A study on the corrosivity of field produced water obtained from in-situ oil sands operators to UNS G10180 carbon steel. Rotating cylinder electrode (RCE) and rotating cage autoclave (RCA) systems were used as test methods. The susceptibility of the carbon steel to pitting was also evaluated.
In-situ oil sands water treatment systems (WTS) used to treat and recycle produced water to ultimately supply steam to the steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) processes have noted failures associated with corrosion including erosion-corrosion under deposit corrosion (UDC) fouling scaling and localized corrosion among others. Oil sands operators employ corrosion monitoring tools chemical treatment and/or material selections to resolve integrity related issues. However the unpredictable occurrences of serious corrosion issues related to the complex and constantly changing water chemistries make it difficult to choose the appropriate preventative and mitigation strategies. This is further complicated by the effects of operating conditions; such as temperature pressure and flow geometry.This paper presents the corrosivity of field produced water obtained from in-situ oil sands operators to UNS G10180 carbon steel. Rotating cylinder electrode (RCE) and rotating cage autoclave (RCA) were used as test methods. The susceptibility of the carbon steel to pitting was also evaluated using cyclic potentiodynamic polarization method. The findings indicated that corrosion rates were highly influenced by water chemistries and operating conditions.Key words: Produced water Oil sands Corrosion RCE RCA SAGD CSS In-situ WTS.
