The environmental impact of traditional drilling mud treatments has become a growing concern in the oil and gas industry, prompting a shift towards more sustainable practices. Drilling muds, which are essential in wellbore operations, often rely on chemical additives to manage contaminants. However, conventional chemical treatments raise significant environmental issues, including toxicity, bioaccumulation, and long degradation periods. This study explores the development of eco-friendly treatment methods for contaminant removal in drilling mud systems, focusing on biodegradable and non-toxic additives as potential alternatives to harmful conventional chemicals. Our research involved the identification and laboratory testing of three primary categories of eco-friendly additives: biodegradable polymers, bio-surfactants, and water-based polymers. Each category was evaluated on its contaminant removal efficiency, cost-effectiveness, and overall impact on essential mud properties, such as density, viscosity, and pH stability. The results revealed that these eco-friendly additives demonstrated comparable, and in some cases superior, contaminant removal efficiencies relative to traditional treatments. For instance, water-based polymers achieved an average contaminant removal efficiency of 90%, while biodegradable polymers showed 85% removal efficiency. The cost analysis indicated potential savings of up to 30% per barrel when using eco-friendly additives, with water-based polymers being the most cost-effective. The study also examined the impact of these additives on drilling mud properties, finding that the eco-friendly options had minimal adverse effects on density, viscosity, and pH, thus preserving the functional integrity of the drilling mud system. Furthermore, these additives reduced the environmental risks associated with drilling mud disposal due to their biodegradability and low toxicity. The findings suggest that eco-friendly additives, particularly biodegradable polymers and water-based polymers, present a viable, sustainable alternative to traditional chemical treatments, offering both environmental and economic benefits. Future research should focus on scaling these solutions for field applications and further examining long-term environmental impacts. This study contributes to advancing sustainable practices within the oil and gas industry by providing evidence that eco-friendly treatment methods can meet the dual demands of environmental responsibility and operational efficiency.
