Paper presented at the CORROSION 2021, April 19–30, 2021
Paper Number: NACE-2021-16868
... Abstract The high productivity of pre-salt exploratory wells led to a re-evaluation of Petrobras' model of offshore oil production and exploration. We present here the study that allowed the conversion of exploratory wells into producers, based on the corrosion resistance of carbon steel...

... in the conferences of CORROSION 2018 and 2019. In this paper, results of corrosion rates of carbon steel in sand containing sea water, which were measured by the CIPE method were discussed. As a result, it was confirmed that the CIPE method was also useful to monitor corrosion rates of carbon steel in soil...
