Uncontrolled biological growth downhole typically results in the proliferation of Sulfate Reducing Bacteria (SRB) this produce poisonous and corrosive H2S. This can also result in soured product within the formation and can even seal off the gas formation. The cost implications of this can be catastrophic, so a holistic monitoring program including ATP monitoring can serve as the ideal first line of defense for biological control.
The mechanisms of corrosion are not always well understood, but microbially influenced corrosion (MIC) is undeniably a significant contributor. Once a biofilm community has become established, microorganisms within the community degrade process equipment and compromise their integrity. A rigorous control program supported by effective monitoring tools such as ATP monitoring. ATP testing will enable on-the-spot control to prevent biofilm formation and reduce the risk of MIC.
Microbiological methods for oilfield samples tend to be time-consuming to acquire results. Rather than spending several days to acquire critical data, ATP testing can serve as the ideal tool to provide rapid feedback and guide mitigation activities on-site and on-the-spot.
