Patent ID: 7932216

Claim:
A liquid non-phosphorus gellant for gelling a fracturing fluid comprising: one or more asymmetrical liquid reaction products resulting from the reaction of oxoaluminum acylate; isopropyl hexanoate ester; and a fatty acid having from about C 6 to about C 18 and 2-ethylhexanoic acid; and an effective amount of a rheology modifier sufficient to preferentially interact with the one or more reaction products for preventing interaction between the one or more reaction products so as to prevent solidifying of the one or more reaction products until such times as the liquid gellant is mixed in the fracturing fluid in which an activator is present: wherein the one or more liquid reaction products are a mixture of an aluminum di-2-ethyl hexanoate-fatty acid ester complex and hydroxyl aluminum di-2-ethyl hexanoate; and the gellant gels the fracturing fluid in less than 30 seconds.
