    摘要: An environmentally-friendly cleaning composition for oil cleaning comprising (a) a blend of dibasic esters, (b) one or more surfactants (c) and, optionally, (d) water or a solvent. The dibasic esters are be derived from a blend of adipic, glutaric, and succinic diacids, and, in one particular embodiment, the blend comprises dialkyl adipate, dialkyl methylglutarate and dialkyl ethylsuccinate, wherein the alkyl groups individually comprise a C1-C12 hydrocarbon group. The one or more surfactants are typically chosen from alcohol alkoxylate, an alkyl phenol ethoxylate, a terpene, a terpene alkoxylate or any derivates thereof. Optionally, additional components or additives including delaminates such as pinene and d-limonene, fragrances, whiteners, stabilizers, thickeners and the like can be added to the composition.

    摘要: There is a method for enhancing the recovery of oil from a reservoir. The method has the step of a) introducing a flooding fluid into the reservoir and b) extracting the oil through a wellbore at a location different than the point of introduction of the flooding fluid into the reservoir. The flooding fluid has water and an amount of one or more non-polymeric viscoelastic surfactants sufficient to provide an interfacial surface tension of about 1 mNm or less and a viscosity of about 10 cps or more. The one or more surfactants is selected from the group of one or more cationic surfactants, one or more zwitterionic surfactants, one or more amphoteric surfactants, one or more anionic surfactants, and combinations thereof.

    摘要: A temperature-stable, non eco-toxic oil-base well fluid that is particularly suitable for high pressure/high temperature drilling comprises an emulsification system comprising at least one superamide that may or may not be polyalkoxylated, optionally associated with a non-ionic co-surfactant. The oil-base well fluid comprising such a system can be used at temperatures of up to about 200° C. due to the production of highly temperature-stable reverse emulsions.
