Effects of Enzymatically Induced Carbonate Precipitation on Capillary Pressure–Saturation Relations

Leakage mitigation methods are an important part of reservoir engineering and subsurface fluid storage, in particular. In the context multi-phase systems e.g., CO2 a reduction intrinsic permeability is not only parameter to influence potential flow or leakage; parameters, such as relative capillary pressure, key parameters that likely be influenced by pore-space due leakage methods, induced precipitation. this study, we investigate effects enzymatically carbonate precipitation on pressure–saturation relations first step accounting for parameters. This is, our knowledge, exploration effect thus far. First, pore-scale resolved microfluidic experiments 2D glass cells 3D sintered glass-bead columns were conducted, change pore geometry was observed light microscopy micro X-ray computed tomography, respectively. Second, geometric curves evaluated numerical drainage using pore-network modeling networks extracted from geometries. Finally, both Brooks–Corey Van Genuchten fitted determined compared with porosity average measure geometry’s The pressures increased increasing reduced porosity. For setups, relation parameterized. However, more realistic initial geometries samples, while general patterns pressure may observed, parameterization possible reduction, much higher variability distribution precipitates between experiments. Likely, additional other than will need considered accurately describe porous media.
