To overcome this obstacle, the incorporation of tracer injection along with the fracturing fluids and flowback analysis provides fundamental knowledge for reservoir characterization. Herein, a magnetic Pickering nanoemulsion is introduced as a potential tracer for hydraulic...

... This means that for injecting 5000 m 3 /d gas in an IGL well flowing in 55/5 minute cycle time, the average instantaneous rate of gas injection is 60,000 m 3 /day, which is too high. Multiple intermittent gas lift wells are typically connected to a centralized high-pressure gas source...

... is a flow assurance challenge for offshore oil and gas operations with subsea pipelines, wells, and tiebacks. In Water-Alternating-Gas (WAG) operations, hydrates can form within the injection wells when switching from water-to-gas and vice versa. This study investigates hydrate formation in a WAG injection...

Model bonding: Use 800-1500 mesh number sandpaper to gradually polish and process the etched glass chip to ensure the surface is flat, smooth, and clean. After that, silica...

..., and used a modified form of Stone’s expressions ( Stone 1970 , 1973 ) to generate three-phase relative permeabilities for oil, water and gas systems. The author adjusted relative permeability endpoints with temperature and found that in order to fit injection data and field water-oil ratios, irreducible...

The main novelty of this research lies in the experimental data that demonstrated enhanced bitumen drainage by DME-SAGD in comparison to SAGD. The experiment was conducted in a cylindrical pressure vessel with a diameter...

These authors also reported elevated concentrations of the intermediate components (C 11 -C 25 ) in the produced oil (lighter crude, injection quantity: 6.95 wt.%, soaking time: 24 h, operation temperature: 108 °C), similar to the observations of this study. According to Peng et al...

... Abstract Injection of CO 2 into subsurface coal seams is a viable technology for reducing the carbon footprint. The primary storage mechanism in coal, gas adsorption, is distinctively different from other subsurface reservoirs, providing secure and long-term storage for carbon; however, CO 2...

Third, the storage systems with multi-sealing layers were modeled to examine the effective drainage area, injectivity, and storage capacity under different drilling and injection schemes. Finally, the potential issues of carbon storage in depleted shallow gas fields were addressed...
