ABSTRACT:
Disclosed are nonionic dihydroxypropyl hydroxyalkylcelluloses having a dihydroxypropyl M.S. of from about 0.1 to 1.2 and a hydroxyalkyl M.S. of from about 1.5 to about 3.0. The dihydroxypropyl hydroxyalkylcelluloses are capable of reacting with polyvalent metal cations, such as, titanium and zirconium, in an aqueous medium, such as a salt brine medium, to form viscoelastic gels useful in oil recovery operations.
