    摘要： A method of servicing a well is disclosed. The method comprises mixing ingredients to form a well servicing fluid. The ingredients comprise (i) at least one surfactant chosen from alcohol ethoxylates, C4 to C12 primary alcohols and ethoxylated propoxylated alcohols, (ii) a zwitterionic polymer prepared by inverse emulsion polymerization of at least one monomer Ab comprising a betaine group and optionally one or more nonionic monomers Ba, and (iii) a saline based aqueous solution. The well servicing fluid is introduced into a hydrocarbon well.

    摘要： Hydraulic fracturing is conducted by use of a well treatment fluid which contains a guar gum derivative as viscosifying or gelling polymer, an organic zirconate complex of a zirconium metal and an alkanol amine as crosslinking agent and a hydroxylated glycine as crosslinking delaying agent. The fluid is characterized by a low pH, generally greater than or equal to 3.0 and less than or equal to 5.0.

    摘要： A non-aqueous well treatment fluid is provided containing a glycol-soluble polymer such as highly substituted hydroxypropyl guar in an alkylene glycol or alkylene glycol ether solvent. A non-aqueous slurry composition for use in preparing water-based well treatment fluids is also provided, having a glycol-soluble polymer such as highly substituted hydroxypropyl guar in an alkylene glycol or alkylene glycol ether solvent. A method is provided for utilizing such a slurry to prepare a water-based well treatment fluid, the method including loading a water-soluble polymer into the slurry, then metering the loaded slurry into water.
