    摘要： Methods including providing at least one target interval in a wellbore, wherein the at least one target interval has a temperature of at least about 70°F to at least about 290°F; providing a pad fluid; providing a treatment fluid comprising proppant particulates coated with a one-step furan resin composition, wherein the one-step furan resin composition comprises a furan polymer, a hydrolyzable ester, a silane coupling agent, a surfactant, and a solvent; introducing the pad fluid into the wellbore at a rate and pressure sufficient to create or enhance at least one fracture within the target interval; introducing the treatment fluid into the wellbore so as to deposit the proppant particulates coated with the one-step furan resin composition into the at least one fracture; and setting the one-step furan resin composition so as to form at least a partially consolidated permeable proppant pack in the at least one fracture.

    摘要： A composition for treating a portion of a wellbore or a portion of a subterranean formation is provided, the composition comprising: (a) water; (b) a source of hydrogen peroxide, and (c) an activator for the source of hydrogen peroxide; wherein the pH of the composition is adjusted to be within an appropriate range for the type of activator. A method for treating a portion of a wellbore or a portion of a subterranean formation, the method comprising the steps of: forming or providing a composition comprising: (a) water; (b) a source of hydrogen peroxide, and (c) an activator for the source of hydrogen peroxide; wherein the pH of the composition is adjusted within an appropriate range for the type of activator; and introducing the composition through a wellbore to treat a portion of a wellbore or a portion of a subterranean formation. The activator can be a water-soluble alkanoyl-donor compound or a chelated transition metal. The method has particular applications where the static temperature of the portion of the wellbore or the portion of the subterranean formation to be treated is less than 1000F (38°C).
