Abstract:

A method of using a suppression factor fluid during a well activity is provided. The method comprising the steps of introducing a suppression factor fluid into a wellbore, the suppression factor fluid comprising an untreated divalent brine, and a suppression sugar alcohol, the suppression sugar alcohol in an amount operable to achieve a suppression factor of at least 0.1, wherein a density upper limitation of the suppression factor fluid is greater than the density upper limitation of the divalent brine; wherein the suppression factor fluid is in the absence of zinc; and completing the well activity in the wellbore, such that the suppression sugar alcohol inhibits crystallization during the well activity.
