“…However, in practice, the use of water is inevitable in CO 2 injection. With increasing demands on carbon reduction, a huge amount of CO 2 was captured from industrial plants and injected into deep reservoirs for the enhancement of oil/gas recovery and for the permanent storage of carbon . For example, in Shengli oilfield, it can improve the recovery of crude oil by 6.7% compared with the conventional water injection process, and simultaneously, the sequestration rate of CO 2 can reach 60.5% .…”

An analytical model is proposed to describe the corrosion risk profile of a well tube in water alternating gas (WAG) CO 2 injection conditions based on the assumption that the drying process of the water layer on the inner wall of the well tube plays a crucial role in controlling corrosion. In this model, the fluid properties, the thermodynamic equilibrium of CO 2 and water steam, and an empirical CO 2 corrosion equation are systematically considered. The description by this model reasonably indicates that fast injection can decrease the corrosion risk and push the highest risk region to a deeper zone, while a longer drying time for a thicker water layer left on the well inner wall can lead to higher corrosion risk. It can also be deduced that the offshore WAG case is more aggressive than the onshore case and some mitigation strategies are suggested for reducing the corrosion risk. These should be helpful for corrosion management and leakage monitoring in the practical WAG CO 2 injection.

“…Combined with CCS techniques, CO 2 enhanced oil recovery (EOR) has proved to be currently applicable in China for reducing CO 2 emissions (Zhang et al, 2013;Lv et al, 2015). The CO 2 -EOR technique may produce a net zero emission of CO 2 , as it can store carbon underground during oil production.…”

Carbon capture and storage (CCS) combined with CO 2-enhanced oil recovery (EOR), has been recently viewed as an economical and effective method for the reduction of carbon emissions. However, corrosion is a challenging issue in the whole chain process of CO 2-EOR production if water presents and mild steel pipeline is used. In this paper, the corrosion risk of pipeline at different stages of CO 2-EOR production is systematically assessed based on a detailed analysis of the fluid characteristics. According to the fluid state of CO 2 , water and crude oil, current understandings on the corrosion behavior of steel materials in multiphase flow conditions are reviewed. Furthermore, the intermittent water wetting phenomena and the fluid behavior of water droplets or clusters in an electrolyte/non-electrolyte emulsion are correlated with the steel corrosion performance, providing new insights into the corrosion phenomena. Besides application of corrosion resistant materials and corrosion inhibitors, tailoring of processing parameters, such as enhancing the water entrainment, shortening the water contact time, and reducing the solution corrosivity, is highly recommended as an effective method for corrosion control in aggressive CO 2-EOR production conditions. Based on these, some important future research topics on the corrosion in multiphase fluids are suggested.
