    摘要: A method comprises rendering a hydrocarbon industry servicing fluid biologically inert without using chemical biocides. One method of rendering a hydrocarbon industry servicing fluid biologically inert comprises irradiating at least one constituent of the servicing fluid to produce an irradiated fluid. Another method comprises irradiating a used hydrocarbon industry servicing fluid to produce a remediated fluid that is biologically inert. A fluid treatment system comprises an irradiation apparatus, inlet piping directing an untreated fluid into the irradiation apparatus, outlet piping directing an irradiated fluid out of the irradiation apparatus, and a connection to a hydrocarbon industry application.

    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: The present invention relates to a method and system for hydrating a gel for treating a wellbore penetrating a subterranean formation. The method includes directing a base fluid through an inlet into a mixer having an inner chamber housing a plurality of impellers extending radially from and rotating about a hub, causing a centrifugal motion of the base fluid, feeding a quantity of gel into the mixer, mixing the gel with the base fluid and discharging the now-hydrated gel from the inner chamber through an outlet of the mixer. A prewetting device may also be used. Thereafter, a variety of additives may be added to the gel fluid mix to form a fluid treatment to be introduced into a subterranean formation.
