Recently we were asked by a CT Client “Why do I need to treat the water during mill-outs, if it was treated during the frac? To avoid pre-mature string failures and corrosion of down-hole tools, take the time to test the circulated fluids to understand the overall microbial level and threat present. Use the data to drive decisions that control the risk otherwise you are placing your trust in the Frac Company choosing a biocide package that was appropriate, effective and geared to managing microbes well into mill-out operations. It takes the guessing out of the equation and ensures that water in contact with your strings and tools does not compromise the integrity of your equipment for future jobs.
