    摘要： The present disclosure provides methods for degrading filter cake and filter cake removal, and compositions for removing filter cake from a subterranean borehole. The methods involve contacting the filter cake with a composition containing an unencapsulated peroxygen and a surfactant, and allowing the composition to remain in contact with the filter cake at a temperature above 165°F for a period of time sufficient to degrade the filter cake. The methods result in acidic conditions, thereby eliminating any need for follow up acid treatments. The composition is stable enough to effectively remove filter cake at temperatures above 165°F (preferably, up to 250°F or greater). Through filter cake removal resulting in improved permeability, the method provides for increased flow, production, and/or recovery of oil and gas hydrocarbons from a subterranean formation.

    摘要： Compositions and methods for triggering an exothermic reaction of an exothermic reaction component are provided. A method includes the steps of mixing the exothermic reaction component in an aqueous solution to achieve a pre-selected solution pH, where the aqueous solution operably delays triggering of the exothermic reaction upon reaching a pre-determined temperature of a hydrocarbon-bearing formation; disposing the exothermic reaction component within the hydrocarbon-bearing formation; applying microwaves to the exothermic reaction component, where the microwaves are operable to trigger the exothermic reaction of the exothermic reaction component; and generating heat and gas in situ by the exothermic reaction to increase pressure and temperature of the hydrocarbon-bearing formation proximate the exothermic reaction component.

    摘要： Provided herein are novel proppants for use in hydraulic fracturing. The proppant has a core substrate and a light-weight substrate. The light weight substrate comprises a plurality of composite particles; a filler material; and an adhesive. The filler material has a particle- distribution-size of about 5 percent to about 20 percent of the particle-distribution-size of the plurality of composite particles. Additional additives can be optionally added to light-weight substrate. The adhesive binds the light-weight substrate to the core substrate to produce the proppant having a specific gravity of about 1 g/cc. Proppant can travel with the carrier fluid in a frac fluid rather than settling out quickly or floating away.
