摘要： A method of treating a subterranean formation penetrated by a wellbore utilizes a treating fluid formed from an aqueous solution of a water-soluble polymer. The treating fluid further contains a crosslinking agent and an optional delayed release alkaline additive. The delayed release alkaline additive may be at least one of urea, a urea derivative, a solid alkaline earth metal carbonate, a solid alkaline earth metal oxide and combinations of these. The treating fluid further includes an acidic pH adjusting agent used in an amount to provide the treating fluid with a pH of less than about 5. The treating fluid is then introduced into the formation.

摘要： Xanthan molecules are degraded using a xanthanase enzyme complex that is stable at temperatures above 250 DEG F, such as those temperatures found in some wellbores and process streams. The xanthanase enzyme complex is produced by a novel soil bacterium. The xanthanase enzyme complex may be used to remove xanthan based formation damage, such as drilling filter-cakes and filtrates, or to remove xanthan based filter-cakes and/or residues present in processing equipment. The xanthanase enyzme complex may also be used to reduce the viscosity of xanthan-containing fluids, such as hydraulic fracturing fluids, blocking gels, drilling muds, and process fluids. The xanthanase enzyme complex may also be used in conjunction with other well or process treatments, such as stimulations and cementing operations, to improve the effectiveness of these treatments.
摘要翻译：黄原胶分子使用在高于250°F的温度下稳定的镧系元素复合物进行降解，例如在一些井筒和工艺流中发现的那些温度。镧系元素复合物由新型土壤细菌产生。黄原胶酶复合物可用于去除基于黄原胶的地层破坏，例如钻孔滤饼和滤液，或去除加工设备中存在的黄原胶滤饼和/或残留物。还可以使用镧系元素络合物来降低含黄原胶的流体，例如水力压裂液，阻塞凝胶，钻井泥浆和工艺流体的粘度。黄原酸酶复合物也可以与其它井或工艺处理如刺激和固井操作一起使用，以提高这些处理的有效性。
