... occurs, identifying potential internal corrosion locations is crucial for mitigation and repair. Two main methods are utilized for identifying potential locations of internal corrosion: ILI and ICDA. In-Line Inspection ICDA methodology for pipelines carrying normally dry natural gas can be found...

... for AC mitigation design. A major technical challenge during modeling often results from unavailable current loads of collocated powerlines. This report introduces our experience regarding this situation and provides a solution option. It is demonstrated that current loads can be estimated via simulating...

... problems with zonal control of the squeeze treatments and limited ion data was available. The production history for well A-01 is shown in Figure 2 . It shows the production of formation water (FW) and SW, as well as the timing of squeeze treatments to try and mitigate scaling. Abstract The impact...

... Offshore oil production is susceptible to internal corrosion, which can occur through microbiologically influenced corrosion (MIC) caused by biofilm-forming sulfate-reducing prokaryotes (SRP). The oil and gas industry relies primarily on biocides and mechanical cleaning to mitigate MIC. Halophytes (salt...

... in an effort to draw some parallels, but again, that method is not totally definitive. One way to definitively prove whether capacitive effects will exist for an AC mitigation system is to install the system and conduct direct testing. A test device is currently available that has a capacitor to simulate...
