Eco-Friendly Drilling Fluids: Biodegradable Formulations and Performance Evaluation

Dear Colleagues,

The rapid growth of energy exploration has heightened global awareness of the environmental impact of drilling operations. Conventional drilling fluids, while effective, often contain components that can leave a negative impact on the environment. In response, the development of eco-friendly and biodegradable drilling fluids has emerged as a vital research frontier, offering to bridge sustainability, safety, and operational efficiency.
This Special Issue aims to showcase cutting-edge advances in biodegradable drilling fluid formulations, their rheological, filtration, and lubricity performance, and field-scale evaluations under diverse geological and operational conditions. Contributions are invited on topics including, but not limited to, the following areas:

• Novel natural or renewable raw materials for drilling fluid design;
• Green additives and bio-based polymers for performance enhancement;
• Laboratory and field evaluation methods for environmental impact and biodegradability;
• Comparative studies between conventional and eco-friendly fluids;
• Case studies demonstrating successful deployment in onshore and offshore drilling.

By bringing together innovative research and practical insights, we aimto produce a reference point for academia, industry, and policymakers working toward a cleaner, safer, and more sustainable drilling industry.
