A strain of sulfate reducing bacteria (SRB) was isolated from the inner deposits of a pipeline that transports sour gas in the Marine Region of Mexico. The sample was collected from the 36” Atasta - NohochA pipeline. The strain was identified by 16S rRNA sequential analysis as Desulfovibrio sp. The physiological kinetics in Posgate Cmedia showed sulfate consumption and 30 mM sulfide production up to 250 h. The corrosion rate was evaluated with API XL 52 probes by weight loss and three electrochemical techniques: Rp, EIS and electrochemical noise. When Desulfovibrio sp. was inoculated in the Posgate C media, a reduction in the corrosion rate vs. time was measured by Rp and EIS. This behavior was attributed to the formation of a FeS film and biofilm, which form an effective diffusion barrier. On the other hand, the electrochemical noise measurements indicated that a localized corrosion process took place on the surface sample, which was confirmed by SEM analysis.

An analytical approach that can discriminate between various forms of microscopic corrosion initiation has been employed in natural gas gathering and storage facilities.  Information provided by the analysis of electron microscope coupons has led toward the better understanding and diagnosis of the initial stages of internal corrosion in natural gas gathering and storage facilities.
