Biocorrosion of Oil and Gas Field Equipment and Chemical Methods for Its Suppression. I

Abstract

Main groups of corrosive microorganisms are considered. The parameters of the medium that intensify biocorrosion and the conditions for the formation of biofilms are described. The mechanisms of biocorrosion induced by the main groups of unicellular microorganisms are proposed, and the characteristic types of biodamage, specified.

Colloid chemistry and experimental techniques for understanding fundamental behaviour of produced water in oil and gas production

“…The most abundant type of organics of the dissolved organic components, the short acids (or volatile fatty acids -VFA), are usually relatively harmless as they are readily biodegradable by the microorganisms in the seawater [29]. They can, however, contribute to the corrosion of the process equipment [30] and lead to increased biofilm formation in the process equipment [31]. The naphthenic acids in the water phase, which are of more environmental concern, are characteristic for process waters from the production of bitumen from oil sands [32,33],…”

Corrosion Behavior of Steel in Acidic Medium for Petroleum Systems

“…Corrosion affects every part of the steel structures of the petrochemical industries, some occur at faster rate while others at slow corrosion rate. Huge losses of revenue have been recorded in petrochemical industry as a result of corrosion maintenance, which ranges from million dollars to billions of dollars spent yearly (Ramraj and Anandaraj, 2014;Moiseeva and Kondrova, 2005;Koch et al, 2005;El-Yazgi and Hardie, 1998). Research showed that stainless-steel and carbon steel are generally used for petrochemical's structural equipment (Cui et al, 2006;Smith et al, 2000;Gutzeit, 2000;Breen, 1974;Chambers et al, 2011;Haruna et al, 2018).…”

Influences of Thermophilic Sulfate-Reducing Bacteria on the Corrosion of Carbon Steel at Different Temperature

“…Advances in Chemical Engineering: ICCMME 2011 generated by SRB was thiosulfate before the H 2 S was generated [9][10][11][12][13]. With the increase of temperature, the bisulphate was re-reduced by SRB.…”
