Several issues associated with microorganisms found throughout the petroleum industry include microbial influenced corrosion (MIC), biotic souring, and biofouling. Traditional methods for evaluating biocide efficacy within the petroleum industry have been focused specifically toward the planktonic, or free-floating, microorganisms. The sessile population, or the community of microorganisms contained within the biofilms that adhere to each other on a surface are not adequately assessed. Since microorganisms contained within biofilms can contribute to all three major microbial issues in the oilfield and the complexity of the microbial community effects the chemical treatment strategy, there is an increased importance associated with the ability to develop a representative, mature biofilm in a lab setting in order to evaluate the efficacy of the chemical treatments prior to implementation in the field. Currently, there are a variety of laboratory methods designed to grow biofilms. However, these methods suffer from many drawbacks. This includes large quantity of fluid required to achieve a once-through system, the number of samples available to test, and the reproducibility of the biofilm growth itself. The purpose of this paper will be to introduce a novel method that will allow for an increased scalability, reproducibility, and utility in laboratory biofilm studies. This knowledge will help in a better understanding of biofilms and facilitate the development of treatment strategies targeting biofilms.
