Summary In the pursuit of carbon neutrality and mitigation dioxide (CO2) emissions, researchers have been exploring various approaches to integrate capture, utilization, storage (CCUS) with enhanced oil recovery (EOR) techniques. CO2 injection has identified as a promising method reduce crude viscosity enhance its mobility within reservoir. However, high can lead gas fingering, causing channeling reducing sweep efficiency. While foam considered improve conformance during flooding, longevity is negatively affected by harsh reservoir conditions. Polymers, which could be used stabilizers, are limited pressures CO2-induced reduction, hindering their widespread industrial application. Nanofluids, colloidal suspensions nanoparticles in base fluid, emerged potential solution for petroleum industry applications, including wettability alteration, interfacial tension (IFT) efficiency improvement. Functionalized intensifying interactions oil, particularly through adsorption, promises more desirable CO2-EOR. Inspired drug delivery nanomedicine, this study proposes novel approach where loaded onto amine groups controlled slow release target zones, aiming mitigate maximize thereby enhancing CO2-EOR performance. Amine-functionalized were prepared 3-aminopropyltriethoxysilane (KH550), grafted polyethylenimine (PEI)-coated load structure, characteristics between nanofluid extensively examined. It was revealed that amine-functionalized exhibited decent adsorption capacity 3.3 mmol/g. Following absorption at 25°C nanofluid, ζ-potential CO2-saturated increased +38.21 mV, significantly stability. The considerably reduced IFT from 34.78 mN/m 7.82 80°C, 12 MPa. After 36 hours soaking contact angle on oil-wet sandstone surface decreased 121.39° 57.95°. Furthermore, it distinct phase rich heteroatoms appeared nanofluid-crude interface. Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry (MS) demonstrated microdispersed predominantly composed acidic heteroatom compounds, mainly form CxHyOz CxHyOzSn, highlighting amine-modified alter properties. These compounds played crucial role formation stabilization emulsions, well optimization oil-water Ultimately, coreflooding experiments, recovered an additional 15.33% following waterflooding.

Development of Amphiphilic Janus Molybdenum Disulfide Nanosheets and Their Application for Enhanced Oil Recovery

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(18), P. 17392 - 17403

Published: Sept. 3, 2024

Amphiphilic Janus molybdenum disulfide (MoS2) nanosheets have emerged as promising candidates for enhanced oil recovery (EOR) due to their low cost and exceptional interfacial properties. Nevertheless, research on the modification methods MoS2 remains scarce. In this article, we prepared amphiphilic (L-MoS2-C) by double-sided of using a starch template method. Specifically, l-glutamic acid (l-Glu) with hydrophilic carboxyl group was grafted onto one side nanosheets, while cetyltrimethylammonium bromide (CTAB) hydrophobic alkyl chain used other. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive analysis (EDS) characterizations confirmed functionalization CTAB l-Glu molecules over surfaces nanosheets. Benefiting from properties, L-MoS2-C presented excellent dispersion stability in brine spontaneously accumulate at oil–water interface, forming an elastic film. At 0–10,000 mg/L NaCl concentration, size distribution centered range 300–500 nm. ultralow concentration (0.005 wt %), can reduce tension approximately 60% stabilize emulsions emulsifier. Furthermore, possesses remarkable wettability alteration capability, altering contact angle quartz plate surface 104.3 30.3°, thereby converting capillary resistance into driving force. Micromodel flooding core experiments demonstrate that these superior properties enable nanofluid effectively mobilize remaining residual after water contributing additional 15.1% recovery. This work introduces novel method MoS2, offering low-cost, high-performance, highly nanoflooding agent tertiary sandstone reservoirs.
