摘要： Hydrolyzed nitrilotriacetonitrile compositions are disclosed prepared by a method characterized by a one-shot addition of an amount of nitrilotriacetonitrile to a solution containing an acid catalyst, where the reaction is complete in a time period of less than an hour. The method is also characterized by adjusting the pH of the reaction mixture to a pH of at least 8. The method is also characterized by oxidatively removing free cyanide to a desired low level through the addition of an oxidizing agent the produces environmentally benign by-products to the crude hydrolyzed NTAN to form hydrolyzed NTAN compositions having minimized, negligible, or substantially no free cyanide levels.

摘要： Coacervate gels having excellent shear viscosities and other properties are made with anionic or cationic polymers, a smaller amount of a surfactant having a charge opposite that of the polymer, and a hydrophobic alcohol and an effective amount of a phosphorus-containing compound sufficient to increase the viscosity of coacervate gels up to 3 times as compared to the gels in the absence of the phosphorus-containing compound. The Zeta Potential of the gel is maintained at an absolute value of at least 20. Optional gel promoting additives include betaines and amine oxides. A preferred gel comprises poly diallyl dimethyl ammonium chloride, a lesser amount of sodium lauryl sulfonate, and lauryl alcohol. The gels are particularly useful in well drilling fluids and well fracturing fluids.

摘要： A system and method for cavitating a producible formation is disclosed to improve hydrocarbon production and to increase a production rate without an concurrent co-production of formation particulate. The method and system include conglomerating the producible formation using a conglomerating composition. Once the producible formation is conglomerated, the conglomerated, producible formation is produced above its critical draw down pressure to form a cavity surrounding the wellborn in the conglomerated, producible formation and placing the cavitated, conglomerated, producible formation on production below a higher maximum sand free rate (MSFR).
