Summary: The study found that the selected 'green' fracturing fluids are not less harmful than the 'conventional' ones, with no clear indication of lower chemical concentrations in the green fluids. The environmental fate of identified compounds in both green and conventional fluids does not seem to be distinct, and results from genotoxicity tests suggest that green fluids have similar potential as conventional fluids.

Summary: The study indicates that liquid flowback in low-permeability sandstone reservoirs is closely related to pore structure, boundary layer effect, and displacement pressure. The new method based on the capillary bundle model for quantitative prediction of liquid flowback accurately predicts the cumulative mass and liquid saturation changes in low-permeability sandstone reservoirs. The experiments conducted validate the effectiveness of the new quantitative prediction method.

Summary: The study found that certain hydraulic fracturing additives from FPW can be absorbed by wheat, affecting plant growth and yield. However, in real-world scenarios, uptake may be reduced due to natural degradation, treatment, and dilution of water. Despite this, due to existing data gaps, chemical-specific treatments and regulatory safeguards are still recommended.

Summary: This study investigated the influence of flowback time and flowback difference on the flowback behavior of shale fracturing fluid. Through permeability tests and analysis of water phase retention in shale samples, it was found that the retention of fracturing fluid in shale does not decrease with increasing flowback pressure difference. Increasing the flowback pressure difference can reduce the shale permeability damage rate, but the damage rate is still above 80%. The water phase mainly stays in the pore space with a diameter less than 100 nm.

Summary: This study proposes a new strategy to improve the anaerobic digestion of fracturing flowback fluid under high salinity stress by adding AQDS. Results show that the addition of AQDS effectively alleviates the inhibition of high salinity on the anaerobic digestion, and improves COD removal efficiency and cumulative methane yield. Additionally, AQDS can alleviate the damage to anaerobic microorganisms caused by high salinity and promote their metabolic activity.

Summary: Fracturing fluids are widely used in hydraulic fracturing of shale gas reservoirs, but the efficiency of fluid flowback is often less than 50%, which limits shale gas recovery. This study conducted microscopic experiments to simulate the flowback process of fracturing fluids in shale gas reservoirs and analyzed the mechanisms and factors affecting flowback/retention. The results showed that flowback efficiency is positively correlated with fluid concentration and gas driving pressure difference. The study also identified four mechanisms responsible for fluid retention and observed that flowback efficiency increases with higher capillary number. These findings contribute to the understanding of fracturing fluid flowback in shale gas reservoirs and provide guidance for reservoir development.

Summary: Nanomaterials, with their ability to reduce water molecular clusters and improve surface properties, can enhance the oil displacement effect in the development of low permeability and unconventional reservoirs. This study examined the impact of nano-SiO2 on the rheological properties, flowback, and subsequent oil displacement performance of fracturing fluid. The results showed that nano-SiO2 had little effect on the swelling and dispersion properties of the thickeners used in the fracturing fluid. However, it significantly influenced the rheological properties of the guar gum based fracturing fluid. Despite this, nano-SiO2 had little effect on the breaking time and viscosity of the fracturing fluid, but it improved the inhibiting clay swelling performance after gel breaking and had an excellent demulsification effect on emulsified crude oil. Additionally, the addition of nano-SiO2 increased the recovery efficiency of primary water flooding. Field tests in the Mahu tight oil reservoir of Xinjiang Oilfield demonstrated the success of nanoparticle flooding and fracturing integrated technology, with the cumulative oil production after fracturing operation being 20-50% higher compared to the comparison well.

Summary: The European Joint Programme HBM4EU aims to provide scientific evidence for chemical policy development and improve chemical management by coordinating and advancing human biomonitoring (HBM) in Europe. Arsenic (As) was prioritized under the HBM4EU initiative, which required addressing policy-relevant questions regarding exposure status. Internal exposure to inorganic arsenic (iAs), measured as Toxic Relevant Arsenic (TRA), varied among different sampling sites, with the main exposure determinants being the consumption of rice and seafood. The high concentration of DMA, a major constituent of TRA, in urine samples indicates potential health concerns for the general population of Europe.
