially coated with a mixture for delaying a hydrogen-generating reaction, the mixture comprising sorbitan monooleate and an isoparaffin.
