A method includes introducing a cementing composition into a subterranean formation, the cementing composition including a pumpable slurry of cement including an epoxy resin, an epoxy resin hardening agent, and a compatibilizer, where the compatibilizer is a lignite grafted copolymer; and allowing at least a portion of the cementing composition to harden. A composition includes a pumpable slurry of cement including an epoxy resin, an epoxy resin hardening agent, and a compatibilizer, where the compatibilizer is a lignite grafted copolymer.

Additive for improving homogeneity of epoxy resin and cement composites

A cement composition for use in a well that penetrates a subterranean formation comprising: cement; water; and an additive comprising zirconium dioxide, wherein at least a portion of the zirconium dioxide is in a metastable tetragonal phase, and wherein some or all of the zirconium dioxide that is in the metastable tetragonal phase transforms to a stable monoclinic phase after a stress is applied to the cement composition. The additive also reduces the dimensions of a crack located within the set cement composition. A method of cementing in a subterranean formation comprising: introducing a cement composition into the subterranean formation.

Crack-resistant cement composition

Methods of inhibiting corrosion of metal surfaces by aqueous acids are described. The methods include combining an effective amount of a corrosion inhibitor composition with an aqueous acid solution to form an inhibited acid solution and contacting a metal surface with the inhibited acid solution. The corrosion inhibitor composition includes an aromatic ketone or a salt thereof.

Environmentally friendly corrosion inhibitors for high temperature applications

A cement composition and method for well treatment employing the cement composition that is effective at achieving zonal isolation, controlling gas migration, preventing corrosive conditions and sustaining wellbore integrity during drilling or construction of boreholes in such subterranean formations. The cement composition includes spent cracking catalyst from oil cracking processes.

Methods of cementing and spent cracking catalyst-containing cement

Olefins are produced by the reductive dehydroxylation of vicinal polyols or esters thereof, or a combination thereof, in a liquid reaction medium, under a hydrogen atmosphere, at a temperature from 50&#xb0; C. to 250&#xb0; C., in the presence of a halogen-based, preferably iodine-based, catalyst. Examples of the catalyst, which may be included independently or generated in situ, are iodine (I), hydroiodic acid (HI), iodic acid (HIO), lithium iodide (LiI), and combinations thereof.

Iodine-based catalyst for reductive dehydroxylation of vicinal polyols to olefins

Olefins may be produced by the reductive dehydroxylation of vicinal polyols and/or their respective esters, in an aqueous reaction medium, under a hydrogen atmosphere, under suitable conditions, and in the presence of a halogen-based, preferably iodine-based, catalyst, wherein a solubility enhancing agent is employed to increase the solubility of the iodine-based catalyst in the aqueous reaction medium.

Reductive dehydroxylation of vicinal polyols to olefins using an iodine-based catalyst having enhanced solubility

Crude alcohol streams are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. The process includes autogenous gas pressure or a gas pressure from 1 psig (&#x2dc;6.89 KPa) to 2000 psig (&#x2dc;13.79 MPa), a temperature from 50&#xb0; C. to 250&#xb0; C., a liquid reaction medium, and a molar ratio of alcohol to halogen from 1:10 to 100:1.

Dehydroxylation of crude alcohol streams using a halogen-based catalyst

Olefins may be produced by the non-reductive dehydroxylation of vicinal polyols and/or their respective esters, in a liquid reaction medium, under a substantially non-reductive atmosphere, in the presence of a halogen-based, preferably iodine-based, catalyst. The reaction medium may be aqueous, non-aqueous, or a combination thereof, and may in some embodiments include a solubility enhancing agent.

Non-reductive dehydroxylation of vicinal compounds to olefins using a halogen-based catalyst
