| Abstract: | Virgin cores and production fluids were obtained from seven wells, ranging in depth from 805 ft to 14 492 ft, and examined for the presence of sulfate-reducing bacteria (SRB) using Rosenfeld's sulfate-reducing medium modified by using crude oil in place of lactate. Cores from an additional six wells, ranging in depth from 1160 ft to 13 337 ft were tested for SRB using the modified Rosenfeld medium and API-sulfate-reducing medium. Produced waters from five of the six wells were tested also. All of the eleven produced water samples were positive for SRB while H2S production was not detected from the core samples. |
