We present a novel stochastic time series model that integrates damping effects, fractional Brownian motion, and wavelet transforms to simulate CO 2 migration and diffusion behavior in complex porous media. Compared to traditional approaches, our model captures multi-scale heterogeneity and dynamic fluctuations more effectively, offering improved predictive accuracy at microscopic spatial and temporal scales. This approach provides a refined understanding of CO 2 transport mechanisms in tight reservoirs and supports the design of more efficient CO 2 -EOR and CCUS operations. carbon dioxide fractal Brownian motion wavelet transform damping porous media Full Text Additional Declarations The authors declare no competing interests.
