In low-permeability sandstone reservoirs (LPSR), impermeable interlayers significantly challenge carbon capture, utilization, and storage (CCUS) enhance oil recovery (CO2-EOR) processes by creating complex, discontinuous flow units. This study aims to address these challenges through a comprehensive multi-faceted approach integrating geological microscopic analyses, including core analysis, reservoir petrography, field emission-scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), well-logging response utilizing three-dimensional (3D) modeling. The current investigation systematically characterizes interlayer types, petrophysical properties, thickness, connectivity, their spatial distribution in the unit. Numerical simulations were conducted assess sealing efficiency impact of various materials on CO2 flooding over 10-year period. Results indicate presence argillaceous interlayers, with optimal occurring barriers ≥ 4 m 1.5 thick. leakage occurs preferential pathways that emerge side-to-middle bottom-to-top direction interbeds, multidirectional showing greater at bottom compared upper side within barriers. Increased thickness constraints breakthrough but reduces vertical area production ratio homogeneous reservoirs. Augmented interbed mitigate time while constraining gravity override dispersion effects, enhancing horizontal displacement. These novel findings provide crucial insights for optimizing CCUS-EOR strategies LPSR, offering robust theoretical foundation future applications serving as key reference utilization challenging settings LPSR worldwide.

CO2 flooding can effectively enhance oil recovery in tight reservoirs. However, the mobilization characteristics and interlayer mass transfer mechanism of crude heterogeneous reservoirs with permeability ratio (PR) remain unclear. We simulated by fabricating artificial PR cores conducted experiments under different miscibility states. Moreover, nuclear magnetic resonance was employed to distinguish quantify high-permeability layers (HPLs) low-permeability (LPLs), revealing mechanisms. The results indicated that, compared those immiscible partially miscible flooding, yielded a higher overall recovery, continuing increase after breakthrough. This is primarily due significant efficiency LPL. At this stage, displacement becomes less effective, mechanisms, such as extraction diffusion between HPL LPL, become dominant drivers recovery. In state, oil–gas interfacial tension vanishes, thus enhancing effects. significantly promotes transfer, mobilizing contributions LPL during were quantified, that final contribution former 1.69 times greater than latter. verifies primary for breakthrough, emphasizing its critical role processes.

Optimizing oil recovery from mature reservoirs remains a key challenge in the petroleum industry. This study evaluates efficiency of CO2-WAG injection compared to continuous CO2 and water flooding using sector model X Oil Field. A compositional reservoir simulator was employed analyze under water-wet mixed-wet conditions, incorporating three-phase relative permeability wettability effects. The results show that yields highest recovery, with systems outperforming reservoirs. provides balanced approach, enhancing while enabling sequestration, but less effective than flooding. Water flooding, though least efficient terms demonstrates long-term production stability. gas–oil ratio (GOR) is notably higher CO2-WAG, indicating gas breakthrough challenges. These findings emphasize significant role enhanced (EOR) suggest most technique for maximizing heterogeneous contributes valuable insights optimizing strategies, improving hydrocarbon supporting sustainable management.

Marine heavy-oil reserves are enormous, and thermal recovery technology is one of the most effective ways to utilize them. However, steam as a high-energy external fluid will affect geological characteristics reservoir. In this paper, sensitivity reservoir was analyzed in terms high-temperature metamorphic clay minerals coupling damage particle migration heavy component deposition. Firstly, long-core cyclic stimulation experiments were conducted using supersaturated steam, saturated superheated quantify differences oil capabilities. Subsequently, variation components core under different temperatures by X-ray diffraction spectroscopy. Finally, influence heavy-component deposition on permeability clarified through displacement experiments. The results show that more than 12% higher throughput cycle effectively shortened. laboratory, only metamorphism due effective, mainly concentrated kaolinite monazite. Particle causes little reservoir, but formation coupled with can lead 30% becoming damaged.
