    摘要: Gel compositions are disclosed including a high molecular weight water-soluble acrylamide polymer, a chromium III/carboxylate complex capable of crosslinking the polymer and a buffered aqueous solvent. The gel compositions are prepared at the surface and injected into a zone of a formation assessable by a wellbore to form a continuous single-phase gel. The gel compositions may be tailored to a specific formation by predetermining gelation rate, gel strength and/or gel stability to form gels having predetermined properties suitable for the zone.

    摘要: Coacervate gels having excellent shear viscosities and other properties are made with anionic or cationic polymers, a smaller amount of a surfactant having a charge opposite that of the polymer, and a hydrophobic alcohol and an effective amount of a phosphorus-containing compound sufficient to increase the viscosity of coacervate gels up to 3 times as compared to the gels in the absence of the phosphorus-containing compound. The Zeta Potential of the gel is maintained at an absolute value of at least 20. Optional gel promoting additives include betaines and amine oxides. A preferred gel comprises poly diallyl dimethyl ammonium chloride, a lesser amount of sodium lauryl sulfonate, and lauryl alcohol. The gels are particularly useful in well drilling fluids and well fracturing fluids.
