Paper presented at the Canadian International Petroleum Conference, June 17–19, 2008
Paper Number: PETSOC-2008-024
..., nitrite and ammonia in injection and produced waters were determined, as well as the activities of nitrate-reducing bacteria (NRB). Field-wide nitrate injection gave a 70% drop of aqueous sulfide within the first 5 weeks, after which the concentration recovered somewhat for the next 20 weeks. The activity...

... Abstract The application of nitrate or nitrite to remediate souring during waterflooding is proven technology with the objective of (i) removing sulfide produced by sulfatereducing bacteria (SRB) and (ii) inhibiting further sulfide production by the SRB. Nitrate or nitrite injection stimulates...
