“…Regarding the non-uniform distribution size of the gas bubbles, large bubbles have lower pressure than small bubbles which can cause the chemical differences. Therefore, the gas would diffuse into the liquid phase from smaller to larger bubbles that have caused the coalescence [29][30][31][32].…”

As foams are not thermodynamically stable and might be collapsed, foam stability is defined by interfacial properties and bulk solution. In this paper, we investigated foam injection and different salinity brines such as NaCl, CaCl2, KCl, and MgCl2 to measure cumulative oil production. According to the results of this experiment, it is concluded that sequential low-salinity water injections with KCl and foam flooding have provided the highest cumulative oil production in sandstone reservoirs. This issue is related to high wettability changes that had been caused by the KCl. As K+ is a monovalent cation, KCl has the highest wettability changes compared to other saline brines and formation water at 1000 ppm, which is due to the higher wettability changes of potassium (K+) over other saline ions. The interfacial tension for KCl at the lowest value is 1000 ppm and, for MgCl2, has the highest value in this concentration. Moreover, the formation brine, regarding its high value of salty components, had provided lower cumulative oil production before and after foam injection as it had mobilized more in the high permeable zones and, therefore, large volumes of oil would be trapped in the small permeable zones. This was caused by the low wettability alteration of the formation brine. Thereby, formation water flowed in large pores and the oil phase remained in small pores and channels. On the other hand, as foams played a significant role in the mobility control and sweep efficiency, at 2 pore volume, foam increased the pressure drop dramatically after brine injection. Consequently, foam injection after KCl brine injection had the maximum oil recovery factor of 63.14%. MgCl2 and formation brine had 41.21% and 36.51% oil recovery factor.

“…[3][4][5][6] Kamal et al 7 studied the effects of two nanofluid elements, namely motion of Brownian and thermophoresis owing to the nanofluid model. By using the nanofluid model, Asiaei et al 8 tested heat transfer and flow, which can measure the hydromagnetic flow through a stretching sheet (SS). Electrical MHD of nanofluid is used for thermal conductivity testing on a stretching layer in this study.…”

The purpose of the current study is to numerically investigate the effects of shape factors of nanoparticles on natural convection in a fluid saturated porous annulus developed between the elliptical cylinder and square enclosure. A numerical method called the control volume-based finite element method (CVFEM) is implemented for solving the governing equations. The modified flow and thermal structures and corresponding heat transfer features are investigated.Numerical outcomes reveal very good grid independency and excellent agreement with the existing studies. The obtained results convey that at a certain aspect ratio, increment of Rayleigh and Darcy numbers significantly augments the heat transfer and average Nusselt number. Further, enhancement of Rayleigh number increases the velocity of nanofluid while that of aspect ratio of the elliptical cylinder shows the opposite trend.
