Abstract: 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.

Abstract: 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).
Abstract: A method of drilling or gas-lifting is disclosed where the methods including the use of a foaming agent and a gas, where the foaming agent is a keratin and the hydrostatic pressure of the fluid in the well is for a portion of the drilling or gas-lift operation less than an hydrostatic pressure of the formation being drilled or under production.
