Abstract

A fracturing fluid composition is described for use in fracturing low temperature underground formations, such as oil or gas wells. It includes at least one anhydrous aliphatic alcohol, a modified guar gum polymer, and as a complexor, a sodium perborate salt. A gel breaker is also provided, including sodium perborate which acts over a time period to degrade the guar gum cross linked polymer and thereby reduce the viscosity of the gel, to aid in the removal thereof from a well.
