Abstract

Produced (oilfield) brines are rich in dissolved salts and thus have high ionic strength as well as conductivity. Further, they are in contact with ferrous metals used for oil- and gasfield installations. Thus, the potential for electro-chemical corrosion reactions in these environments is high. The latent consequences are e.g. general metal wastage, pitting, embrittlement and cracking which all can lead to equipment failure, or even catastrophic results like major oil spills. One of the most abundant methods to mitigate such events is the use of organic corrosion inhibitors (CIs). No doubt, film-forming organic CIs are one of the most important oilfield production chemicals as ranked by volumes used globally. There is a constant need to develop new chemistry in this field, driven by requirements for more environmentally adapted products, lower dosages, higher performance and meeting new compatibility and high temperature/high pressure (HTHP) challenges. The development and testing of of corrosion inhibitors for oil- and gasfield (offshore) use has been thoroughly reviewed (1).
