“…A small insignificant peak found around 28‐C(002) and another peak at 2θ = 44‐C(100) are certifying the presence of SWCNTs. These peaks observed for CNTs are close to that of graphite due to intrinsic nature of both graphite and CNTs 56–58 . That also confirms the structure of synthesized nanofiller.…”

Manganese nanoferrites are decorated over single‐wall carbon nanotubes using in situ co‐precipitation technique to incorporate into cellulose acetate (CA) polymer in order to prepare nanocomposite membranes for salt rejection and desalination purpose. The microstructural study reveals the pore size of the synthesized membranes from 5 nm to 0.20 μm depending upon the loading concentration of the impregnated nanocomposite tubes. Fourier transform infrared (FTIR) and X‐ray diffraction (XRD) patterns of the synthesized membranes delineate the presence of decorated nanotubes in the host polymer matrix. Thermal degradation study proclaims the thermal endurance enhancement with increasing nanotubes concentration in the polymer matrix. Flux rate of the deionized (DI) water through the prepared membranes decreases with increasing nano‐filler concentration while this impact is observed inverse in salt rejection study of the aluminum sulphate (Al2(SO4)3) and zinc sulphate (ZnSO4) solutions due to the transformation of microporosity to nanoporosity with increasing composite tubes dosing into the host CA polymer.

“…The increasing energy demand for domestic and industrial uses led to the application of enhanced oil recovery (EOR) to extract residual oil after primary and secondary methods (Afolabi and Yusuf 2019;Hendraningrat and Torsaeter 2016;Soleimani et al 2016a, b;Hamza et al 2017a, b). In most EOR technologies, such as surfactant flooding, polymer-surfactant flooding and foam flooding, surfactants play unprecedented roles that include reduction in interfacial tension and sometimes in gas mobility control (Moradi et al 2019;Hanamertani et al 2018;Dang et al 2017;Kamal et al 2017;Soleimani et al 2015). A major technical challenge during chemical and gas flooding that received widespread interests is the effect of viscous fingering and early gas breakthrough (Jia et al 2017;Xu et al 2016;Hendraningrat and Zhang 2015).…”

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.

“…Laboratory reports show that nanofluids increases oil recovery; the degree of increase depends on the properties of the nanofluids such as nanoparticles size, concentration and material types, and the type of fluid [59][60][61][62][63][64][65][66]. Nanoparticles in water-based nanofluid alter the wettability of the reservoir from oil-wet to water-wet [67].…”

Enhanced Oil Recovery Practices: Global Trend, Nigeria’s Present Status, Prospects and Challenges

Enhanced oil recovery (EOR) techniques are considered due to unimpressive oil recovery, limited oil reserves, and non-applicability of primary recovery methods in some (heavy oil) fields. In Nigeria, preparation is in gear towards implementing EOR projects. This paper therefore reviews the global trend of EOR practices and discusses Nigeria’s present status, prospects, and challenges. Most EOR projects are employed in sandstone (high permeability) reservoirs; hence based on lithological considerations, all EOR methods are feasible in Nigeria. However, miscible hydrocarbon gas injection is found to be a very good EOR choice because it would drastically reduce the uneconomical practice of gas flaring; besides, transportation of carbon dioxide (CO2) and flue gas is virtually non-existent in Nigeria. Chemical (especially surfactant) flooding is costly; hence it would be feasible in Nigeria if oil price is high. At present, cost implications of heat treatment facilities may be an impedance to implementing thermal EOR for heavy oil in Nigeria. Though microbial EOR is the cheapest, it is not favorable in high temperature (above 85 oC), high salinity (above 100,000 ppm) and deeper (beyond 3,500m) reservoirs. For EOR practices to thrive in Nigeria, there should be an extensive economic evaluation and forecasting, effective research and development, effective training of technical staff for proper operation, surveillance and maintenance of EOR projects, implementation of health, safety and environmental (HSE) guidelines, low inflation rates, low interest rates on loans, general price stability, favorable tax policy, low import duties on machineries and equipment used for EOR, modified private market decisions and encouraging legal and regulatory framework.
