the results support the notion that the addition of nitrate, at this
particular oil reservoir, can benefit MEOR by stimulating the proliferation of fortuitous
biosurfactant-producing bacteria. Higher nitrate concentrations exceeding the stoichiometric
volatile fatty acid (VFA) biodegradation demands and/or the use of alternative biogenic
souring control strategies may be necessary to warrant effective SRB inhibition down gradient
from the injection wells.
