摘要

A problem of uncontrolled internal corrosion of over 20 mpy was root cause analyzed within a systemof pipelines connecting a set of oil wells onshore central Gulf of Mexico coastline. The root causeanalysis was focused on a detailed characterization of the gas, mostly methane, and liquid phases,mostly genic waters as well as CO2, H2S, chlorides and MIC bacteria. The metallurgy of the corrosiondamage over the steel pipeline involving both zone of uniform corrosion as well as special points oflocalized corrosion. In the past these pipelines received unsuccessful chemical treatments. Both theinhibitor and the dosage were not available. A trial of a new palm oil based corrosion inhibitor wasperformed. The corrosion inhibitor passed successful testing in the laboratory employingelectrochemical testing by linear polarization resistance as well as harmonic analysis. The corrosioninhibitor formulation was furthermore adapted for massive fabrication involving a set of parallelvariables from pipeline engineering such as foam formation elimination, not gel formation and other.The program was conducted producing improvements from the onset. Corrosion inhibitor injectionwas immediately and a program of pipeline cleaning was launched. In the first four months of the newcorrosion inhibitor solution the results produced the desired target of overall compliance to the internalpipeline corrosion control specification below 2 mpy.
