The enhancement in surfactant performance at downhole conditions the presence of nanomaterials has fascinated researchers' interest regarding applications nanoparticle-surfactant (NPS) fluids as novel enhanced oil recovery (EOR) techniques. However, governing EOR mechanisms hydrocarbon using NPS solutions are not yet explicit. Pore-scale visualization experiments clarify dominant fluid displacement and trapped/residual mobilization solutions. In this study, influence multiwalled carbon nanotubes (MWCNTs), silicon dioxide (SiO2), aluminum oxide (Al2O3) nanoparticles on properties a conventional (sodium dodecyl benzene sulfonate, SDBS) was investigated via experimental computational dynamics (CFD) simulation approaches. Oil reduced with increased temperatures micromodel heterogeneity. Adding to SDBS decreases fingering channeling effect increases factor. prediction results agreed results, which demonstrated that lowest amount (37.84%) retained after MWCNT-SDBS flooding. within Al2O3-SDBS SiO2-SDBS flooding 58.48 43.42%, respectively. At 80 °C, breakthrough times for MWCNT-SDBS, Al2O3-SDBS, displacing were predicted 32.4, 29.3, 21 h, respectively, whereas water injections similar situations 12.2 6.9 higher time MWCNTs could be attributed their cylindrical shape, promoting orientation liquid–liquid solid–liquid interfaces reduce oil–water interfacial tension contact angles significantly. study highlights prevailing NPS.

The field of microemulsion-assisted conformance improvement technology (ME-CIT) requires workflow planning in order to effectively decrease the water-to-oil ratio during production operations. This article deals with implementation a suitable ME-CIT route via experimental validation. ternary diagram identified different Winsor regions classify phase behavior. aggregation behavior micellar structures ME was studied dynamic light scattering tests. Relative experiments depicted presence I at low salinity upto 20,000 ppm total dissolved salts (TDS) content. At nearly 25,000ppm, this altered into III system. further changed Type 50,000 ppm. surfactant-based microemulsion exhibited favorable time-dependent flow attributes, as evident from observation that steady-state viscosity did not alter markedly elapse time. pseudoplastic rheology has been explained on macroscopic level and micelle morphology microscopic scale two phenomena: electro-shielding deformation. With increasing salinity, versus salt concentration plots revealed unique 'M' shape 7.34 s−1. describes an initial increase, then decreasing trend, followed by increase eventually near-constant content increases further. Porous media were conducted for optimized slug using sandstone core model. A pressure drop reduction water-cut percentages recorded flooding stage laboratory. In summary, proposed methodology contributes toward developing potential microemulsions systems application technology.

Nanofluids, as a novel material for tertiary oil recovery, have shown promising potential in enhancing water flooding efficiency low-permeability reservoirs and increasing recovery rates. However, the risk of particle agglomeration arises when size is too small. Challenges such maintaining dispersion stability, efficient long-distance transportation nanofluids, preventing retention emerged key obstacles hindering widespread adoption large-scale implementation nanoflooding technology various reservoir conditions. With issues poor nanoparticle costly reprocessing, limited fluid compatibility addressed, nano-SiO2 particles with average sizes 45, 170, 625 nm were synthesized using an enhanced control technique based on Stöber method. The impact these different dispersion, emulsion oil–water interfacial tension (IFT), viscosity reduction before after modification fatty alcohol polyoxyethylene ether (AEO) investigated. findings demonstrate that modified exhibits stability reduced IFT. At primary AEO concentration 0.25 wt %, micellar structure formation synergizes SiO2 to achieve optimal IFT reduction. Smaller are more amenable surface exhibit superior adsorption capacity at interface compared larger particles, facilitating interaction asphaltene aggregates and, thereby, crude flowability. In study, 170 nanosized demonstrated substantial effect, apparent rate 95.3% 0.0025 % + under test conditions 45 °C 5 s–1, indicating significant effect. This research introduces concept designing nanofluids repel tight reservoirs, establishing repulsion system. These not only advance theoretical understanding but also contribute development conventional unconventional gas fields, including deep shale ultraheavy thick reservoirs.

The application of surfactant flooding for enhanced oil recovery (EOR) promotes hydrocarbon through reduction oil-water interfacial tension and alteration oil-wet rock wettability into the water-wet state. Unfortunately, depletion in porous media, due to molecule adsorption retention, adversely affects recovery, thus increasing cost process. Chemical-based materials are normally used as inhibitors or sacrificial agents minimize adsorption, but they quite expensive not environmentally friendly. Plant-based (henna extracts) far more sustainable because obtained from natural sources. However, there is limited research on henna extracts reduce dynamic media improve such media. Thus, were introduced an eco-friendly low-cost agent minimizing static sodium dodecyl sulfate (SDS) onto quartz sand this study. Results showed that extent was inversely proportional extract concentration, surface a multilayer followed Freundlich isotherm model. Precisely, range 3.12-4.48 mg/g (for adsorption) 5.49-6.73 adsorption), whereas SDS 2.11 4.79 at conditions, respectively. In presence 8000 mg/L extract, significantly reduced by 64 82%, At same residual increased 9.2% over normal flooding. study suggests use during could result molecules sand, promoting sandstone formations.
