DOWNHOLE TREATMENT COMPOSITIONS COMPRISING LOW TEMPERATURE DEGRADABLE DIVERTING AGENTS AND METHODS OF USE IN DOWNHOLE FORMATIONS

Abstract:

Degradable particulate materials are provided that may be utilized in various wellbore treatment fluids, such as hydraulic fracturing fluids. In particular, the degradable particulate materials can be formed from a cellulosic polymer, a polyester polymer, a polyvinyl alcohol, or a guar gum ester that are capable of effectively degrading at specific rates when exposed to the aqueous environments in low temperature wellbores (50.degree. C. to 100.degree. C.).
