| topic |
Polymeric nanofluid SiO2 Nanoparticles Polymer Flooding Transport in porous medium |
| description |
Enhanced oil recovery (EOR) processes were developed as a strategy to extend the productivity of mature reservoirs. Polymer flooding-based HPAM is the EOR process more implemented due to its relatively low cost and operational flexibility; however, the degradation and retention in the reservoir are the main challenges. Several copolymers of polyacrylamide have been proposed to mitigate polymer deficiencies in “hard” conditions; however, these technologies are limited to favorable pricing scenarios. Nanotechnology has attracted widespread interest for use in recovery processes. Nanoparticles (NPs) incorporate new properties into traditional technologies applied in EOR. Polymer-based nanofluids or polymeric nanofluids consist of a combination of nanoparticles with polymeric solutions. Polymeric nanofluids are of great interest because they combine the advantages of inorganic NPs and organic polymers, generating synergy between the best of each of the two materials. Although numerous studies have shown a high potential of polymeric nanofluids, little evidence is available about the stability of polymeric microstructure exposed at thermal degradation, adsorption, and deformations caused by converging-diverging flow in pores. Hence, the main objective of this study is to characterize the rheological behavior of polymeric nanofluids formed by solutions of HPAM and SiO2 nanoparticles under the instability of the microstructure due to thermal degradation and concentration losses. This study provides crucial evidence about the stability of polymeric nanofluids and offers an understanding of its performance in the porous medium. Finally, it opens the landscape about the use of nanofluids in IOR/EOR processes. (Tomado de la fuente) |

Polymer flooding-based HPAM is the EOR process more implemented due to its relatively low cost and operational flexibility; however, the degradation and retention in the reservoir are the main challenges. Several copolymers of polyacrylamide have been proposed to mitigate polymer deficiencies in “hard” conditions; however, these technologies are limited to favorable pricing scenarios. Nanotechnology has attracted widespread interest for use in recovery processes. Nanoparticles (NPs) incorporate new properties into traditional technologies applied in EOR. Polymer-based nanofluids or polymeric nanofluids consist of a combination of nanoparticles with polymeric solutions. Polymeric nanofluids are of great interest because they combine the advantages of inorganic NPs and organic polymers, generating synergy between the best of each of the two materials. Although numerous studies have shown a high potential of polymeric nanofluids, little evidence is available about the stability of polymeric microstructure exposed at thermal degradation, adsorption, and deformations caused by converging-diverging flow in pores. Hence, the main objective of this study is to characterize the rheological behavior of polymeric nanofluids formed by solutions of HPAM and SiO2 nanoparticles under the instability of the microstructure due to thermal degradation and concentration losses. This study provides crucial evidence about the stability of polymeric nanofluids and offers an understanding of its performance in the porous medium. Finally, it opens the landscape about the use of nanofluids in IOR/EOR processes.

La inyección de polímeros basada en HPAM, es el proceso EOR más implementado debido a su costo relativamente bajo y flexibilidad operativa; sin embargo, la degradación y retención en el yacimiento son los principales desafíos. Se han propuesto varios copolímeros de poliacrilamida para mitigar las deficiencias del polímero en condiciones "duras"; sin embargo, estas tecnologías se limitan a escenarios de precios favorables. La nanotecnología ha atraído un interés generalizado para su uso en procesos de recuperación. Las nanopartículas (NP) incorporan nuevas propiedades a las tecnologías tradicionales aplicadas en EOR. Los nanofluidos a base de polímeros o nanofluidos poliméricos consisten en una combinación de nanopartículas con soluciones poliméricas. Los nanofluidos poliméricos son de gran interés porque combinan las ventajas de los NP inorgánicos y los polímeros orgánicos, generando sinergia entre lo mejor de cada uno de los dos materiales. Aunque numerosos estudios han demostrado un alto potencial de los nanofluidos poliméricos, hay poca evidencia disponible sobre la estabilidad de la microestructura polimérica expuesta a la degradación térmica, adsorción y deformaciones causadas por el flujo convergente-divergente en los poros. Por tanto, el objetivo principal de este estudio es caracterizar el comportamiento reológico de los nanofluidos poliméricos formados por soluciones de HPAM y nanopartículas de SiO2, bajo inestabilidad de la microestructura por degradación térmica y pérdidas de concentración. Este estudio proporciona evidencia crucial sobre la estabilidad de los nanofluidos poliméricos y ofrece una comprensión de su desempeño en el medio poroso. Finalmente, abre el panorama sobre el uso de nanofluidos en procesos IOR / EOR.
