“…The apparent viscosity increased until a peak of approximately 9 cP was reached, before decreasing and indication of foam coalescence. The reduction in water saturation and development of continuous CO 2 flow paths not impeded by lamella caused the foam to dry out (Farajzadeh et al, 2015;Benali et al, 2022). After several PVs injected, the apparent viscosity remained slightly higher than for the baseline experiment indicating decreased CO 2 mobility due to foam generation.…”

The efficiency of CO 2 injection for enhanced oil recovery and carbon storage is limited by severe viscosity and density differences between CO 2 and reservoir fluids and reservoir heterogeneity. In-situ generation of CO 2 foam can improve the mobility ratio to increase oil displacement and CO 2 storage capacity in geological formations. The aim of this work was to investigate the ability of CO 2 foam to increase oil production and associated CO 2 storage potential, compared to other CO 2 injection methods, in experiments that deploy field-scale injection strategies. Additionally, the effect of oil on CO 2 foam generation and stability was investigated. Three different injection strategies were implemented in the CO 2 enhanced oil recovery and associated CO 2 storage experiments: pure CO 2 injection, water-alternating-gas and surfactant-alternating-gas. Foam generation during surfactantalternating-gas experiments showed reduced CO 2 mobility compared to water-alternatinggas and pure CO 2 injections indicated by the increase in apparent viscosity. CO 2 foam increased oil recovery by 50% compared to pure CO 2 injection and 25% compared to water-alternating-gas. In addition, CO 2 storage capacity increased from 12% during pure CO 2 injection up to 70% during surfactant-alternating-gas injections. Experiments performed at high oil saturations revealed a delay in foam generation until a critical oil saturation of 30% was reached. Oil/water emulsions in addition to CO 2 foam generation contributed to CO 2 mobility reduction resulting in increased CO 2 storage capacity with foam.

“…Constant CO 2 injection caused foam to agglomerate, creating extensive gas channels transverse to the direction of flow that weakened the apparent viscosity of the foam. 47,48 In addition, the analysis indicated that the stable CO 2 foam could be effectively produced by directly co-injecting CO 2 and NP dispersion into the cores of the materials. When it came to the production of stabilized CO 2 foam, the value of the crucial share rate, both with and without NPs, was the most important aspect.…”

Global demand for energy is increasing day by day rapidly as a result of the population, industrial, and economic growth of developing countries, especially in emerging market economies. Hence, to meet this growing and continuing global crude oil demand, innovative enhanced oil recovery (EOR) techniques are required to emerge, and currently, implemented techniques need to be revisited and optimized to recover more residual oil trapped in the reservoirs. Among different chemicals, foam has good mobility control in the oil recovery method. Nowadays, the study on the stability of foam is an utmost interest for petroleum engineers to find a way to obtain stable foam for application in EOR. In this review, the basics of foam and its preparations, properties, application, and some special applications mainly in the oil industry have been depicted to convey an idea of the degree of foam research in EOR. Basically, this review will provide a detailed discussion on the applications of foam in oil recovery and some short ideas that can be applied in the near future for nanoparticle (NP)-assisted stable CO2 foam flooding in EOR. Increasing the NP concentration initially improved foam stability because a higher number of NPs participated in strengthening the gas bubble and initially increased oil recovery as a result of the formation of more stable foam. The polymer-coated, nanoclay–surfactant-stabilized foam and surface-modified silica nanoparticles have exceptional foaming ability and foam stability at high temperatures, making them suitable for the production from heavy oil reservoirs. Some other nanoparticles, like Al2O3, ZrO2, TiO2, Fe2O3, and NiO, have also been used for enhancing foam stability by preventing liquid drainage from lamella. Also, NP-stabilized CO2 foam flooding can enhance oil recovery by 10–15% after secondary recovery by creating a more homogeneous gas front for better mobility control.

Microfluidics presents an unprecedented opportunity to understand fluid properties and phase measurements at extreme conditions relevant to energy applications. Since the 1950s, when a simple micromodel system was built to visualize fluid behavior in porous media, microfluidics has matured and has been adapted to help address the biggest fluid challenges within the energy industry. Modern microfluidic systems are robust at high temperatures and pressures and can provide phase property analyses competitive with the most established bulk methods. In contrast to bulk methods, microfluidic approaches offer advantages in speed, cost, control, and sample size. Here, we review and highlight the past and present of microfluidic-based fluid analysis and look ahead to future applications and the opportunity presented by the energy sector transition ahead.
