摘要： The present invention related to a method for fracturing subterranean formations including the steps of (a) providing a water source; (b) adding a crosslinking agent to said water source; (c) adding a polymeric component to said water to create a fracturing fluid; (d) pumping said fracturing fluid into said formation. The fluid may contain an acrylamide-acrylate copolymer and any suitable number of additives. The additives are preferably combined with the water source to form an additive stream, to which the polymer is later added.

摘要： A treatment process for an aqueous phase which contains oil droplets, possibly of 10-50 nm diameter, in aqueous flow from a hydrocyclone separator, comprises bringing the water into contact with a surface subdivided into areas of differing surface energy and affinity for oil and such that when the surface is submerged in an aqueous phase, oil droplets adhere to it with an apparent contact angle in a range from 90 to 150 degrees. Areas of the surface may reduce their affinity for oil in response to an external stimulus causing controlled release of droplets adhering to the surface. The process may be used to remove oil droplets from water produced by an oil or gas well, after downhole oil water separation or after production at a at a well head, or used to coalesce droplets in such water to a larger size to enable conventional separation.
摘要翻译：含水相的处理方法，其水分可能为10-50nm，水力旋流分离器的水流中包括使水与表面细分的表面接触，表面能和对油的亲和性等当表面浸没在水相中时，油滴粘附到其上，其表观接触角在90至150度的范围内。表面的区域可能会降低其对油的亲合力，以响应外部刺激，从而控制释放附着在表面上的液滴。该方法可以用于从油井或气井产生的水中，在井下油水分离之后或在井口产生后除去油滴，或者用于将这种水中的液滴聚结成更大的尺寸以使常规分离。
