“…The wetting phase film gets thicker, and the continuity of the nonwetting phase is eventually broken. 8,31 The capillary pressure that contributes to snap-off 102 can be expressed by eq 12: P r (cos sin ) s = (12) where P s is the capillary pressure for snap-off.…”

“…This method is not repeatable and thus is inadequate for real-time flow observations . Traditional visualization techniques for pore-scale displacement dynamics, such as the constricted glass capillaries, glass bead packs, glass model pore system, − and artificial micromodels − (glass or other transparent material), have been used to represent the rock matrix. Some researchers built micromodels with a thin layer of rock samples constrained by two glass plates .…”

Microcomputed tomography (micro-CT) is a nondestructive visualization tool that can capture real-time in situ multiphase flow dynamics inside the opaque rock. It is a promising technique for deepening the understanding of the microscopic displacement mechanisms of water and gas flooding. By applying micro-CT, the real-time fluid and interface distribution can be obtained in the form of 3D visualizations. Pore-scale information such as in situ contact angle, interfacial tension, capillary pressure, and residual oil distribution can be conveniently obtained from the 3D model. Furthermore, as a nondestructive technique, micro-CT makes it possible to record the previously mentioned information along with time without disturbing the multiphase flow system, thus enabling the study of the multiphase flow system dynamically. This capability of micro-CT largely helps understand the microscopic displacement mechanisms, which is crucial for secondary and tertiary oil recovery. This review work introduces micro-CT and its applications in core flooding systems. It summarizes the information which can be determined quantitatively based on the 3D model obtained from micro-CT data. It also summarizes recent research findings inspired by micro-CT applications, including conclusions about the multiphase flow system, mechanism understandings of the pore-scale dynamics, and applications in flooding, and CO2 sequestration.

“…The small size of the aphron's bubbles provide them with high inter-facial areas that makes them amenable to being pumped, in a similar way to water, without risk of collapse [3]. A broad range of novel technologies and their applications, introduced in recent years, play a substantial role in improving standards of living and access to energy and resources, such as oil pretreatment [4,5], biofuels [6][7][8][9], corrosion [10,11], carbon dioxide [12][13][14], wastewater treatments [15,16], flow in porous media [17][18][19], bioresource technology [6][7][8]13,15,[20][21][22][23][24], Enhanced Oil Recovery [25][26][27][28][29][30]. CGA-based fluid technologies are being deployed with success in horizontal and high-angle wellbore trajectories in highly pressuredepleted reservoirs [31].…”

<p>At-balance drilling technology applications demand the use of special drilling fluids, For example, colloidal-gas-aphron fluids (CGA) are being deployed to good effect in drilling applications. GCA-based drilling fluids have physico-chemical attributes that enable them to usefully influence and control downhole conditions. Furthermore, the involvement of nanoparticles and surfactants in their formulations enhances the performance and stability of CGA suspensions. This study describes the stability analysis, rheological characterization and filtration properties of CGA suspensions for the novel eco-friendly biosurfactant, <i>Olea europaea </i>(common olive), in presence of nanoparticles. Filtration and stability analysis was performed using API filtration tests and the static drain-rate technique, respectively. Several rheological models are developed to quantify the shear-flow characteristics of Olea-nano-based CGA suspensions. The Herschel-Bulkley and the Mizhari-Berk models provided the best shear-flow prediction accuracy with very small error values in terms of root mean squared error. Results reveal that the introduction of the biosurfactant improves the CGA-based fluid properties. Moreover, the observed improvements are further enhanced by including silica and fumed silica nanoparticles in the formulations. The Olea-nano-CGA-based fluids exhibit non-Newtonian behavior. The rheology of CGA-based fluids depends upon base-fluid viscosity, as it does in aqueous polymeric foams. The optimum concentrations of nanoparticles in Olea-nano-based CGA fluids is identified to provide them with fluid-flow indices ranging between 0.15 and 0.30. </p>

Solar energy is commercially exploited to provide benefits in the form of various products and capabilities applying a range of technologies. Electricity generation is achieved either directly from photovoltaic cells made of various materials or indirectly through the steam production from concentrating solar thermal systems. Whereas solar thermal power generation requires large scale plants, photovoltaic systems can be large or small in scale and building integrated, if required. Both types of generation can be standalone or connected to power grids. Solar energy is also extensively used for water and space heating, cooling and drying purposes. It can also be stored and/or transformed into a range of clean fuels and contributes energy to the manufacture of various energy-intensive products. The research into the artificial photosynthetic synthesis of biofuels although encouraging is, however, yet to be achieved commercially exploited on a large scale. Much scope remains for innovative technology breakthroughs to further improve the efficiency and uptake of all the solar energy technologies currently exploited or under investigation. Policy frameworks, renewable portfolio standards, feed-in tariffs and net-metering play an important and ongoing role in promoting the uptake of photovoltaics in particular.
