Abstract: Compositions, methods, and resins using alkyl aldehydes and phenols are provided herein. In one embodiment, a composition comprising an alkylphenol resin can be prepared by condensing at least one phenolic monomer selected from the group consisting of phenol, cresol, resorcinol, xylenol, ethyl phenol, alkylresorcinols, and combinations thereof; and at least one alkyl aldehyde having from 5 to 12 carbon atom alkyl groups. The alkylphenol resins of the application are free of octylphenol or nonylphenol monomers. In one embodiment, the alkylphenol resins may be prepared using formaldehyde, and alternatively, in another embodiment, the alkylphenol resins may be prepared without the use of formaldehyde. The process to make these new alternative alkylphenol resins is a cost effective process and easy to scale-up.

Abstract: Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.

Abstract: Dust produced by handling proppant during fracking or other mechanical operations can be a health and/or safety hazard. The dust can be eliminated or at least mitigated using a method of conducting a hydraulic fracturing or other mechanical operation on an oil or gas well including treating a proppant that has been transported to an end use site at a level sufficient to prevent the formation of dust during handling of the proppant.

Abstract: A method of making a proppant-gel matrix comprising: a) hydrating a gelling agent to form a hydrated gelling agent; b) adding a basic compound to the hydrated gelling agent to form a basic hydrated gelling agent having a pH in the range of 11.5 to 14.0; c) mixing the basic hydrated gelling agent and a proppant to form a basic hydrated gelling system; and d) adding a crosslinking agent to the basic hydrated gelling system to form the proppant-gel matrix, is disclosed. The proppant-gel matrix can then be used as a fracturing fluid in a hydraulic fracturing process.
