Summary: This study provides meso and microstructural observations of hydrocarbon movement along faults and fault zones and reveals the cyclic flow of hydrocarbons within tectonically active faults during seismic cycles. The results indicate the occurrence of pressurized hydrocarbon pulses during coseismic slip and the formation of fault permeability during the seismic phase. The findings contribute to the understanding of the hydraulic behavior of carbonate fault damage zones and have implications for hydrocarbon exploration and production.

Summary: Managed aquifer recharge is a method for water storage and recovery, but the migration of fines during water injection can significantly impact the permeability of the formation. Previous studies have focused on fines migration in sandstone and soil samples, with limited research on fines migration in carbonate rocks. Additionally, the effects of temperature and ion type on fines migration in carbonate rocks have not been investigated. This study conducted experiments using filtered-deaired distilled water and pure salts as injection fluids. The permeability of rock samples was measured through pressure difference, and effluent samples were collected for analysis. The results showed that fines migration was influenced by mineral dissolution and cation exchange, with different impacts observed for different brine solutions and temperatures.

Summary: Through innovative experimental set-up, a shear zone with cylindrical geometry was generated under in situ reservoir conditions, allowing for monitoring of permeability and fracture dilation evolution. The permeability and fracture dilation responses were found to vary between sandstone and granite, with reversible changes observed during pressure cycling.

Summary: Investigating the evolution of porosity and permeability in carbonate rocks during long-term infiltration is a challenging problem in rock engineering. The complex pore structures in carbonate rocks include various types of pores and fractures. In this study, a rock seepage coupled nuclear magnetic resonance (NMR) online analysis and imaging system platform was used to quantify the variation in pore volume at different scales. The results showed that the permeability-porosity evolution can be divided into three stages based on the experimental data and permeability measurements.

Summary: Natural gas stored in source rocks plays a significant role in meeting energy demand. Source rocks exhibit complex transport and storage processes due to their unique pore characteristics. Nanopores in source rocks offer large surface area for hydrocarbon storage. However, our understanding of the mechanisms behind hydrocarbon storage and transport is still limited. This study investigates the dominant diffusion mechanism in representative organic nanopores and finds that free molecular diffusion is the main mechanism. Additionally, the diffusivity coefficients deviate from theoretically calculated values, especially in post-mature cases. The deviation reduces with increasing pressure and pore size. The results provide valuable insights for better describing hydrocarbon transport in source rocks.

Summary: The brine-dependent recovery process, known as low salinity/smart water injection, is crucial for enhanced oil recovery in carbonate reservoirs. This study investigates the interactions between fluid and carbonate rocks, specifically focusing on the effects of mineral dissolution, precipitation, and multi-ion exchange. The research aims to determine the optimum water salinity for effective alteration in rock wettability towards water-wet conditions.

Summary: The depletion of reservoirs can lead to significant changes in the stress state of subsurface rocks and affect porosity and permeability, thereby impacting the productivity index (PI) of producing wells. A nonlinear analytical solution and perturbation technique are used to study the drawdown-dependent PI under steady-state flow regime. Results confirm the strong dependence of Well PI on drawdown magnitude.

Summary: This study investigates the well test interpretation and dynamic characteristics of low permeability porous carbonate rocks in the Middle East using the point source function and dynamic inversion method. The results show that the permeability around the well and well trajectory are the main factors affecting the water injection development effect of horizontal wells. This research provides important reference for adjusting injection-production parameters and optimizing scheme deployment.

Summary: Drying of geological formations by supercritical gas injection and the precipitation of salts may impact injectivity and productivity. Studies show controversial results on the effect on permeability, with experiments on dolomite formations showing a much larger effect on permeability compared to sandstone. Factors such as pore structure, capillary pressure, and water salinity control the impact of drying and salt precipitation on permeability.

Summary: The human somatosensory network relies on ionic currents to sense, transmit, and process tactile information. Researchers have discovered hydrogels that can transduce pressure into ionic currents, forming a piezoionic skin. These currents can directly modulate neurons and excite muscles, presenting a potential path towards bionic sensory interfaces.
