Method of increasing the rate of hydration of activated hydroxyethyl cellulose compositions |
摘要 |
A method of producing a well servicing fluid containing zinc bromide in which an activated hydroxyethyl cellulose is either admixed with a zinc bromide solution containing above about 30% by weight zinc bromide, or, in the alternative, is admixed with a non-zinc bromide containing solution to produce a viscosified solution which is then admixed with a zinc bromide containing solution.
