Impact of Velocity-Dependent Relative Permeability and Fines Migration on CO2 Storage in Aquifers: A Hybrid Analytical-Numerical Upscaling Framework
The aim of this study is to develop an analytical model for axisymmetric gas-water flows in heterogeneous geological formations applicable to carbon dioxide (CO2) storage in deep saline aquifers. The novel method integrates numerical upscaling with an analytical reservoir model for predicting sweep and injectivity du...
