Summary: This study developed a three-dimensional hydro-mechanical coupling numerical model to investigate the mechanism of fracture-height propagation in laminated shale oil reservoirs. The results indicate that interface properties, stress conditions, and fracturing fluid viscosity have significant effects on fracture height propagation. A reverse-sequence fracturing technique is proposed to enhance the length and height of fractures in heterogeneous shale oil reservoirs.

Summary: In this study, a denoising approach combining VMD with energy value (EV) and VMD (VMD-EV-VMD) is proposed to separate the effective components and noise components after VMD and improve the denoising effect. Simulation experiments and pipeline leakage signal processing show that VMD-EV-VMD achieves a greater SNR and better denoising effect compared to other methods.

Summary: The encapsulation of xanthan gum by silica nanoparticles and lecithin has been investigated in this study. The stability of the formed capsules under various conditions is assessed, with silica-shelled capsules found to have greater stability than lecithin. The encapsulation of xanthan gum improves its thermal resistivity and the formed capsules show fair stability against high salinity conditions.

Summary: Adjusting injection and production parameters is crucial for studying the impact of reservoir heterogeneity on in-situ combustion and achieving stable ISC. The AIPISC method of asynchronous injection and production coupling is effective in achieving balanced sweep of ISC. Numerical simulation was used to define the reservoir and investigate the sweep characteristics, and AIPISC was successfully applied to heterogeneous reservoirs with improved results.

Summary: Coal tar, after processing, can be used as inexpensive blending components for the production of marine fuels. Linear optimization method is used to minimize costs and ensure the properties of the resulting products meet the required criteria. An innovative analytical method is used for fuel stability characterization. Polycyclic aromatic hydrocarbons (PAHs) and resin are identified as the main components affecting fuel oil stability, and hydrogenation effectively reduces their content, preventing fuel flocculation and deposition during aging in fuel tanks.

Summary: “Fracture extension simulation is an important tool for studying hydraulic fracture characteristics. By introducing non-localized treatment and implicit gradient calculation, a hydraulic-mechanical coupling model based on implicit gradient non-local damage was established, and a corresponding numerical simulation program was developed. The simulation results were validated by experimental data. It was found that introducing the implicit gradient nonlocal model can reduce the influence of mesh size on hydraulic fracture morphology and damage variables, effectively alleviating the localization effect.”

Summary: This study analyzed the movement of ball-sealers in steam using multiple analysis methods. The results showed that the movement of ball-sealers is influenced by various factors, including the density, diameter, quality, injection rate, and temperature of the ball-sealers. The temperature, quality, and injection rate of the steam play important roles in the effective plugging of ball-sealers. Additionally, the gas velocity and turbulent viscosity also affect the forces generated by the ball-sealers.
