Abstract
One embodiment provides a method for stimulating hydrocarbon production in a subterranean formation, comprising: introducing a peroxide-generating compound into a desired location in a subterranean formation, wherein the peroxide-generating compound is substantially mechanically isolated from the subterranean formation until the peroxide-generating compound reaches the desired location; and allowing the peroxide-generating compound to generate peroxide in the desired location in the subterranean formation. Another embodiment provides a method for stimulating hydrocarbon production in a subterranean formation, comprising: introducing a peroxide-generating compound into a desired location in a subterranean formation, wherein the peroxide-generating compound further comprises a chemical moderator that acts to inhibit the reaction of the hydrogen peroxide within the subterranean formation; and later, allowing the peroxide-generating compound to generate peroxide in the desired location in the subterranean formation. Another embodiment provides a treatment fluid for stimulating hydrocarbon production from a subterranean formation, comprising peroxide-generating compound and a moderator.
