The persistence of biocides formulated in glutaraldehyde and acrolein were tested in different produced water environments using a calorimetric general aldehyde detection method based on metaphenylenediamine. The objective of Phase 1 (laboratory study) was to characterize the persistence of acrolein and glutaraldehyde in water samples representative of the environments to which the biocides has been applied. To validate the test results, some duplicate samples were analyzed using gas chromatographic (GC) methods and repeat trials were done on certain tests. The objective of Phase 2 (field assessment) was to compare the Phase 1 results on formation waters to actual field data. At the study site, monitoring of biocide residuals had been done by the chemical vendor at all treated wells. The data provided information on glutaraldehyde and acrolein residuals for one gas withdrawal (winter) season. The data were compiled so that persistence/degradation graphs could be constructed for the biocides in each formation. These field data were then compared to the Phase 1 results. The persistence of the biocides in each environment tested was shown to be unique, but repeatable.
