Biocide testing for the application in the oil and gas industry

The paper discusses tests for effectiveness of three antibacterial substances for application in the national oil and gas industry. The substances were tested with reference to active cultures of microorganisms. These cultures were isolated, inter alia, from drilling fluids, produced waters and extraction sludge, and then multiplied and used in tests discussed in this publication. The tests demonstrated differences in particular tested substances in respect of effectiveness of their impact on aerobic and anaerobic bacteria and fungi. The results of the work will be used in industrial treatments in order to eliminate biogenic contamination, counteract biodegradation of drilling muds, and also for disinfection of reservoirs designed for storing water and other technological fluids.
