Experimental Studies on Corrosion Behaviors of Casing Steel N80 in High Salinity of Brine

Abstract:

Brine corrosion can remain a large obstacle to the rehabilitation project of Missan Oilfields in Iraq. To minimizecorrosion risks, the 13-3/8′′ casing steel, N80,has been employed to examine corrosion behaviors in simulated formation water (i.e., brine). The impact factors of corrosion such as temperature, ion contents, exposure time, and pH have been studied. Also, corrosion inhibitors available in brine have been screened by a static weight loss method. The results showed that effects of environmental and operational variables on N80 corrosion are fairly complicated; the corrosion inhibitor, HN-amph, exhibits excellent corrosion inhibition in brine. This work will provide important information for on-site application.
