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: The study highlights the importance of the Arctic as a potential resource for the industrial sector in the face of depleting conventional oil and gas reserves. The concept of sustainable development emphasizes the need for the circular economy in resource extraction to minimize environmental damage. This article compares two methods of drilling waste disposal and concludes that thermomechanical cleaning on site is the most effective in terms of both economy and the environment. It further evaluates the prospects and opportunities for drilling waste management in Russian offshore fields.

Summary: The study showed that OBDCA-sp/bauxite proppants had excellent performance at low mixture ratios, but increasing the ratio led to surface collapse of the proppants. X-ray diffraction results revealed a decrease in bauxite phase structure as the mixture ratio of OBDCA-sp to bauxite increased.

Summary: The oil exploration and production industry has played a significant role in the GDP growth of many countries, but environmental issues should not be underestimated. Shale gas, as a clean energy source, has gained considerable attention, and resources should be utilized efficiently to avoid waste. Focus should be on relevant policies and regulations, treatment methods, and environmental-friendly utilization.

Summary: This study investigates the chemical composition and pozzolanic activity of oil-based drilling cuttings residue (OBDCRs) and finds that high temperature calcination can activate the Si or Al components in OBDCRs, producing corresponding activity. Additionally, Ba2+ can promote the pozzolanic activity of OBDCRs, and the treated OBDCs' pozzolanic reactivity competes with that of conventional shale.

Summary: This study investigated the feasibility of recycling offshore water-based drilling cuttings (OWDC) from the Bohai oilfield in China as a raw material for manufacturing lightweight aggregates (LWA). The results showed that under the optimum preparation conditions, the OWDC-based LWA could meet the requirements of Chinese standard. The incorporation of OWDC lowered the aggregate melting points and promoted dense structure formation inside the aggregates. However, OWDC also had a negative effect on the compressive strength of the aggregates.

Summary: This study investigated the use of oil-based drill cuttings (OBDC) in asphalt pavement surface and studied the leaching of heavy metals from the pavement. The results showed that the maximum mixing proportion of OBDC of 4.8% met the technical requirements for highway asphalt pavements. Ba, Mn, Pb, and Zn were the characteristic heavy metals in OBDC, and their leaching behavior was studied. The leaching of Ba, Pb, and Zn was found to be of concern in the long term.

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: The study aimed to enhance knowledge on impact predictions near sensitive environments during drilling, emphasizing on the need to better characterize drilling fluid discharges to reduce uncertainty. High volume, concentration, and discharge rate water-based drilling mud discharges were identified as the most significant dispersal risk, but the generation of jet-like plumes limited longer-range movement.

Summary: Flocculation is an effective pretreatment technology for landfill leachate, but the effectiveness of the process is influenced by the operation sequence and the presence of colloidal instability. This study found that by separating the leachate and sludge first, and then adjusting the pH value to 9, the removal efficiency of organic matter from leachate can be significantly increased. This control strategy can provide theoretical and engineering references for the flocculation pretreatment of landfill leachate.

Summary: This study aimed to determine the eutrophication state of Lugu Lake and found that nitrogen and phosphorus pollution in the lake mainly came from internal sources. Dissolved oxygen and chemical oxygen demand were identified as the main environmental factors causing pollution. Sediment was found to be one of the main pollution sources, with nitrogen and phosphorus loads accounting for a significant proportion. Therefore, managing nitrogen and phosphorus contamination in Lugu Lake requires regulating the endogenous release of sediment and obstructing exogenous input from shrubland and woodland.
