  • Patent number: 8517100
    Abstract: Single-phase microemulsions, comprising a solvent, a surfactant blend and a carrier fluid, are effective spacer fluids for use during cementing operations. The solvent may be selected from the group consisting of monoterpenes, diterpenes, and alkyl or aryl esters of short-chain alcohols. The surfactant blend comprises a water-wetting surfactant or nonionic surfactant, a co-surfactant and an oil-solubilizing surfactant. The carrier fluid is aqueous. The solvent and surfactant blend are combined with the carrier fluid to produce the well-treatment microemulsion.

  • Publication number: 20120227967
    Abstract: Particles are provided in which proppant and gravel used in treating subterranean wellbores are coated with most or all of the chemical components needed to make the carrier fluids used to deliver them. The components come off the proppant or gravel during injection and viscosify the fluid. Components may be applied in layers, as uniform or non-uniform mixtures, or both. Particle coatings may include gas pockets that reduce the particle density.

  • Publication number: 20110315382
    Abstract: A composition for treating a subterranean formation is formed from water, a water-soluble polymer and a crosslinking system. The crosslinking system utilizes 1) primary crosslinking agent of at least one of a dialdehyde benzene source, a dioxane, and a trioxane, 2) a secondary low temperature organic crosslinking agent that generates aldehyde, and 3) a phenol source. The crosslinking system provides the composition a delayed gel time of about 2 to about 20 hours at temperatures of about 250° F. (121° C.) or higher. A method of treating a subterranean formation penetrated by a wellbore is also accomplished by forming a treatment fluid from the composition and introducing the treatment fluid into the formation through the wellbore.
