Summary: This study examines the feasibility of producing clinker and cement from pyrolysis residues of oil-based drilling cuttings (ODPR). The study investigates the effects of calcination temperature, ODPR content, and ODPR/GGBS ratio on cement performance. Additionally, it evaluates the environmental performance of clinker and cement products. The findings demonstrate that the addition of ODPR reduces calcination temperature and enhances the burnability of the raw cement meal. The physical-mechanical and chemical compositions of the cement products meet the Chinese standard for Common Portland Cement, and the environmental performance meets the corresponding Chinese standards. This study provides an effective solution for recycling ODPR in the oil and gas industry.

Summary: Results from laboratory experiments on cuttings transport performance using different oil-based drilling fluids with varying viscosities designed for highly deviated wells revealed that the hole cleaning abilities of the fluids significantly vary with well angle, drill string rotation, and flowrate. Low viscous fluids are more efficient at higher flowrates and low drill string rotation, while more viscous fluids are efficient with high drill string rotation rates, which is consistent with field experience. The findings demonstrate the importance of hydraulic design in achieving optimal cuttings transport efficiency in drilling operations.

Summary: The performance and intrinsic mechanism of vivianite in peroxymonosulfate (PMS) activation and pollutant degradation were comprehensively investigated. Vivianite efficiently activated PMS to degrade pharmaceutical pollutants, with higher reaction rate constant compared to magnetite and siderite. Various processes including SO4 center dot-, (OH)-O-center dot, Fe(IV), and electron transfer were involved in the vivianite-PMS system, with SO4 center dot- identified as the major contributor to pollutant degradation. Mechanistic explorations revealed that vivianite could bind PMS and rapidly activate it due to its strong electron-donating ability. Furthermore, vivianite could be efficiently regenerated through chemical or biological reduction. This study highlights an alternative application of vivianite beyond phosphorus recovery.

Summary: This study investigated the pollution status of petroleum hydrocarbons and the leaching toxicity of heavy metals in pyrolysis residues from oil-based drilling cuttings. The results showed that the pyrolysis residues had high content of petroleum hydrocarbons, with zinc and lead being the most polluted heavy metals. The ecological risk assessment indicated low potential ecological risk from multiple heavy metals in the residues. Furthermore, there was no non-carcinogenic risk to adults from the residues, but there was a noticeable non-carcinogenic risk to children.

Summary: Establishing simple and effective methods to tackle water pollution problems is of great significance. In this study, Co-loaded hollow carbon sphere (Co-HCS-1) was synthesized as a PMS activation mediator. The hollow structure of Co-HCS-1 increased the specific surface areas and active sites, facilitating the direct electron-transfer oxidation between PMS and pollutants. The embedding of Cobased catalyst in the shell of hollow carbon sphere enhanced the spatial confinement effect, accelerating the charge transfer between PMS and Co-HCS-1 and promoting the removal of organic pollutants in simulated wastewater.

Summary: The application of metal-organic frameworks (MOFs) in advanced oxidation processes (AOPs) for pollutant removal has attracted significant attention. In this study, a highly efficient and stable catalyst derived from sulfurized Co-doped MOF (SCo-MOF) was fabricated for peroxymonosulfate (PMS) activation. The catalyst showed improved catalytic performance due to reduced charge transfer resistance and the predominant presence of Co(II) resulting from sulfurization and Co doping. Additionally, the study investigated the effects of PMS concentration, catalytic dose, and coexisting ions on pollutant degradation.

Summary: The disposal effect of thermal desorption of oil-based cuttings is predicted by analyzing the material temperature rise, heat transfer, and liquid evaporation in the processing. This study establishes the governing equations for the simulation calculation of thermal desorption processing and demonstrates the correlation model between the mass change of wet components and the heat required. Changes in the material temperature and mass content of wet components in the process are calculated using the finite-volume method.

Summary: This study focuses on the distribution and leaching behavior of polycyclic aromatic hydrocarbons (PAHs) in oil-based residues of shale gas drilling cuttings. The results show that the concentration of 4-ring PAHs is the highest, and the concentration of PAHs decreases with increasing particle size of the residues. The leachate from the tested residues shows different PAH concentrations during the leaching process, with each leached PAH accounting for 1.50-3.20% of the total PAHs. The leaching characteristics of PAHs are best described by the first-order diffusion model (FRDM), with the leaching rate initially controlled by surface wash-off and then by diffusion.

Summary: A novel biofilter-constructed wetland coupling system has been successfully implemented in over 160 domestic sewage treatment projects in different cities of Zhejiang province, China. The long-term evaluation of a selected project revealed a stable and good water quality, meeting the regulatory standards for discharge of water pollutants. Big data analysis showed a strong polynomial relationship between effluent TP and NH4+-N concentrations, as well as a positive linear correlation between effluent CODCr and NH4+-N concentrations. pH had a stronger correlation with C/N, while effluent NH4+-N and TP concentrations had weaker correlations with pH. Additionally, a comparison study demonstrated that the enhanced system achieved higher removal efficiencies for CODCr, NH4+-N, and TP compared to the original system.

Summary: Outbreaks of periphytic algae, including filamentous algae, are common in early stages of submerged macrophyte restoration. In this study, the dynamic changes and characteristics of periphytic algae on Vallisneria natans and artificial V. natans were compared. The results showed that V. natans had more periphytic algae species and lower cell density and chlorophyll a content compared to the artificial substrate. The findings contribute to the understanding of substrate specificity on periphytic algae communities and have implications for the restoration of submerged plants in eutrophic lakes.

Summary: This study examines the preparation of low-density and high-performance proppants using water-based drill cuttings (WBDC) and bauxite as raw materials. Various factors such as sintering temperature, sintering period, material ratios, doping with iron oxide, and acid modification of WBDC are investigated for their effects on proppant properties. The proppant's performance is evaluated according to national standards, and its morphology and crystal phase structure are analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. Proppant Z-23 satisfies the standards completely, offering a new perspective for the resource utilization of WBDC and the preparation of low-density proppants.
