摘要： A method is disclosed that includes adding a recirculation chemical composition to a hydrocarbon containing stream, wherein the recirculation chemical composition may be an emulsion breaker. The method may also include separating the hydrocarbon containing stream into a stream containing water and a stream containing oil; contacting the stream containing oil in a water wash unit; and removing residual emulsion breaker from the stream containing oil.

摘要： Nano-sized mixed metal oxide carriers capable of delivering a well treatment additive for a sustained or extended period of time in the environment of use, methods of making the nanoparticles, and uses thereof are described herein. The nanoparticles can have a formula of:


A/[Mx1My2Mz3]OnHm

where x is 0.03 to 3, y is 0.01 to 0.4, z is 0.01 to 0.4 and n and m are determined by the oxidation states of the other elements, and M1 can be aluminum (Al), gallium (Ga), indium (In), or thallium (Tl). M2 and M3 are not the same and can be a Column 2 metal, Column 14 metal, or a transition metal. A is can be a treatment additive.

摘要： Low-dosage hydrate inhibitor (“LDHI”) compounds comprising multiple lipophilic tails and a hydrophilic head may be employed into fluids to inhibit agglomeration of hydrates, among other things. Suitable hydrophilic heads may include quaternary or tertiary ammonium cation moieties, and combinations thereof. Such LDHI compounds in some embodiments may include reaction products of DETA and/or other amines, fatty acid(s), and, optionally, alkyl halide(s). Compounds according to some embodiments may be employed in fluids in various environments, such as a conduit penetrating a subterranean formation, or a conduit carrying fluid in an industrial setting.
