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: 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: This study systematically evaluated the application potential of water-based drilling cuttings (WDC) as cementitious materials for building material admixtures. The physical and chemical properties of WDC were studied, and the environmental and human health risks of heavy metals in WDC were assessed. The results showed that WDC exhibited certain pozzolanic activity and could reduce harmful holes in the system. In addition, the study proposed resource utilization directions and environmental safety control measures for WDC.

Summary: Heavy metal pollution caused by oil well drilling operations is a significant environmental problem that needs precise determination of its source to manage and control it. The main source of pollution is found to be the drilling fluid additives or the elements in the well column formations. This research focuses on measuring the concentration of heavy metals and determining their exact origin.

Summary: This work investigates the characterization and leaching studies of pre-salt drill cuttings from offshore oil and gas exploration in ultradeep waters. The highest concentrations of Fe, Al, and Ba were found in the drill cuttings. Non-aqueous fluids contributed to the significant contents of Ba, Al, Fe, Cu, Pb, Mn, Si, and Zn, while aqueous fluids resulted in high concentrations of Ni and Cr. The samples showed different levels of total petroleum hydrocarbons (TPHs) content, and some cutting samples were contaminated with oil. Most samples were contaminated by polycyclic aromatic hydrocarbons (PAHs). Saline and aqueous leachates contained different metals in varying concentrations.

Summary: This study compares three systems for treating oil-based drilling cuttings (OBDCs) and analyzes the effects of oxidant initial concentration, Fe0 dosage, reaction time, and initial pH on the oil removal efficiency. The results show that Fe0/H2O2 and Fe0/PMS systems have better oil removal efficiency under acidic conditions, while the Fe0/PDS system is less affected by pH. Additionally, all three systems are effective in removing straight-chain alkanes, with the Fe0/H2O2 system demonstrating the highest degradation ability. Characterization of OBDCs before and after treatment reveals that Fe0 corrosion and the generation of Fe2+ promote the degradation of petroleum hydrocarbons in OBDCs.

Summary: The study found that ozone can enhance oxidation rates and remove hazardous substances containing PAHs in OPW; TNA exhibits strong photocatalytic capability; UV-LED can enhance the effectiveness of ozone and TNA, however, iodide may affect the oxidation of PAHs. The final recommendation is to treat OPW through sequential oxidation using ozone and the UV-LED/TNA/ozone system.

Summary: This article analyzes the relationship between the amount of cuttings drilled in a coal seam and stress level, finding a positive correlation between the amount of cuttings drilled and the degree of stress concentration in both the plastic fracture zone and elastic zone. The amount of drilling cuttings is closely related to roof weighting, and the irregular fluctuation of drilling cuttings serves as an approximate map of stress concentration distribution due to non-uniform cracks and defects in the coal seam.

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: Investigating the release of organic pollutants from bricks made from solid waste is essential. Based on experimental observation and model fitting, it was found that a joint diffusion-degradation mechanism controlled the emission of polycyclic aromatic hydrocarbons (PAHs) from the bricks. The diffusion-degradation model can better predict the long-term emission of PAHs in these bricks.

Summary: The study found that using water-based drilling cuttings (WDC) to make concrete can optimize mix ratios, improve mechanical properties, enhance workability and compressive strength. The silica and aluminum oxide in WDC react with calcium hydroxide to form new hydration products, contributing to the formation of concrete strength. Environmental leaching tests showed that adding recycled WDC to concrete is environmentally friendly.

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: The study indicates that carbon pricing policies mainly spread through learning from neighboring countries, and sometimes through imitation. Both carbon tax and cap-and-trade systems diffuse through the learning mechanism, with cap-and-trade also able to diffuse through coercion and normative pressure from EU member countries. Additionally, the adoption of carbon pricing policy by a country is driven by democratic political regimes and the level of coal production in the country.

Summary: Tourism is an important source of income for Small Island Developing States (SIDS), but climate change has had a significant impact on the industry. This review summarizes the literature on climate change and tourism in SIDS, highlighting the risks and impacts faced by the sector. While these countries have made efforts to mitigate emissions, CO2 emissions related to tourism transport remain a problem that developed nations need to address. Further research is needed to decarbonize the tourism industry and successfully adapt to climate change in SIDS.
