Close proximity of high voltage lines and metallic pipelines becomes more frequent. This paper presents a recently developed simulation software to facilitate prediction and mitigation. Flexible (no limitation on number of pipes, transmission lines, bonds, groundings, coating and soil resistivity), user-friendly and robust.
Underdeposit corrosion (UDC) has been recognized by the oil and gas industry as a major threat to the integrity matrix of the production and transportation of oil and gas and has frequently been blamed for high corrosion rates and loss of containment during operations.
The content of this NACE International CorrCompilation: Underdeposit Corrosion covers a wide range of topics that were assembled to help the reader better understand and assess UDC threat, determine the corrosion mechanism(s) responsible for the UDC, and adopt the appropriate mitigation strategies to target the active corrosion mechanism(s). The topics include proper identification and characterization of the deposits encountered in oil and gas production and transportation systems; laboratory UDC testing methods to determine responsible UDC corrosion mechanism(s) and evaluate inhibitor performance; UDC threat assessment through modeling and prediction of solids transport and settling; Internal Corrosion Direct Assessment (ICDA) methods as a means to assess UDC threat; identifying and applying appropriate UDC preventive and mitigative strategies; and finally, case studies to elucidate real examples of how UDC was identified and managed.
