Abstract Image identification is a major means to achieve quantitative characterization of the microscopic oil displacement process. Traditional digital image processing techniques usually uses series pixel-based algorithms, which difficult real-time large-scale images. Deep learning methods have characteristics fast speed and high accuracy. This paper proposes four-channel segmentation method based on RGB color rock particle mask. First, micro model mask divided together with component form input data through technology. Pixel-level training set labels are then created traditional techniques. Through U-Net semantic network, pixel-level water recovery factor calculation polymer process were carried out. Combined pore distance transformation algorithm, lower limit utilization for different media was clarified. The results show that can accurate division areas. Compared conventional three-channel images, improved proposed in this has significantly accuracy due addition constraints mask, global be Up 99%. Combining some post-processing methods, found flooding increased mobilization degree small pores basis lowered from 25 μm 16 μm. In experiments, by 24.01%, finally achieving rapid network article strong adaptability flow channels Quantitative movement during provides new processing.

The application of surfactant flooding for enhanced oil recovery (EOR) promotes hydrocarbon through reduction oil-water interfacial tension and alteration oil-wet rock wettability into the water-wet state. Unfortunately, depletion in porous media, due to molecule adsorption retention, adversely affects recovery, thus increasing cost process. Chemical-based materials are normally used as inhibitors or sacrificial agents minimize adsorption, but they quite expensive not environmentally friendly. Plant-based (henna extracts) far more sustainable because obtained from natural sources. However, there is limited research on henna extracts reduce dynamic media improve such media. Thus, were introduced an eco-friendly low-cost agent minimizing static sodium dodecyl sulfate (SDS) onto quartz sand this study. Results showed that extent was inversely proportional extract concentration, surface a multilayer followed Freundlich isotherm model. Precisely, range 3.12-4.48 mg/g (for adsorption) 5.49-6.73 adsorption), whereas SDS 2.11 4.79 at conditions, respectively. In presence 8000 mg/L extract, significantly reduced by 64 82%, At same residual increased 9.2% over normal flooding. study suggests use during could result molecules sand, promoting sandstone formations.

Abstract Combustion of coal at thermal power plants generates enormous amounts fly ash (CFA). Proper disposal CFA is an important issue today because environmental problems are considered a burning worldwide. On the other hand, groundnut shells (GNS), regarded as agricultural waste in general, litter landfills everywhere and create soil degradation. Since both GNS contain abundant silica, this work focuses on extracting amorphous silica from these materials through total dissolution–precipitation process. The was extracted it used to prepare titanium oxide (TiO₂) hybrids. GNSS were GNS, CFAS CFA. methods based sol–gel. These hybrids further tested for performance their solar cells dissolving dyes. overall results obtained physical properties similar those conventional silica. More importantly, TiO₂/GNSS TiO₂/CFAS showed enhanced photocatalytic efficiency compared pure TiO₂. Therefore, evidence repurposing which have high potential use sustainable applications renewable energy remediation.

Significant amounts of hydrocarbon resources are left behind after primary and secondary recovery processes, necessitating the application enhanced oil (EOR) techniques for improving trapped from subsurface formations. In this respect, wettability rock is crucial in assessing sweep efficiency oil. The reservoirs inherently contaminated with organic acids, which renders them hydrophobic. Recent research has revealed significant impacts nanofluids, surfactants, methyl orange on altering organic-acid-contaminated formations into water-wet state. This suggests that toxic dye methylene blue (MB), presently disposed huge quantities contaminates waters, could be used EOR. However, mechanisms using MB solution attaining hydrophilic conditions not fully understood. Therefore, present work examines reversal Khewra sandstone samples (obtained outcrop Potwar Basin, Pakistan) under downhole temperature pressure conditions. prepared by aging 10-2 mol/L stearic acid subsequently treated various aqueous (10-100 mg/L) 1 week. Contact angle measurements then conducted physio-thermal (0.1-20 MPa, 25-50 °C, salinities 0.1-0.3 M). results indicate become hydrophobic presence increased pressure, temperature, salinity. changes oil-wet to preferentially solutions, thus highlighting favorable effects EOR formation. Moreover, most change observed sample was aged 100 mg/L MB. These suggest injecting deep underground may produce more residual hydrocarbons.

Fossil fuels are the primary global energy source, and their improved production will ensure a balance between increasing demand supply. Chemical-enhanced oil recovery has been well thought of as promising method for hydrocarbon production.

Moreover, attention become focused application hazardous pollutants such methyl orange methylene blue to enhance CO2/H2 containment security host by altering its wettability. Nevertheless, capacity modify trapped hydrocarbons in sandstone reservoirs is yet be explored. Thus, present study, used modifier from quartz rocks aged stearic acid solution (10-2 mol/L). First, organic-aged various concentrations (10-100 mg/L) one week at 60 °C. Then, contact angle measurements performed different temperatures (25 50 °C) under pressures (10-20 MPa) brine salinities (0-0.3 M). found turn hydrophobic organic acid/n-decane 20 MPa blue, hydrophobicity decrease, thus suggesting promoted treatment. Overall, results demonstrate most favourable condition reducing via treatment 100 mg/L blue. Hence, injection into deep underground potential produce more residual hydrocarbons.

The application of nanoparticles (NPs) in the oil and gas industry has received wide attention recent years because it is increasingly being considered a promising approach to recovering trapped conventional hydrocarbon reservoirs. Numerous studies have demonstrated that combining with surfactant can enhance performance by changing interfacial properties solution when comes contact crude rock surfaces. However, more information additional experimental data are required concerning titanium dioxide alkyl ethoxy carboxylic surfactants. In this study, we measure changes tension wettability due addition (0, 100, 250, 500 ppm) using spinning drop tensiometer angle measurements. oil–water (surfactant) system decreases approximately two orders magnitude an increasing concentration, exhibiting minimum value 5.85 × 10–5 mN/m. Similarly, on surface Berea sandstone dioxide, reaching 8.8°. These results demonstrate potential new maximize recovery significantly improve production.
