“…Then, the model is verified under the condition of two‐phase flow, where the solute advection is active. The inaccurate modeling of solute advection can cause the artificial (unphysical) mass transfer near the interface (Maes & Soulaine, 2018, 2020). The artificial mass transfer is induced when the solute advection is not consistent with fluids motion.…”

“…The PFM, solving the coupled Cahn‐Hilliard and Navier‐Stokes equations, is already well developed and numerous simulation studies were performed addressing the two‐phase flow system (Akhlaghi Amiri & Hamouda, 2013; Alpak et al., 2016; Jacqmin, 1999; Yue et al., 2004, 2006). In addition, numerous recent studies have applied PFM to study various subsurface flow problems related to fluid viscosity, capillarity, temperature, wettability, heterogeneity, and fractures (Akhlaghi Amiri & Hamouda, 2013, 2014; Basirat et al., 2017; Rokhforouz & Akhlaghi Amiri, 2017, 2018). To our knowledge, PFM has not yet been applied to study reactive transport for two phase flow in porous media.…”

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)

“…Because pore‐scale events in spontaneous imbibition, particularly cocurrent spontaneous imbibition, are so quick that current imaging techniques may not capture them, the pore‐scale modeling will be tremendously beneficial. Previous pore‐scale modeling of spontaneous imbibition have been limited to synthetic 2‐D porous media or a porous domain smaller than the REV size (Bakhshian, Rabbani, et al., 2020; Diao et al., 2021; Liu et al., 2020; Rokhforouz & Akhlaghi Amiri, 2018; Zheng et al., 2021). As a result, the obtained pore‐scale information was not upscaled to Darcy‐scale capillary pressure and relative permeability.…”

“…Two-phase flow in fractured rocks is relevant to various application, ranging from geothermal energy (Babaei and Nick 2019;Erfani et al 2019), groundwater contamination (Gleeson et al 2009;Sebben et al 2015;Aminnaji et al 2019;Aljuboori et al 2019;Dejam 2019), carbon capturing and storage (Emami-Meybodi et al 2015;Babaei and Islam 2018;Erfani Gahrooei and Joonaki 2018;Dejam and Hassanzadeh 2018;Erfani et al 2020;An et al 2020b;Ershadnia et al 2020), and soil salinization (Weisbrod and Dragila 2006) to enhanced hydrocarbon recovery (Farajzadeh et al 2012;Rokhforouz and Akhlaghi Amiri 2017;Rokhforouz and Amiri 2018;Bakhshi et al 2018;Rabbani et al 2020a;Chen et al 2020;An et al 2020a). The complexity of the fluid flow in highly heterogeneous rocks is caused by the notion that the fluid flows in two different media, matrix block and fracture, which separates the fluids into flowing and stagnant regions due to property contrast (Erfani et al 2019;Hasan et al 2019;Soltanian et al 2019;An et al 2020c;Aziz et al 2020;Rabbani et al 2020b;Hasan et al 2020).…”

Experimental and Modelling Study of Gravity Drainage in a Three-Block System

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.
