Top of the Line Corrosion (TLC) has been a serious issue for the Oil & Gas industry. Conventional inhibition techniques are either too expensive or do not seem to provide enough protection to the steel surface at the top of the pipe. A novel idea is to inject the corrosion inhibitor within a foam matrix. The foam slug is first formed at an injection port and carried along the pipe by the gas phase. This process ensures homogeneous delivery of the inhibitor to the pipe wall along pipe sections suffering from TLC. A NACE 2011 publication (Part I) addressed the chemistry work relating to screening various foaming agents and corrosion inhibitors for compatibility issues and foam stability criteria. This paper presents a more comprehensive study performed in an innovative glass cell setup which consisted of a foaming cell and a corrosion cell in order to simulate intermittent contact between the foam and the steel surface. Large scale flow dynamics tests were also performed in flow loop to investigate foam stability as a function of gas velocity. Corrosion measurements were performed using electrochemical techniques (EIS LPR potentiodynamic sweep) and electrical resistance measurements. SEM/EDS and AFM were also used in order to define the properties of the corrosion product film.
