    摘要： Methods comprising: providing a consolidating agent emulsion composition that comprises an aqueous fluid, a surfactant, and a consolidating agent; and coating at least a plurality of particulates with the consolidating agent emulsion to produce a plurality of consolidating agent emulsion coated particulates. Methods comprising: providing a treatment fluid comprising a consolidating agent emulsion comprising an aqueous fluid, an amine surfactant, and a consolidating agent; and introducing the treatment fluid into a subterranean formation. Methods comprising the steps of: coating a plurality of particulates with a consolidating agent emulsion to produce consolidating agent emulsion coated particulates; providing a treatment fluid comprising an aqueous fluid, a surfactant, and a consolidating agent; introducing the treatment fluid into a subterranean formation. Consolidating agent emulsion compositions comprising: an aqueous fluid; a surfactant; and a consolidating agent comprising a non-aqueous tackifying agent or resin.

    摘要： Clean-up additive compositions may be used to enhance the clean-up of VES-gelled aqueous fluids in a wide range .of .applications and VES fluid compositions, including use of an internal, breaker system. The compositions are microemulsions that may include, but npt necessarily be limited to, at least , one viscosity reducing agent, at least one solubiliidng agent, at least one desorptiÌn agent and at least one water wetting agent. One non-limiting embodiment of a specific microemulsion includes an unsaturated fatty acid oil, a glycol, a sorbitan ester/ethoxylated sorbitan ester mixture, and an alkyl sulfonate. Microemulsions may perform one or more of the following functions: keeping the reservoir water wet; keeping surface tension reduction low; demulsifying reservoir crude oils and aqueous VES fluids; dispersing and solubilizing the by-products generated when breaking the VES gel; and/or limiting the amount of VES residue on reservoir minerals.

    摘要： A method of producing subterranean fractures in geologic formations for the extraction of hydrocarbons includes flowing an air and fuel mixture into a well hole. The well hole may then be sealed with a packer plug creating a compression chamber with the air and fuel mixture. A liquid, such as water, may be pumped into the well hole to create pressure in the compression chamber. The build-up of pressure eventually causes autoignition of the air and fuel mixture which fractures the formation. The water may then rush into the compression chamber which thermally shocks the area causing additional fractures. The water may vaporize to steam and thoroughly disinfect the well hole eliminating the need for added biocides.
