Methods for evaluating the impact of chemical products on produced water

Abstract

The present invention refers to a method for evaluating the impact of chemical products on the OGC of produced water, comprising the steps of: (i) preparation of synthetic emulsions using oil mimicking produced water, produced water mimicked with the chemical product whose impact is to be evaluated, and saline water with said chemical product (without oil); (ii) measurement of the OGC of the samples; and (iii) evaluation of the obtained data. Further, the invention refers to a method for evaluating the impact of chemical products on the reinjection of produced water, comprising the steps of: (I) preparation of synthetic emulsions using oil mimicking produced water and produced water mimicked with the chemical product whose impact is to be evaluated; (II) measurement of the OGC of the samples; (III) measurement of the filtration time; and (IV) evaluation of the obtained data.
