Pipelines play an extremely important role in the transportation of gases and liquids over long distance throughout the world. Internal corrosion due to microbiologically influenced corrosion (MIC) is one of the major integrity problems in oil and gas industry and is responsible for most of the internal corrosion in transportation pipelines. The presence of microorganisms such as sulfate reducing bacteria (SRB) in pipeline system has raised deep concern within the oil and gas industry. Biocide treatment and cathodic protection are commonly used to control MIC. However, the solution is too expensive and may create environmental problems by being too corrosive. Recently, Ultraviolet (UV) as one of the benign techniques to enhance mitigation of MIC risk in pipeline system has gained interest among researchers. An amount of 100 ml of modified Baar’s medium and 5 ml of Desulfovibrio vulgaris (strain 7577) seeds was grown in 125 ml anaerobic vials with carbon steel grade API 5L-X70 coupons at the optimum temperature of 37°C and pH 9.5 for fifteen days. This was then followed by exposing the medium to UV for one hour. Results from present study showed that UV radiation has the ability to disinfect bacteria, hence minimizing the risk of metal loss due to corrosion in steel pipeline.

AbstractMicrobiologically influenced corrosion (MIC) is recognized as a considerable threat to carbon steel asset integrity in the oil and gas industry. There is an immediate need for reliable and broadly applicable methods for detection and monitoring of MIC. Proteins associated with microbial metabolisms involved in MIC could serve as useful biomarkers for MIC diagnosis and monitoring. A proteomic study was conducted using a lithotrophically-grown bacterium Desulfovibrio ferrophilus strain IS5, which is known to cause severe MIC in seawater environments. Unique proteins, which are differentially and uniquely expressed during severe microbial corrosion by strain IS5, were identified. This includes the detection of a multi-heme cytochrome protein possibly involved in extracellular electron transfer in the presence of the carbon steel. Thus, we conclude that this newly identified protein associated closely with severe MIC could be used to generate easy-to-implement immunoassays for reliable detection of microbiological corrosion in the field.

Rapid development of an oil and gas industry in the north of Western Siberia in the middle of the 20th century has demanded a significant amount of the electric power. This strategic task was carried out step by step in the neighborhood of Surgut (the largest oil and gas industry center on the Middle Priobye). Two gas-fired power stations have been consistently constructed. The integrated reservoir cooler has been built on the river Chernaya for cooling of circulating water in the system of reverse water supply of power plants. The article presents the assessment of consequences of flooding at construction of the Surgut reservoir. The total area of the water area of a reservoir is 2211 hectares, including 50% of forest, 20% of meadow, 5% of peat bog communities were under flooding. The authors of the paper develop the basic ecological map of the reservoir and neighborhood with the indication of natural and technogenic objects. Moreover they give the results of two years' monitoring of microbial community structure in the coastal zone of the reservoir cooler. They find it is important to provide the assessment of intensity of self-cleaning processes of the water object and analyze the sources of anthropogenic load on the water object. The microbiological methods which important to use for bio indication of an ecological condition of the Surgut reservoir have allowed to estimate the trophic status, to reveal ecologically unsuccessful sites of the water area, and to define intensity of self-cleaning processes in the water body.
