    摘要: A treatment fluid for treating a subterranean formation penetrated by a wellbore is formed from water, a polyacrylamide in an amount of less than about 0.5% by weight of the fluid for reducing friction of the fluid and a stabilized peroxide breaker. A method of treating a subterranean formation penetrated by a wellbore is carried out by forming treatment fluid comprising water, a polyacrylamide in an amount of less than about 0.5% by weight of the fluid for reducing friction of the fluid and a stabilized peroxide breaker. The treatment fluid is introduced into the formation through the wellbore at a pressure above the fracture pressure of the formation.

    摘要: The invention provides a method. The method injects into a wellbore, a fluid comprising at least one of an acrylamide polymer and an acrylamide copolymer, and at least one of an oxidizing agent and a radical initiator; and allows viscosity of the fluid to increase for a first period of time; and subsequently, allows viscosity of the fluid to decrease for a second period of time. In a further aspect the invention provides a fluid for use in a well within a subterranean formation penetrated by a wellbore. The fluid is in a first embodiment, made of an acrylamide polymer and/or copolymer and an oxidizing agent or radical initiator, wherein concentration of the oxidizing agent or radical initiator is such that the fluid increases its viscosity for a period of time and after said period of time decreases its viscosity. The fluid is in a second embodiment, made of an acrylamide polymer and/or copolymer and an oxidizing agent or radical initiator, wherein the oxidizing agent or radical initiator is such that the fluid increases its viscosity for a period of time and after said period of time decreases its viscosity.

    摘要: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Acidic internal breakers such as sulfuric acid and nitric acid are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger.

    摘要: Internal breakers are given that break fluids viscosified with non-polymeric viscosifiers such as viscoelastic surfactants, inside formation pores. The breakers are polyols, for example natural and synthetic sugars, monoalcohols, and mixtures of the two. The sugars may be ketones and aldehydes. The sugars are also breaker aides for oxidizing agents used as breakers. Methods of using the breakers and breaker aides in oilfield treatment fluids are given.
