Control of oilfield biofouling

摘要

The invention describes a process for controlling contamination of oil production system waters by sessile bacteria, comprising a) addition of a slug dose of a biologically effective amount of a quick-kill biocide, simultaneously with or followed by b) intermittent addition of a biologically effective amount of a control biocide. This dosing regime is found to be surprisingly effective when compared with known dosing regimes.
