“…However, the effect is negligible in high-permeability media, suggesting the nanocellulose hydrodynamic radius as a critical factor in the performance of the material for EOR applications. 88 Similarly, Liu et al found improved salt and thermal tolerance in TEMPO-oxidized CNFs modified by simultaneous grafting of N,N-dimethylacrylamide, and butyl acrylate by ceric-ammonium-nitrate-induced radical polymerization. 89 The viscosity of modified CNF aqueous dispersions (0.3 wt %) increased as a result of hydrophobic entanglement between the twin tails of poly(dimethylacrylamide) (PDMA) and polybutyacrylate (PBA) moieties on the surface of cellulose.…”

“…Nanocellulose surface modification, by grafting residues that confer amphiphilic properties to the polymer, is a plausible course of action for rock wettability alteration. Along these lines, a nanofluid containing 0.3% CNF modified with poly(2-acrylamido-2-methylpropane sulfonic acid) [poly(AMPS)] was found to efficiently adsorb onto sandstone, inverting the surface wettability from oil-wet to water-wet. , The grafting of poly(AMPS) increased the salt tolerance of CNF by preventing the collapse of the electric double layer at the surface of the material. Poly(AMPS)–CNF simultaneously promotes emulsification, dragging, and surface wettability changes, increasing oil recovery up to 3.53–6.92% of the OOIP in displacement experiments.…”

The increasing energy demand worldwide pushes the exploration of new and efficient ways to improve crude oil recovery and processing. From a chemical perspective, the petroleum industry relies on a wide range of specialty additives to provide the necessary fluid qualities for up-, mid-, and downstream operations. Currently, most of these compounds come from synthetic sources. However, attention is steadily turning to highperformance new materials derived from natural sources to improve the efficiency and productivity of the petroleum industry while reducing its environmental impacts. Cellulose is an abundant, renewable, and biodegradable material with outstanding chemical versatility. Cellulose structural modifications result in numerous products, with some as old as paper, textiles, explosives, and texturizing agents and others as new as functional nanostructures. This minireview focuses on nanocellulose-based materials as high-performance agents for enhanced oil recovery and emulsion stabilization/destabilization in the petroleum industry.

“…Experiments using surface-functionalized nanocellulose showed that the particles contributed to a 3–17% increase in oil recovery when injected after water flooding. From microfluidic experiments using the same particles, three main oil recovery mechanisms were discovered: emulsification, dragging, and wettability alteration [ 16 ]. Emulsification was also one of the main findings from a previous study Wei et al [ 15 ] conducted.…”

Cellulose nanocrystals (CNCs) and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (T-CNFs) were tested as enhanced oil recovery (EOR) agents through core floods and microfluidic experiments. Both particles were mixed with low salinity water (LSW). The core floods were grouped into three parts based on the research objectives. In Part 1, secondary core flood using CNCs was compared to regular water flooding at fixed conditions, by reusing the same core plug to maintain the same pore structure. CNCs produced 5.8% of original oil in place (OOIP) more oil than LSW. For Part 2, the effect of injection scheme, temperature, and rock wettability was investigated using CNCs. The same trend was observed for the secondary floods, with CNCs performing better than their parallel experiment using LSW. Furthermore, the particles seemed to perform better under mixed-wet conditions. Additional oil (2.9–15.7% of OOIP) was produced when CNCs were injected as a tertiary EOR agent, with more incremental oil produced at high temperature. In the final part, the effect of particle type was studied. T-CNFs produced significantly more oil compared to CNCs. However, the injection of T-CNF particles resulted in a steep increase in pressure, which never stabilized. Furthermore, a filter cake was observed at the core face after the experiment was completed. Microfluidic experiments showed that both T-CNF and CNC nanofluids led to a better sweep efficiency compared to low salinity water flooding. T-CNF particles showed the ability to enhance the oil recovery by breaking up events and reducing the trapping efficiency of the porous medium. A higher flow rate resulted in lower oil recovery factors and higher remaining oil connectivity. Contact angle and interfacial tension measurements were conducted to understand the oil recovery mechanisms. CNCs altered the interfacial tension the most, while T-CNFs had the largest effect on the contact angle. However, the changes were not significant enough for them to be considered primary EOR mechanisms.

“…Compared with these technologies, it looks promising to use a polymeric nanoparticle suspension as a selective water-shutoff-plugging agent for conformance control treatments in heterogeneous reservoirs. Injecting a large volume of polymeric nanoparticle suspension to plug high-permeability zones and improve oil recovery has become an attractive technology in recent years [26,27,28,29,30]. Polymeric nanoparticle suspension is a system in which polymeric nanoparticles are dispersed in aqueous solution.…”

Enhanced Oil Recovery by a Suspension of Core-Shell Polymeric Nanoparticles in Heterogeneous Low-Permeability Oil Reservoirs

et al. 2019

Polymeric nanoparticle suspension is a newly developed oil-displacing agent for enhanced oil recovery (EOR) in low-permeability reservoirs. In this work, SiO2/P(MBAAm-co-AM) polymeric nanoparticles were successfully synthesized by a simple distillation–precipitation polymerization method. Due to the introduction of polymer, the SiO2/P(MBAAm-co-AM) nanoparticles show a favorable swelling performance in aqueous solution, and their particle sizes increase from 631 to 1258 nm as the swelling times increase from 24 to 120 h. The apparent viscosity of SiO2/P(MBAAm-co-AM) suspension increases with an increase of mass concentration and swelling time, whereas it decreases as the salinity and temperature increase. The SiO2/P(MBAAm-co-AM) suspension behaves like a non-Newtonian fluid at lower shear rates, yet like a Newtonian fluid at shear rates greater than 300 s−1. The EOR tests of the SiO2/P(MBAAm-co-AM) suspension in heterogeneous, low-permeability cores show that SiO2/P(MBAAm-co-AM) nanoparticles can effectively improve the sweep efficiency and recover more residual oils. A high permeability ratio can result in a high incremental oil recovery in parallel cores. With an increase of the permeability ratio of parallel cores from 1.40 to 15.49, the ratios of incremental oil recoveries (low permeability/high permeability) change from 7.69/4.61 to 23.61/8.46. This work demonstrates that this SiO2/P(MBAAm-co-AM) suspension is an excellent conformance control agent for EOR in heterogeneous, low-permeability reservoirs. The findings of this study can help to further the understanding of the mechanisms of EOR using SiO2/P(MBAAm-co-AM) suspension in heterogeneous, low-permeability reservoirs.
