Time-Resolved Pore-Scale Imaging of Multiphase Dissolution during CO2-Saturated Brine Injection into a Carbonate: Competition between Hydrocarbon Mobilisation and Swelling

Branko Bijeljic, Martin J. Blunt, Qianqian Ma, Rukuan Chai, Yanghua Wang, Zhuangzhuang Ma

Effective dissolution rates in residual-oil carbonate rock are controlled by the competition between hydrocarbon swelling and ganglion mobilisation.

Claims

C1strongest claim

These results show that the effective dissolution rate in residual-hydrocarbon-bearing carbonate depends dynamically on the competition between hydrocarbon swelling and ganglion mobilisation, governing advective access to surfaces.

C2weakest assumption

The interpretation that the rate suppression is primarily due to path-dependent loss of advective access (with subordinate contributions from H+ depletion and mass transfer), and that the three regimes observed in this Ketton limestone sample under the stated conditions generalize to other carbonates and field settings.

C3one line summary

Pore-scale 4D imaging demonstrates that hydrocarbon swelling and mobilisation compete to control the non-monotonic dissolution rate of carbonate by CO2-saturated brine via changes in advective access.
