    Abstract: Viscous polybutenes of number average molecular weight (Mn) in the range of about 300 to about 3,000 have improved reactivity with intramolecular anhydrides of unsaturated aliphatic dicarboxylic acids when such polybutenes contain rather small amounts, i.e., 5 to 200 ppm, of brominated dialkylhydantoin. Preference is given to such bromine containing compounds having a sufficient vapor pressure at a temperature in the range of 100* to 300*C. to be substantially completely removed at absolute pressures in the range of 5 to 760 mm Hg. Use of such polybutenes containing such brominated compounds in the addition reaction with said unsaturated anhydrides can reduce formation of undesired tarry product resulting from polymerization and/or thermal decomposition of the unsaturated anhydrides and enhance yield of desired alkenyl-substituted anhydride.

    Abstract: Improved sweep efficiency in oil-bearing reservoirs having high permeability streaks therein can be effected by first injecting a gel-forming solution consisting essentially of a dichromate activator in a lignosulfonate solution, modified by the presence of an alkali metal halide or an alkaline earth metal halide, such as, for example, sodium chloride or calcium chloride. This system has the advantage of high temperature tolerance and the gelforming characteristics thereof are not appreciably affected either by formation brine or CO2. Gel-forming solutions can be designed requiring from 10 to 2,000 hours to form a gel.
