Nanofluid's unique interface and small-scale effects offer significant potential in solving the low-universal problem of water flooding reservoir recovery. In the study, systematic micro- and macroscopic experiments, including microscopic visualization, core flooding, and nuclear magnetic resonance online flooding experiments, to reveal unique self-adaptive mobility control and superior displacement efficiency of amphiphilic graphene oxide (GOC)-based composite nanofluid. The results indicate that GOC nanosheets exert negative curvature at the oil-water interface, forming water-in-oil Pickering emulsion thermodynamically. These Pickering emulsions exhibit remarkable properties, with up to 90% internal phase volume and higher viscosity than oil across a broad water saturation, signifying GOC's self-adaptive mobility control in porous media. Furthermore, the Jiamin effect and in-situ thickening characteristics from the emulsion's micro-size compensate porous media heterogeneity, significantly improving the GOC nanofluid's macroscopic sweep efficiency. Moreover, a slight surfactant addition to the nanofluid further reduces oil-water interfacial tension to 10⁻² mN/m and regulates the rock surface's hydrophilic wettability, notably improving microscopic oil displacement efficiency. Therefore, the remaining oil and residual oil after brine flooding have been effectively utilized and efficiently displaced. The composite nanofluid with 0.3–0.7 pore volumes enhances oil recovery by 15.8%–37.7% after ultimate brine flooding. Moreover, carbon-based nanomaterials' synthesis is eco-friendly, and both carbon-based composite nanofluid preparation and the injection process are simple. These advantages show nanotechnology's excellent industrial application potential in improving oil recovery efficiency.</div></div>","PeriodicalId":37433,"journal":{"name":"Petroleum","volume":"11 2","pages":"Pages 211-225"},"PeriodicalIF":4.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, possible mechanism of the hydrolytic reaction of AB based on experimental results is proposed.

The study indicates findings in two aspects. First, the 1 500–1 800 m interval represents the critical transition zone between open fluid system in shallow–medium depths and closed fluid system in deep depths. The reservoirs above 1 500 m reflect intense water invasion, with discrete pressure gradient distribution, and the presence of methane mixed with varying degrees of secondary biogenic gas, and they generally exhibit high water saturation and adsorbed gas undersaturation. The reservoirs deeper than 1 800 m, with extremely low permeability, are self-sealed, and contains closed fluid systems formed jointly by the hydrodynamic lateral blocking and tight caprock confinement. Within these systems, surface runoff infiltration is weak, the degree of secondary fluid transformation is minimal, and the pressure gradient is relatively uniform. The adsorbed gas saturation exceeds 100% in most seams, and the free gas content primarily ranges from 1 m³/t to 8 m³/t (greater than 10 m³/t in some seams). Second, the gas accumulation in deep coals is primarily controlled by coal quality, reservoir-caprock assemblage, and structural position governed storage, wettability and sealing properties, under the constraints of the underground temperature and pressure conditions. High-rank, low-ash yield coals with limestone and mudstone caprocks show superior gas accumulation potential. Positive structural highs and wide and gentle negative structural lows are favorable sites for gas enrichment, while slope belts of fold limbs exhibit relatively lower gas content. This research enhances understanding of gas accumulation mechanisms in coal reservoirs and provides effective parameter reference for precise zone evaluation and innovation of adaptive stimulation technologies for deep resources.</div></div>","PeriodicalId":67426,"journal":{"name":"Petroleum Exploration and Development","volume":"52 2","pages":"Pages 435-444"},"PeriodicalIF":7.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143873787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fluid flow experiences a multi-scale transport process, starting from the matrix pore throats, extending to the natural fractures, and reaching the hydraulic fractures. Initially, tight and shale oil wells exhibit high production rates after hydraulic fracturing. However, this rapidly decreases due to insufficient energy in the reservoir, as well as formation damage to the reservoir, which impedes the multi-scale transport process. Consequently, effective systems for low-damage slickwater fracturing fluids and clean fracturing fluids to ensure the scale and effective development of tight and shale oil reservoirs after volume stimulation have been widely used. The pressure decay method and high back pressure displacement method have provided the valuable foundations for selecting fracturing fluids for tight and shale oil reservoirs. Nonetheless, challenges such as slow fluid transfer unpropped fracture closure, and water-phase trapping damage in tight and shale oil reservoirs need to be addressed urgently. Therefore, integrating fracture preservation, energy enhancement, and damage removal concepts will be essential for successful reservoir stimulation in tight and shale oil reservoirs. Additionally, exploring matching formation damage evaluation and fracturing fluid optimization technologies is crucial to achieving the efficient development of tight and shale oil reservoirs.

Physical self-assembly and anti-solvent methods were employed for constructing composite μAl particles. Characterization using SEM, XRD, XPS, FTIR, and μCT revealed a core-shell structure and homogeneous elemental distribution. Thermal analysis showed that PVDF coatings significantly increased the heat of combustion for aluminum particles, with maximum enhancement observed in μAl@PDA@PVDF (denoted as μAl@PF) at 6.20 kJ/g. Subsequently, 3D printed fuels with varying pure and composite μAl particle contents were prepared using 3D printing. Combustion tests indicated higher regression rates for Al@PF/Resin composites compared to pure resin, positively correlating with particle content. The fluorocarbon-alumina reaction during the combustion stage intensified Al particle combustion, reducing residue size. A comprehensive model based on experiments provides insights into the combustion process of PDA and PVDF-coated droplets.

Notably, the scope of application for the direct method in measuring EACN remains ambiguous. To address this, three different crude oil samples were analyzed, with their EACN values measured using the direct method.

Through the analysis of lithofacies and biomarkers, it is revealed that there are at least three kinds of isochronous source rocks (SRs) in the Cambrian Newfoundland Series in Tarim Basin, which were deposited in three sedimentary environments, i.e. sulfide slope, deep-water shelf and restricted bay.

In the produced oil, entire aryl-isoprenoid alkane biomarkers were detected, but triaromatic dinosterane was absent. This finding is well consistent with the geochemical characteristics of the Newfoundland sulfidized slope SRs represented by those in wells LT-1 and QT-1, suggesting that the Newfoundland SRs are the main source of the Cambrian petroleum discovered in Well XT-1. Cambrian crude oil of Well XT-1 also presents the predominance of C₂₉ steranes and is rich in long-chain tricyclic terpanes (up to C₃₉), which can be the indicators for effectively distinguishing lithofacies such as siliceous mudstone and carbonate rock.
