titleOfInvention | Viscous heavy brines and method for their manufacture |
abstract | Abstract Disclosed is a method of increasing the viscosity of heavy brines containing calcium chloride, calcium bromide, zinc bromide, or mixtures thereof, comprising adding to the brine certain homogeneously substituted cellulose sulfate esters. Such cellulose sulfate esters are effective viscosifiers for certain heavy brines depending on the degree of substitution of sulfate groups in the polymer. |
