    摘要: Gel compositions are disclosed including a high molecular weight water-soluble acrylamide polymer, a chromium III/carboxylate complex capable of crosslinking the polymer and a buffered aqueous solvent. The gel compositions are prepared at the surface and injected into a zone of a formation assessable by a wellbore to form a continuous single-phase gel. The gel compositions may be tailored to a specific formation by predetermining gelation rate, gel strength and/or gel stability to form gels having predetermined properties suitable for the zone.

    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.
