Abstract
Corrosion has been one of the primary mechanisms causing failures of infrastructure in the oil and gas industry. As fluid mechanics plays an essential role in internal corrosion of tubulars and pipelines, it is expected that a complete understanding and modeling of tubular/pipeline corrosion depends on integration of the fluid flow with the electrochemical corrosion reactions occurring on the steel. In this work, the fluid flow in downhole steam-assisted gravity drainage (SAGD)/CO2 co-injection tubulars and upstream gathering pipelines in oil production is modeled by computational fluid dynamics (CFD) simulations, and the potential locations where corrosion occurs are identified. Models are developed for prediction of corrosion rate of steel tubulars and pipelines under the operating conditions. The mechanism and parametric effects of pipeline corrosion in CO2-containing oil-water emulsions is investigate experimentally using flow loop system.
