Assessing geochemical reactions during CO2 injection into an oil-bearing reef in the Northern Michigan basin

Acid Water–Rock–Cement Interaction and Multicomponent Reactive Transport Modeling

“…Since carbonate rocks are common in reservoir and seal formations of potential CO 2 -storage sites worldwide (e.g. Midale carbonate unit in Weyburn, Emberley et al, 2004; sedimentary basins, Benson and Cole, 2008; Dover 33 reef in the Michigan Basin, Welch et al, 2019), research can help us to better understand the basic reaction mechanisms. Portland cement is placed between the borehole steel casing and the surrounding rock at CO 2 injection sites to prevent gas or fluid leakage.…”

Long‐term CO2 sequestration mechanisms and influence of injection mode in Zhujiang Formation of Pearl River Mouth Basin

“…The above sequestration mechanisms correspond to hydrodynamic trapping, dissolution trapping and mineral trapping, respectively 18,19 . The action time and contribution of these three sequestration mechanisms would be affected by the storage site condition 20–22 . Field‐scale numerical simulation is an effective and credible means to study the long‐term evolution of these three sequestration mechanisms under different conditions 23,24 .…”

“…18,19 The action time and contribution of these three sequestration mechanisms would be affected by the storage site condition. [20][21][22] Field-scale numerical simulation is an effective and credible means to study the long-term evolution of these three sequestration mechanisms under different conditions. 23,24 Yang et al 25 investigated the long-term CO 2 sequestration mechanisms in Liujiagou Formation sandstone using TOUGHREACT.…”
