1. Pore-scale fluid dynamics resolved in pressure fluctuations at the Darcy scale. Geophysical Research Letters.
   Spurin, C., Roberts, G. G., O'Malley, C. P. B., Kurotori, T., Krevor, S., Blunt, M. J., and Tchelepi, H. A. [Paper] [Arxiv]
   

   This work shows that the underlying pore scale dynamics manifest in the fluctuations in the pressure signal. The power spectra provide useful information into the dynamics without imaging.
   
2. Dynamic Mode Decomposition for Analyzing Dynamics in Multi-phase Flow in Porous Media. AWR.
   Spurin, C., Berg, S., Armstrong, R. and McClure, J., [Paper] [Arxiv]
   

   DMD is a dimensionality reduction algorithm. In this paper we show that it can be used to highlight dynamics that are difficult to capture with the naked eye.
3. Mechanisms controlling fluid breakup and reconnection during two-phase flow in porous media. Physical Review E.
   Spurin, C., Bultreys, T., Bijeljic, B., Blunt, M.J. and Krevor, S., [Paper] [Arxiv]
   

   This work explores the controlling mechanisms for fluid breakup and reconnection. We show that the Capillary number (Ca) and viscosity ratio (M) can be used to characterize the flow regime expected. We show that, for CO₂ storage, intermittent flow pathways will be present. These pore-scale dynamics must be incorporated into large-scale reservoir models to accurately capture the movement and trapping of CO₂ in the subsurface.
4. Intermittent fluid connectivity during two-phase flow in a heterogeneous carbonate rock. Physical Review E.
   Spurin, C., Bultreys, T., Bijeljic, B., Blunt, M.J. and Krevor, S., [Paper] [Arxiv]
   We observe that intermittent pathways heavily influence the connectivity of the gas. This is because intermittent flow connections are more likely in regions in the pore space where the gas phase is poorly connected, or the pore space itself is poorly connected. Intermittent pathways connect regions of gas that are otherwise disconnected from the main flow pathway across the core.
5. Real-time imaging reveals distinct pore scale dynamics during transient and equilibrium subsurface multiphase flow. WRR.
   Spurin, C., Bultreys, T., Rücker, M., Garfi, G., Schlepütz, C.M., Novak, V., Berg, S., Blunt, M.J. and Krevor, S., [Paper] [Arxiv]
   
   In this paper we show how transient dynamics are distinct to steady-state dynamics. To accurately capture the movement of CO₂ in the subsurface we must include transient dynamics in our large scale models.
6. The development of intermittent multiphase fluid flow pathways through a porous rock. AWR.
   Spurin, C., Bultreys, T., Rücker, M., Garfi, G., Schlepütz, C.M., Novak, V., Berg, S., Blunt, M.J. and Krevor, S., [Paper] [Arxiv]
   
   Intermittent pathways allow for more efficient propagation of fluids.
7. Red Noise in Steady-State Multiphase Flow in Porous Media. WRR.
   Spurin, C., Rücker, M., Moura, M., Bultreys, T., Garfi, G., Berg, S., Blunt, M.J. and Krevor, S., [Paper] [Arxiv]
   

   We transform the pressure data into the frequency domain using Fourier transformation. We observe that red noise (black dashed line in figure) is present for intermittent pathway flow during multiphase flow.

Miscellaneous

I am on the committee for the Porous Media Tea Time Talks. These are a series of YouTube webinars that give Early Career Researchers the chance to showcase their work. Subsrcibe to our channel and check out the talks!

I developed a workflow to segment multiphase images. The workflow for this is available here:
