    摘要: A system includes a hydraulic fracturing fluid including a polymeric constituent and an additive having particles including poly-vinyl acetate in an amount sufficient to control fluid loss. The system includes a formation of interest having a downhole temperature, and the particles including poly-vinyl acetate have a size and/or shape such that the poly-vinyl acetate hydrolyses at the downhole temperature. The particles may have a size and/or shape such that the particles are deformable at the downhole temperature. The poly-vinyl acetate in the particles may be a part of the particle substrate, a coating on the particles, and/or the entire particle may be poly-vinyl acetate. The poly-vinyl acetate may be included in any portion of the hydraulic fracturing fluid, or only the portion of the hydraulic fracturing fluid that is not proppant laden.

    摘要: A treatment fluid for treating a subterranean formation penetrated by a wellbore is formed from water, a polyacrylamide in an amount of less than about 0.5% by weight of the fluid for reducing friction of the fluid and a stabilized peroxide breaker. A method of treating a subterranean formation penetrated by a wellbore is carried out by forming treatment fluid comprising water, a polyacrylamide in an amount of less than about 0.5% by weight of the fluid for reducing friction of the fluid and a stabilized peroxide breaker. The treatment fluid is introduced into the formation through the wellbore at a pressure above the fracture pressure of the formation.

    摘要: A well treatment microemulsion for use in a subterranean formation is disclosed, the microemulsion comprises a solvent blend comprising a solvent and a co-solvent; a surfactant blend comprising a surfactant, wherein the surfactant blend is able to give formation intermediate wettability properties; an alcohol; and a carrier fluid; wherein the alcohol, the solvent and surfactant blends are combined with the carrier fluid to produce the well treatment microemulsion. By intermediate wettability it is meant that the water has an advancing contact angle on the surface between 62 and 133 degrees. The associate method of treating a subterranean formation of a well with the microemulsion and the associate method of modifying the wettability of the formation with the microemulsion are also disclosed.
