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： It has been discovered that certain fracturing fluid compositions can be used to fracture a subterranean formation and be permitted to stay within the formation for a relatively extended period of time, for example 28 days or more, before being flowed back or produced. At least two embodiments are envisioned, a bacteria-containing formulation and an anti-bacterial formulation. Both systems would be expected to prevent the potential of the fluid to oil wet the formulation (water block condition) by keeping the formation water wet through the use of water wetting surfactants or solvents. Additionally, both formulations would control reservoir crude souring (H2S generation by in situ sulfate-reducing bacteria), reservoir plugging (via slime biopolymers generated by in situ microbes, inorganic scale deposition like calcium carbonate or barium sulfate, and clay fines migration).

摘要： It has been discovered that aminocarboxylic acids are effective breakers for polymer-gelled aqueous fracturing fluids, particularly in the temperature range between about 120° F. (49° C.) and about 280° F. (138° C.). The aminocarboxylic acids are believed to act directly on the polymer and not to any great extent or not to as an effective extent on a crosslinking agent, if present. The polymer may be a polysaccharide, and the aminocarboxylic acid may be selected from the group including, but not necessarily limited to, tetrasodium ethylenediaminetetraacetic acid (Na4EDTA), tetrasodium propylenediaminetetraacetic acid (Na4PDTA), trisodium hydroxyethylenediaminetetraacetic acid (Na4HEDTA), trisodium nitrilotriacetic acid (Na3NTA), salts of these acids, and mixtures thereof.
摘要翻译：已经发现，氨基羧酸是聚合物胶凝水性压裂液的有效断裂剂，特别是在约120°F（49℃）和约280°F（138℃）之间的温度范围内。据信氨基羧酸直接作用于聚合物上，而不会在很大程度上起作用，或作为交联剂（如果有的话）作为有效程度。聚合物可以是多糖，并且氨基羧酸可以选自包括但不一定限于乙二胺四乙酸四钠（钠四钠），丙二胺四乙酸四钠（Na 4） PDTA），三羟乙基二氨基四乙酸三钠（Na 4 HEDTA），次氮基三乙酸钠（N 3 NTA），这些酸的盐及其混合物。
