摘要： Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities reduced (gels broken) by the direct or indirect action of a composition that contains at least one metal ion source and optionally at least one second source. An optional second source may be a chelating agent where at least one reducing agent source may be additionally optionally used. Another optional component with the metal ion source includes a second, different metal ion source. The breaking composition is believed to directly attack the VES itself, possibly by disaggregating or otherwise attacking the micellar structure of the VES-gelled fluid, and/or possibly by changing the chemical structure of the VES to give two or more products.
摘要翻译：用粘弹性表面活性剂（VES）增稠的流体可以通过包含至少一种金属离子源和任选的至少一种第二来源的组合物的直接或间接作用使其粘度降低（凝胶破裂）。任选的第二来源可以是其中可以另外任选使用至少一种还原剂源的螯合剂。具有金属离子源的另一选择性组分包括第二种不同的金属离子源。相信断裂组合物可能直接攻击VES本身，可能是通过解散或以其他方式攻击VES凝胶化流体的胶束结构，和/或可能通过改变VES的化学结构以给出两种或多种产品。

摘要： The present invention generally relates to aqueous, acidic compositions thickened with an amidoamine oxide gelling agent and/or viscoelastic surfactant of the general formula (I) wherein R1 is a saturated or unsaturated, straight or branched chain aliphatic group of from about 7 to about 30 carbon atoms, R2 is a divalent alkylene group of 2-6 carbon atoms which may be linear or branched, substituted or unsubstituted, and R3 and R4 are independently C1-C4 alkyl or hydroxyalkyl groups or together they form a heterocyclic ring of up to six members, and R5 is hydrogen or a C1-C4 alkyl or hydroxyalkyl group. The aforementioned gelling agents advantageously provide gels that do not undergo phase separation over extended periods of time and exhibit high heat stability. The Thickened acid gels of the invention have applications in household and industrial cleaners and degreasers, oilfield stimulation applications and the like.

摘要： Viscoelastic surfactant fluids for fracturing subterranean formations penetrated by a well bore. The surfactant fluids are comprised of an aqueous medium; an effective amount of an inorganic water soluble salt; and an effective amount of at least one surfactant selected from the group consisting of: i) anionic surfactants; ii) nonionic surfactants; and iii) hydrotropic surfactants. The surfactant compositions can be further stabilized and the viscosity increased by the addition of one or more hydrophobic organic alcohols. This invention also relates to a method for fracturing subterranean formations using said viscoelastic surfactant fluids.

摘要： The improved recovery of hydrocarbons from subterranean formations by hydraulically fracturing a subterranean formation is accomplished. Fracturing fluids using a viscoelastic surfactant fluid containing wormlike micelles are useful to improve recovery of hydrocarbons and limit the loss of fracturing fluid into the formation fracture face. The invention further relates to novel fracturing methods useful for increasing hydrocarbon production, limiting connate water production, resisting fracturing fluid loss into the subterranean formation, and reducing the equipment requirements in mixing and pumping fracturing fluid. The action of micelles of surfactant in aqueous zones of the subterranean formation facilitates the flowback of increased amounts of hydrocarbons once a fractured well is placed back on production.
