“…Consequently, the ∆p buildup improvement due to the presence of the NPs is improved by about 83% relative to the precursor MFomax foam. This finding is in accordance with the work in (Farhadi et al 2016), where the authors reported that foamcontaining NPs control gas mobility better than its precursor surfactant foam. The effects of NPs blend in surfactant recipes have also been reported in (Vatanparast et al 2017;Hamza et al 2017a, b;Farhadi et al 2016; Soleimani et al Li et al 2013).…”

The examination of the permeability impairment shows that the injection of the NF reduced the core's permeability by a factor of 8% which is relatively low and will not affect the reservoir productivity.…”

In this study, an industrial-based surfactant known as MFomax surfactant has been modified with unfunctionalized and silanefunctionalized silica nanoparticles (NPs) to select the high viscous nano-fluid (NF) for generation of in situ foam to assess the differential pressure buildup (∆p) behavior in the porous media. Different weight concentrations of NPs and MFomax from 0.1 to 0.5% were studied using Design Expert Software to generate full matrix design of NF formulations. The viscosity data were analyzed with the aid of response surface analytical tool to investigate the response of NPs loading on the NF viscosity for optimization. The microstructural properties of the NFs were characterized using spectroscopic equipment. Subsequently, the high viscous NF was selected to generate in situ foam in comparison with the precursor MFomax foam for ∆p buildup assessment at 110 °C and 2023 psi in the native reservoir core. Results have shown that both the silica NPs could significantly improve the MFomax viscosity; however, the silane-functionalized silica NPs have more effect to improve the viscosity and other microstructural properties than the unfunctionalized NPs, and thus, they were selected for further experimental studies. The coreflood ∆p buildup assessment shows that NF foam built more ∆p having average value of 46 psi against 25 psi observed in the case of the precursor MFomax foam. Thus, this study demonstrates that functionalized silica NPs could improve the MFomax viscosity and eventually generates high ∆p buildup at high-temperature high-pressure conditions.

“…Farhadi et al examined the stability and mobility control of a silica-stabilized CO 2 foam system. It was proved that this system produced uniform and small foams with high apparent viscosity compared to the surfactant-only system Recent Insights in Petroleum Science and Engineering [31]. Hydrophobic silica was also adopted to stabilize a conventional foam system, and the resultant foam system was more rough than that of PEG-coated nanosilica-stabilized foam [32].…”

As a result of the ever-increasing global energy demand coupled with the rapid decline of the oil production, the games of enhanced oil recovery (EOR) are played in many oilfields worldwide especially in China. It was reported that EOR jobs produced 45.1 × 10 4 m 3 /d of oil production rate in 2014 all over the world, proving the significance of these jobs.Due to the complex geology, chemical enhanced oil recovery (C-EOR) methods are considered the predominant technology in China and takes nearly 86% of the total EOR projects currently. This fact motivates us to develop novel and more advanced C-EOR methods for different geological types of Chinese reservoirs such as high temperature and pressure, ultralow permeability, heavy oil reservoirs, etc. Through 20 years' efforts, many advantageous C-EOR methods have been successfully developed in our group and tested in oilfields such as stabilized foam injection, nanofluid flooding, functional polymer flooding, etc. Herein, this chapter summarized the latest experimental results of three representative C-EOR methods. More attentions were given to the relationship between bulk properties and flow behaviors in porous media. The lessons learned from our research in C-EOR were also discussed in this chapter.Keywords: enhanced oil recovery, chemical flooding, innovative EOR, nanofluid, polymer microsphere, enhanced foam Nanofluid floodingTo date, hydrolyzed polyacrylamide (HPAM) is still the most widely used polymer due to its availability in large quantities with customizable properties (molecular weight, hydrolysis degree, etc.) and low manufacturing cost. However, acrylamide-based polymers are susceptible to chemical, mechanical, thermal, and microbial degradations [1]. In addition, the acrylamide monomers place © 2018 The Author(s). Licensee InTech.

Nanofluids, which are obtained through dispersing nanoparticles in the base fluids, are attracting research attentions. The nanofluids usually exhibit high thermal conductivities, which are significant to the development of energy, and have been widely used in drug delivery solar cells, lipase immobilization, soil remediation, lubrication, and hydraulic fracturing of gas and oil. In addition, nanofluids have been introduced to the enhanced oil recovery (EOR) area due to their unique thermal properties and large surface area [4][5][6][7][8]. Many works have been done to study the EOR performance of nanofluids composed of different nanoparticles. Hendraningrat et al. evaluated the displacement efficiency of the nanofluid. They claimed that the nanofluid increased the oil recovery by 7-14.3% and the optimum concentration was 0.05 wt% for water-wet core [9,10]. The stability of nanofluids was considered as an imp...

“…Foam stability depends on various parameters such as surface tension, temperature, rheological properties (surface viscosity and elasticity), liquid composition, pH, NP's concentration, presence of volatile solvent etc. Overall, the foaming ability and foam stability are associated to (i) the presence of the surfactant in the liquid, (ii) the subsistence of dynamic conditions, (iii) high interfacial energy, and (iv) the rheological properties of materials, interfaces, and their exchanges in foam films [1][2][3][4][5][6][7].…”

“…The volume of the foam produced and the life time of either the entire or half the height of the foam formed is measured in this method [2], [10]. A surfactant molecule with rather low energy lies at the gas-liquid interface and reduces the surface tension [7]. Foam shows various applications in an industry, it used to overcome gas mobility challenges in petroleum reservoirs.…”

The purpose of this research work was to study the stability of static foam and the role of silica and TiO 2 nanoparticles (NP's) in foam stability of nonionic surfactant Tween-20. Foam stability and Half-life of the foam were investigated and compared with and without using silica and TiO 2 NP's. Combine effects of NP's and ethanol on foam stability was also studied. For surfactant concentration 3 g L-1 ; Half-life was 120 min for silica NP's and for TiO 2 NP's it was 78.2min.
