Gelling system for hydrocarbon fluids

摘要

The present invention relates to a gelled hydrocarbon fluid useful as a fracturing fluid in subterranean formations comprising at least one gelling agent which is a salt of a carboxylic acid having from about 6 to about 30 carbon atoms. An activator which is a difunctional and/or trifunctional carboxylic acid is preferably added to control gel time.
