“…Ultrasound also showed greater efficiency under high intensity of ultrasound and for high concentration of surfactant that is above the critical micelle concentration (CMC). Another study was a visualization experiment conducted using 2D glass micromodel exposed to ultrasonic energy under 40 kHz and 500 W to observe the difference between intermittent and continuous sonication on oil recovery [5]. The result revealed that intermittent sonication recovered more oil when compared to continuous sonication during ultrasonic operation and high intensity of ultrasound performed better for heavy oil.…”

“…Fluid displacement in porous media was controlled by viscous, capillary, hydrodynamic and gravity forces. A ratio between any two of these forces can be expressed as a dimensionless number [54]. Dimensionless numbers can be used to quantify the effect of these controlling forces in EOR process.…”

Ascorbic acid was used for the first time to synthesize cellulose nanoparticles (CNP) extracted from okra mucilage. The physical properties of the CNP including their size distribution, and crystalline structures were investigated. The rheological properties of the cellulose nanofluid (CNF) were compared with the bulk okra mucilage and commercial polymer xanthan. The interfacial properties of the CNF at the interface of oil-water (O/W) system were investigated at different concentrations and temperatures. The effects of the interaction between the electrolyte and ultrasonic were determined. Core flooding experiment was conducted at reservoir condition to justify the effect of the flow behaviour and disperse phase behaviour of CNF on additional oil recovery. The performance of the CNF was compared to conventional EOR chemical. The combined method of ultrasonic, weak-acid hydrolysis and nanoprecipitation were effective in producing spherical and polygonal nanoparticles with a mean diameter of 100 nm, increased yield of 51% and preserved crystallinity respectively. The zeta potential result shows that the CNF was stable, and the surface charge signifies long term stability of the fluid when injected into oil field reservoirs. The CNF, okra and xanthan exhibited shear-thinning and pseudoplastic behaviour. The IFT decreased with increase in concentration of CNF, electrolyte and temperature. The pressure drop data confirmed the stability of CNF at 120°C and the formation of oil bank was enough to increase the oil recovery by 20%. CNF was found to be very effective in mobilizing residual oil at high-temperature high-pressure (HTHP) reservoir condition. The energy and cost estimations have shown that investing in ultrasonic-assisted weak-acid hydrolysis is easier, cost-effective, and can reduce energy consumption making the method economically advantageous compared to conventional methods.

“…For instance, the ultrasonic wave is able to effectively reduce the viscosity of heavy oil through aquathermolysis reaction, but such effect becomes pale in the light oil stored in low-permeability reservoirs due to the low viscosity in its nature [28] , [29] . Recently, the ultrasonic wave has also been proved to change the relative permeability of oil in low-permeability reservoirs [30] , [31] , [16] , [32] , [33] , [34] , [35] . In addition, with high energies, the ultrasonic waves may also change the microstructure of cores [36] .…”
