Viscoelastic displacement mechanism of fluorescent polymer microspheres based on macroscopic and microscopic displacement experiments

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(4)

Published: April 1, 2025

Polymer microspheres represent a novel oil displacement agent that has demonstrated significant efficacy in oilfields. Recent research indicates the viscoelastic properties of polymer are crucial for displacement. To further elucidate mechanism, series fluorescent microspheres, P(AM-BM-AA-[Br−Flu]), with varying elasticity were synthesized via inverse suspension polymerization, incorporating monomers derived from fluorescein (Br−Flu). The micromorphology and systematically characterized using an infrared spectrometer, scanning electron microscope, inverted fluorescence laser particle size analyzer, rheometer. Through microscopic macroscopic experiments, along microsphere concentration tests, mechanism was investigated. results indicate P(AM-BM-AA-[Br−Flu]) exhibiting green successfully synthesized. By adjusting crosslinker concentration, different elasticities produced. During process, governs their migration mode within pore throats. Microspheres higher exhibit greater sweep efficiency. pushing carrying effect on residual droplets, positive pressure breakthrough resulting trapping, blind-end collectively enhance efficiency microspheres. From force analysis perspective, plays pivotal role improving both These findings provide experimental support understanding mechanisms developing new microsphere-based agents.

Numerical modeling of asphaltene deposition in CO2-flooded porous media

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(1)

Published: Jan. 1, 2025

CO2 flooding disrupts asphaltene balance, causing deposition and reservoir damage. Most models lack core verification, resulting in inaccurate predictions of performance. The Discrete Phase Model (DPM) Volume model for characterizing during was established by coupling Fluid with DPM, which simulates the complex interaction between CO2-flooded crude oil flow dynamics. Key factors such as mole fraction, displacement velocity, viscosity, density, particle size on deposition, well impact porosity permeability degradation, were comprehensively examined. findings show that increasing fraction from 0.2 to 1 enhances rate 53.6% damages 2.4 5.78, respectively. Raising injection velocity rises 0.006 0.016 m/s reduces 17.97%, damage factor drops 1.981 1.075 decreases 3.926 1.556. Higher viscosity significantly both related damage, while density diameter correlate greater rates. Asphaltene particles accumulate within throats porous media dispersed particulates, they densely pack pores. Gray correlation analysis reveals exhibits highest relationship extent pore impairment. This study understanding dynamics mechanisms CO2-flooded.

Effect of Amphiphilic Silicon Quantum Dots on Foam Stability and Their Potential in Enhanced Oil Recovery

Energy & Fuels, Journal Year: 2025, Volume and Issue: 39(9), P. 4227 - 4237

Published: Feb. 24, 2025

Nowadays, novel silicon quantum dots (SiQDs) are applied in various aspects of the petroleum industry, especially enhanced oil recovery (EOR). Herein, amphiphilic (ASiQDs) were synthesized to improve stability foam formed by nonionic surfactant polyethylene glycol monoisodecyl ether (PMIE). The greater and resistance stabilized 0.05% PMIE-0.1% ASiQD system compared other systems (including pure PMIE conventional silica nanoparticles (SiNPs)–PMIE systems) confirmed relative volume measurement, half-life Turbiscan Laboratories expert analysis, observation morphology. Based on dynamic surface tension modulus measurements, promising was attributed rigid film generated largely adsorbed ASiQDs with tiny size moderate hydrophobicity. more intensive electrostatic repulsion among smaller bubbles, significantly preventing coalescence. Finally, sandpack flooding results suggested PMIE-0.1%ASiQD could efficiently plug high permeability pore throats evidently 21.2%. report employed efficiency for EOR.
