    摘要： Disclosed is an alkaline earth metal peroxide concentrate, or fluidized suspension, for addition to aqueous hydraulic fracturing fluids to efficiently decrease the viscosity of the hydrated, hydrophilic polysaccharide polymer in the system. The concentrate comprises a hydrophobic, water insoluble liquid, an organophilic clay suspension agent, a polar activator, a sparingly-soluble alkaline earth metal peroxide, and an anionic surfactant. Advantageously, these concentrations, or suspensions, exhibit high flash points, making them easier to transport using commercial transportation means.

    摘要： The invention pertains to a process for fracturing a subterranean formation using a mixture of methane (natural gas) and propane/butane (liquefied petroleum gas). The process comprises: a)providing a first fluid (in a gas or liquefied form) comprising at least 50 wt.% of methane: b)providing a second fluid (in a gas or liquefied form) comprising at least 50 wt.% of the combination of propane and butane: c)mixing and, in case of a gas mixture, liquefying said first fluid and said second fluid to obtain a liquefied fluid mixture comprising 15-80 wt.% of methane and 15-80 wt.% of the combination of propane and butane, said liquefied mixture having a temperature and a pressure such that the liquefied fluid stays above the bubble point of the mixture; d)blending a proppant and/or a gellant into the liquefied fluid mixture to produce a 1 fracturing fluid; e)injecting the fracturing fluid into the subterranean formation.
