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.

摘要： Methods of fracturing a subterranean formation include providing a fracturing fluid having a first pH. The fracturing fluid may be made by combining a gelling agent, a surfactant, and a proppant. The surfactant is capable of facilitating foaming of the fracturing fluid at the first pH and defoaming of the fracturing fluid when its pH is changed to a second pH. The methods of fracturing the subterranean formation further include foaming the fracturing fluid having the first pH and subsequently pumping it to the subterranean formation to fracture the formation. The pH of the fracturing fluid changes to a second pH, for example via in situ contact with an acidic material, causing the level of foam in the fracturing fluid to be reduced. As a result of the reduction of the foam, the fracturing fluid deposits the proppant into the fractures formed in the subterranean formation.

摘要： A portable breakwater system for use in a body of water includes first and second support members adapted to be positioned on the floor of the body of water and a curtain attached between the first and second support members. The first and second support members allow the curtain to freely rise in response to a wave in the body of water so as to attenuate the wave. Each support member includes a base plate and a frame assembly extending upwardly from the base plate. The base plates can be anchored to the water floor with one or more weights. The frame assemblies include pivoting or telescoping sections that permit the curtain to rise in response to a wave. Alternatively, the curtain can be attached to pre-existing underwater structure, such as the support members of a dock located in the body of water. In this case, the curtain is attached to the support members via attachment sleeves that are slidingly mounted on the support members.
