Abstract: A method of treating a subterranean formation, for example a subterranean formation susceptible to formation of a undesirable gel-like goo, is described. The method comprises contacting the formation with a fluid (A) comprising a polymer (PP) which includes a pendent group which includes a moiety O—S?O??(I) wherein the sulphur atom of the moiety is covalently bonded, optionally via a linking atom or group, to the backbone of the polymer.

Abstract: The embodiments herein relate generally to subterranean formation operations and, more particularly, to surfactant flowback aids for use in subterranean formation operations. The surfactant flowback aid composition may comprise an aqueous phase comprising an aqueous base fluid, a surfactant blend, and a demulsifier. The surfactant blend may comprise a C8-C18 alcohol ethoxy-late; a fatty acid alkanolamide; and optionally, a surfactant selected from the group consisting of a non-ionic surfactant, an anionic surfactant, a cationic surfactant, an amphoteric surfactant, and any combination thereof. The demulsifier may be selected from the group consisting of a desalter agent to separate water from crude oil, a treater agent to flocculate submicron particulates from crude oil, and any combination thereof.

Abstract: Methods and systems for treating a subterra-nean formation. An example method comprises pumping an aerosol comprising a vaporized carrier fluid and a dispersed polyhydroxyetheramine in a wellbore penetrating the sub-terranean formation; depositing the polyhydroxyetheramine on a surface of the subterranean formation; and producing hydrocarbons from the treated subterranean formation.

Abstract: Spectroscopic analyses of complex mixtures within the matrix of a sample can oftentimes be complicated by spectral overlap of the constituents and/or the matrix, making it difficult to quantitatively assay each constituent therein. Methods for analyzing a sample can comprise: providing a sample comprising a matrix and one or more constituents therein; exposing the sample to electromagnetic radiation in a spectral region where the matrix optically interacts with the electromagnetic radiation, so as to acquire a spectrum of the matrix; and analyzing the spectrum of the matrix within a wavelength range where the matrix has a molar extinction coefficient of at least about 0.01 M?1mm?1 to determine at least one property of the sample, the at least one property of the sample being selected from the group consisting of a concentration of at least one constituent in the sample, at least one characteristic of the sample, and any combination thereof.

Abstract: Spectroscopic analyses of complex mixtures within a fluid phase can oftentimes be complicated by spectral overlap, making it difficult to analyze for each constituent therein. Methods for analyzing a treatment fluid can comprise: providing a treatment fluid comprising a fluid phase and one or more constituents therein; exposing the treatment fluid to electromagnetic radiation in a spectral region where the fluid phase optically interacts with the electromagnetic radiation, so as to acquire a spectrum of the fluid phase; analyzing the spectrum of the fluid phase to determine at least one property of the treatment fluid, the at least one property of the treatment fluid being selected from the group consisting of a concentration of at least one constituent in the treatment fluid, at least one characteristic of the treatment fluid, and any combination thereof; and introducing the treatment fluid into a subterranean formation.
