Corrosion inhibitor studies on oil well tubular steels in hydrochloric acid

Abstract

The article describes some of the inhibitor formulations which were prepared from indigenous chemicals and their effectiveness in controlling corrosion of two oil well tubular steels, J-55 and N-80 steels, in hydorchloric environment. Preliminary experiments at 308K using electrochemical polarization technique indicated that the prepared additives were comparable in performance to 1-octyn-3-ol. Weight loss studies at a higher temperature of 383 plus/minus 2K in a specially designed glass cell showed that one of these additives was very effective although not matching with the performance of 1-octyn-3-ol.
