Understanding multi-phase, multi-component, reactive flow and transport in porous media is important for a wide range of scientific and engineering applications. Such applications comprise for example the geological storage of carbon dioxide, groundwater remediation, enhanced oil recovery, material manufacturing, and so on (Scheer et al., 2021). In this context, the quantification of the magnitude of the Fluid-Fluid Interfacial Area (FIFA) is essential for studying reactive multi-phase flow and transport in porous materials (Hassanizadeh & Gray, 1990;Miller et al., 1990;Reeves & Celia, 1996). For example, in geological storage of CO 2 , both the rate of CO 2 dissolution in brine and the extent of the residual trapping are determined by the FIFA (Tatomir et al., 2018). Existing techniques for FIFA measurement mainly comprise tracer techniques, e.g., Interfacial Partitioning Tracer Tests (IPTT)

“…We assumed a 2D porous medium from a thin slice of Berea sandstone, first presented by Keller et al (1997) for a micro-model experiment. The geometry has already been used as the computational domain in Basirat et al (2017) and Rokhforouz and Akhlaghi Amiri (2019). The domain measures 660 × 320 μm in size.…”

“…They aimed to investigate the adequacy of COMSOL in the modelling of unconventional reservoirs and showed that many important areas of EOR methods can be investigated using this package. Finally, they concluded that, although the computational cost and performance of the commercial packages, like CMG, is still better than COMSOL, due to the high variability and flexibility, COMSOL can be used for phenomenological investigation of new EOR methods in pore to core scale (Bogdanov et al 2007;Rokhforouz and Amiri 2019). Bjørnarå and Aker (2008) implemented two-phase flow equations of porous media in COMSOL, which can be very complex depending on the introduced assumptions.…”

Gravity drainage is known as the controlling mechanism of oil recovery in naturally fractured reservoirs. The efficiency of this mechanism is controlled by block-to-block interactions through capillary continuity and/or reinfiltration processes. In this study, at first, several free-fall gravity drainage experiments were conducted on a well-designed three-block apparatus and the role of tilt angle, spacers’ permeability, wettability and effective contact area (representing a different status of the block-to-block interactions between matrix blocks) on the recovery efficiency were investigated. Then, an experimental-based numerical model of free-fall gravity drainage process was developed, validated and used for monitoring the saturation profiles along with the matrix blocks. Results showed that gas wetting condition of horizontal fracture weakens the capillary continuity and in consequence decreases the recovery factor in comparison with the original liquid wetting condition. Moreover, higher spacers’ permeability increases oil recovery at early times, while it decreases the ultimate recovery factor. Tilt angle from the vertical axis decreases recovery factor, due to greater connectivity of matrix blocks to vertical fracture and consequent channelling. Decreasing horizontal fracture aperture decreases recovery at early times but increases the ultimate recovery due to a greater extent of capillary continuity between the adjacent blocks. Well match observed between the numerical model results and the experimental data of oil recovery makes the COMSOL multiphysics model attractive for application in multi-blocks fractured systems considering block-to-block interactions. The findings of this research improve our understanding of the role of different fracture properties on the block-to-block interactions and how they change the ultimate recovery of a multi-block system.
