摘要： Disclosed are methods of treating subterranean formations, particularly, treatment methods including preparation of an aqueous treatment fluid composition composed of a carboxy modified polymer, a crosslinking agent, and a viscosifying quaternary amine salt, and subsequently introducing the composition into a the formation to treat. The treatment method is particularly useful for fracturing a subterranean formation. The polymer and crosslinker may be premixed and injected into a wellbore, then mixed therein with the quaternary amine salt to treat the formation. In another aspect, the polymer, crosslinker, and quaternary amine salt are mixed, injected into a wellbore, and introduced in the formation for treatment.

摘要： A hydraulic fracturing method is disclosed that includes designing a fracture treatment including a fluid pumping schedule to fracture a subterranean formation according to a design model that accounts for cumulative filter cake thickness, including polymer concentrated at the fracture surfaces, to provide a propped fracture width effectively greater than the cumulative filter cake thickness, and injecting fluids through a wellbore into the formation essentially according to the fluid pumping schedule of the fracture treatment design. A fracturing method is also disclosed that includes placing a high breaker loading in the filter cake. A composition is disclosed which comprises a fluid viscosified with a polymer and a fluid loss additive comprising a delayed breaker.

摘要： Methods and compositions are disclosed for controlled addition of components that decrease the viscosity of the viscoelastic surfactant fluids or for controlled changes in the electrolyte concentration or composition of the viscoelastic surfactant fluids. One aspect of the invention relates to the use of internal breakers with a delayed activation. Another aspect of the invention relates to the use of precursors that release a breaking system such as alcohol by a process such as melting, slow dissolution, reaction with a compound present in the fluid or added to the fluid during or after the step of injecting, rupture of an encapsulating coating and de-adsorption of a breaking agent absorbed into solid particles. In another aspect of the invention, alcohols are included in a pad to reduce the low-shear viscosity and reduce the resistance to flow of the treatment fluids during a desired phase of the treatment.
