Summary: We introduce a new experimental approach to investigate the injectivity impairment caused by reinjection of produced water in an oilfield. The experimental setup allows us to determine the kinetics of cake formation and damage propagation in the porous medium. The results show that the damage strongly decreases the global permeability of the porous medium and is influenced by temperature through the variation of viscosity.

Summary: In geothermal projects, reinjection of produced water is a key process for disposing wastewater, supplying heat exchange media, and maintaining reservoir pressure. This review comprehensively discusses the factors influencing injectivity during reinjection, including clogging mechanisms leading to injectivity decline and mechanisms contributing to injectivity enhancement. Strategies to avoid and recover from injectivity reduction are also introduced. Mixed-mechanism processes play a key role during reinjection. Future research directions to enhance understanding of injectivity-related issues are provided.

Summary: This study employs a coupled lattice Boltzmann method and discrete element method (LBM-DEM) to investigate the particle migration in the produced water reinjection process. Through simulations, three clogging scenarios were identified and it was found that mix clogging should be avoided. The results also suggest that the size range of injected particles should be as small as possible and the ratio of particle diameter of porous media to median particle diameter of injected particles (D/d(50)) should be larger than a critical value.

Summary: Production water reinjection (PWRI) is a mandatory practice for waste disposal, but it is associated with severe injectivity decline. This paper proposes a data-driven strategy based on machine learning and fuzzy logic to determine injection rates for wells, providing a potential solution to maintaining injectivity levels while maximizing injection rates.

Summary: This paper investigates the clogging mechanisms caused by clay particles in geothermal sandstone reservoirs. The results suggest that clogging occurs in two stages: surface deposition and pore bridging. SEM images provide further evidence of pore-blocking clay ribbons.

Summary: Coalbed methane development is accompanied by the emission of associated water, which, if not properly treated, poses a great threat to the environment and human health. This study explores the feasibility of reinjecting the produced water into the original coalbed and analyzes the effect of different water injection parameters on gas production using reservoir numerical simulation.

Summary: This study investigated the coagulation-based treatment processes for surfactant-polymer (SP) flooding produced water. The results showed that the hybrid ozonation-coagulation (HOC) process performed better than pre-ozonation coagulation (POC) process in terms of removal efficiency and ozone dosage. Additionally, the HOC process effectively inhibited water quality deterioration.

Summary: This study investigates the degradation of crude oil in oilfield produced water (OPW) by immobilized bacteria and the enhancement of oil recovery by reinjecting treated OPW. The results show that the immobilized bacteria effectively remove crude oil from OPW and improve the oil production efficiency after reinjection.

Summary: During offshore production, produced water is typically discharged into the sea, but re-injection is considered more environmentally friendly and cost-efficient with challenges in injectivity. Knowledge gaps exist in research on permeability reduction due to the flow of diluted oil-in-water emulsions.

Summary: Identifying the fate of contaminants, such as barium, during gas field produced water reinjection is important for evaluating environmental risks and improving sustainability. In this study, a series of water-rock interaction experiments were conducted to investigate the effects of various factors on the sorption of barium in sandstone. The results showed that the sorption of barium strongly depends on the brine/rock ratio.

Summary: In this paper, the flow structure beneath solitary waves with constant vorticity on an inviscid conducting fluid bounded above by a dielectric gas under normal electric fields was numerically investigated. It was found that the location of stagnation points does not change significantly with a variation of the electric field for elevation solitary waves, while the electric field acts as a catalyzer that makes possible the appearance of stagnation points for depression solitary waves.

Summary: Aerosols, suspended liquid or solid particles in the atmosphere, have significant impacts on air quality and the Earth's radiative balance. Dry deposition is a key process for removing aerosols, influenced by particle size and turbulence. However, there are gaps in research, such as deposition over the cryosphere and ocean surfaces.

Summary: This study presents the water retention characteristics of expanded perlite produced from two different raw materials in Turkey and China. The results show that the particle size distribution and water retention of the perlite samples have similarities but also differences between the two sources. It is suggested that the water retention of different particle sizes of perlite can be determined by the actual pore volume in the particles, excluding occluded pore volume.

Summary: This study investigates the accumulation features of aerosol particles on five typical urban plants and the relationships between leaf traits and particle retention. The results show that leaf traits, such as stomatal area, stomatal density, specific leaf area, and epicuticular wax content, are closely related to the retention of aerosol particles. This research contributes to understanding the interactions between leaf traits and particle retention, and it is significant for selecting plants that can alleviate urban air pollution.
