It has been shown that anthraquinone inhibits the ability for sulfate-reducing bacteria (SRB) to respire using sulfate as an electron acceptor. This property has been used to develop specific treatments for oilfield water systems to reduce the generation of H2S and the formation of iron sulfides. In this paper, results from laboratory and field studies showing the synergistic effect of treating oilfield produced waters with both anthraquinone and acrolein are discussed. Results from these studies indicate that the use of anthraquinone can extend the duration of effectiveness of this biocide and improve the quality of the water for injection.
