In this paper the application of corrosion management principles is shown to identify a clear path for managing MIC in for example crude oil transport, multiphase gathering and water injection pipeline systems. The basic steps of corrosion threat assessment, mitigation selection...

...In order to understand the effect of crude oil on steel corrosion, an understanding of the basic nature of crude oil is needed. This includes both the physical and chemical properties of crude oils and the various characterizations used for crude oils. Crude oil is a chemically complex liquid phase...

Tests of corrosion under deposits indicated no significant differences between the three types of oil. Tests...

... filtered from water samples from sweet crude oil and sour crude oil pipelines was investigated with a 16S rRNA gene 454 pyrosequencing method. A total of ~5800 microbially identifying 16S rRNA gene sequences were obtained, of which ~3500 sequences were associated with the sweet crude sample and ~2300 were...

... and will be referred to as the “laboratory cell” throughout this report. Oil Flow Loop A pilot scale crude oil flow loop was constructed and utilized to evaluate MIC/UDC under flowing oil conditions using an MEA probe ( Figure 2 ). The flow loop had previously been developed for early stages of a related testing...
