摘要： Embodiments relate to improving the performance of anionic friction reducing polymers in water containing multivalent ions. Exemplary embodiments relate to methods of improving the performance of anionic friction reducing polymers in a subterranean treatment, wherein the method comprises adding a complexing agent to water comprising multivalent ions. The method comprises adding the anionic friction reducing polymer to the water comprising the multivalent ions, wherein the anionic friction reducing polymer is added in an amount less than or equal to about 0.15% by weight of the water. The method comprises introducing the water comprising the multivalent ions, the complexing agent and the anionic friction reducing polymer into at least a portion of the subterranean formation such that the friction reducing polymer reduces energy loss due to turbulence in the water. The complexing agent complexes with at least a portion of the multivalent ions in the water such that the reduction of energy loss by the friction reducing polymer is improved.

摘要： Fracturing fluids and methods of fracturing a subterranean formation using such fluids are provided. A fracturing fluid having a first pH is foamed by introducing a gas to the fluid. The fracturing fluid comprises a surfactant that facilitates formation of the foam at the first pH. The foamed fracturing fluid is subsequently pumped to the subterranean formation to fracture it. The pH of the fracturing fluid is then changed to a second pH at which the surfactant facilitates reduction of the foam. The fracturing fluid releases proppant contained in the fluid to the subterranean formation. The fracturing fluid is then allowed to flow back to the surface. It can be recycled by changing the pH of the fracturing fluid back to the first pH and adding a gas to the fluid, causing it to foam again.
