Abstract:
At least one nucleic acid from a sulfate-reducing bacteria (SRB) may be extracted from an oilfield fluid and may be amplified by a PCR amplification method in the presence of at least one primer to form an amplification product. The primer(s) may be or include a sequence including, but not necessarily limited to, SEQ ID NO:1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, and mixtures thereof. The amplification product may be hybridized with a probe specific for a fragment of an alpha subunit of an APS gene, and a presence of hybridization and a degree of hybridization may be detected.

Claim (Index 7):
A method of decreasing sulfate-reducing bacteria (SRB) in oilfield fluids comprising:\n altering an amount of a microbial agent within an oilfield fluid based on an amount of at least one SRB within the oilfield fluid to form an altered oilfield fluid; wherein the oilfield fluid is selected from the group consisting of oilfield water, a production fluid, a fracturing fluid, a drilling fluid, a completion fluid, a workover fluid, a packer fluid, a gas fluid, a crude oil, and mixtures thereof; wherein the amount of the at least one SRB is determined by:\n amplifying at least one nucleic acid of the at least one SRB in the presence of at least one primer to form an amplification product; wherein the at least one nucleic acid is extracted from the oilfield fluid prior to amplifying the at least one nucleic acid; wherein the at least one primer comprises a sequence selected from the group consisting of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, and mixtures thereof; \n hybridizing the amplification product with a probe having a nucleotide sequence selected from the group consisting of SEQ ID NO: 16, SEQ ID NO: 17, SEQ ID NO: 18, SEQ ID NO: 19, and mixtures thereof; and \n detecting a presence of hybridization and a degree of hybridization; wherein the presence of hybridization indicates the presence of the at least one SRB; and wherein the degree of hybridization enumerates the at least one SRB; and \n decreasing the amount of SRB by killing and/or deactivating the SRB.
