may be pre blended together prior to being added to the fracturing fluid generally suitable degradable particulates used in the present invention are formed of materials capable of undergoing an irreversible degradation down hole as referred to herein the term u201c irreversible u201d will be understood to mean that the degradable material once degraded down hole should not reconstitute while down hole e g the degradable material should degrade in situ but should not reconstitute in situ the terms u201c degradation u201d and u201c degradable u201d refer to oxidative degradation hydrolytic degradation enzymatic degradation or thermal degradation that the degradable material may undergo in hydrolytic degradation the degradable particulate degrades or dissolves when exposed to water non limiting examples of degradable materials that may be used in conjunction with the present invention include but are not limited to aromatic polyesters and aliphatic polyesters such polyesters may be linear graft branched crosslinked block star shaped dendritic etc some suitable polyesters include poly hydroxy alkanoate pha poly alpha hydroxy acids such as polylactic acid pla polygylcolic acid pga polylactide and polyglycolide poly beta hydroxy alkanoates such as poly beta hydroxy butyrate phb and poly beta hydroxybutyrates co beta hydroxyvelerate phbv poly omega hydroxy alkanoates such as poly beta propiolactone ppl and poly u03b5 caprolactone pcl poly alkylene dicarboxylates such as poly ethylene succinate pes poly butylene succinate pbs and poly butylene succinate co butylene adipate polyanhydrides such as poly adipic anhydride poly orthoesters polycarbonates such as poly trimethylene carbonate and poly dioxepan 2 one derivatives of the above materials may also be suitable in particular.
