摘要： Methods comprising: providing an aqueous treatment fluid comprising an aqueous fluid, a friction reducing polymer, and an antiflocculation additive; and introducing the treatment fluid into a subterranean formation. Methods of fracturing a subterranean formation comprising: providing an aqueous treatment fluid comprising an aqueous fluid, a friction reducing polymer, and an antiflocculation additive; and introducing the treatment fluid into a well bore penetrating the subterranean formation at rate in the range of from about 30 barrels to about 250 barrels per minute so as to create or enhance one or more fractures in the subterranean formation. Aqueous treatment fluids comprising: an aqueous fluid, a friction reducing polymer in an amount sufficient to reduce friction without forming a gel, and an antiflocculation additive.

摘要： One embodiment of the present invention provides methods of treating a portion of a subterranean formation, comprising providing a treatment fluid comprising a derivatized cellulose gelling agent wherein the derivatized cellulose gelling agent is made by reacting cellulose with an electrophilic agent to form a 1,3-cis diol or an alpha carboxylic acid; and, placing the treatment fluid in the portion of the subterranean formation. Another embodiment of the present invention provides methods of derivatizing cellulose, comprising reacting cellulose with an electrophilic agent to form a 1,3-cis diol or an alpha carboxylic acid. Another embodiment of the present invention provides crosslinkable treatment fluids for use in subterranean formations comprising a derivatized cellulose gelling agent wherein the derivatized cellulose gelling agent comprises a cellulose that has been derivatized to comprise an alpha carboxylic acid or a compound comprising a 1,3-cis diol moiety.
