Abstract
Analysis of microbial community structure of a low sulfate oil producing
facility in Nigeria using 16S rRNA gene sequencing technique revealed
dominance of oil degrading and nitrate reducing bacteria and methanogenic
archaea in produced waters and oil samples namely, Marinobacter (37%),
Azovibrio (21%), Thauera (10–28%), and Methanolobus (22%). On the contrary,
the associated oil pipeline samples revealed massive dominance of potentially
corrosive Methanolobus (60%) and Methanobacterium (25-27%). Further
experimentation shows that the methanogens implicated in oil pipelines are
corrosive moderate halophile that utilizes H2/CO2 and methanol as substrates.
More emphasis should therefore be on methanogenic archaea as opposed
to sulfate reducing bacteria (SRBs) during mitigation plans for microbially
induced corrosion (MIC) in a low sulfate oil producing facility
