Abstract
Drilling wastewater generated during oil and gas operations presents a complex environmental challenge due to its highly variable composition, large volumes, and the presence of hazardous organic and inorganic contaminants. Conventional treatment approaches, although widely implemented, often fail to achieve consistent performance under dynamic operating conditions and increasingly stringent environmental regulations.
This review provides a comprehensive and forward-looking analysis of drilling wastewater management by integrating treatment technologies with emerging concepts of circular economy, data-driven intelligence, and uncertainty quantification. The characteristics and sources of drilling wastewater are examined to highlight their inherent variability and associated treatment challenges. Conventional, advanced, and hybrid treatment technologies are critically evaluated in terms of efficiency, limitations, and applicability for water reuse and resource recovery. Circular economy strategies, including water recycling, material recovery, and zero liquid discharge (ZLD), are also assessed from a sustainability perspective.
In addition, the role of machine learning in performance prediction, process optimization, and real-time monitoring is discussed, alongside uncertainty quantification approaches such as probabilistic modeling and Bayesian inference for risk-informed decision-making. From an industrial perspective, the integration of intelligent modeling and uncertainty-aware frameworks enables more reliable, adaptive, and efficient treatment systems.
Despite these advancements, challenges remain in data availability, model transferability, system integration, and economic feasibility. This review establishes a unified framework that bridges environmental engineering, data science, and sustainability, providing a pathway toward intelligent, circular, and resilient drilling wastewater treatment systems.

Abstract Persian

پساب حفاری تولیدشده در عملیات نفت و گاز، به دلیل ترکیب بسیار متغیر، حجم زیاد، و حضور آلاینده‌های خطرناک آلی و معدنی، یکی از چالش‌های پیچیده زیست‌محیطی محسوب می‌شود. روش‌های متداول تصفیه، علی‌رغم کاربرد گسترده، اغلب در دستیابی به عملکرد پایدار تحت شرایط عملیاتی دینامیک و الزامات سخت‌گیرانه زیست‌محیطی با محدودیت مواجه هستند.
این مطالعه مروری، تحلیلی جامع و آینده‌نگر از مدیریت پساب حفاری ارائه می‌دهد که در آن فناوری‌های تصفیه با مفاهیم نوظهور اقتصاد چرخشی، هوشمندسازی مبتنی بر داده، و کمّی‌سازی عدم‌قطعیت به‌صورت یکپارچه مورد بررسی قرار گرفته‌اند. در این راستا، ویژگی‌ها و منابع تولید پساب حفاری بررسی شده تا ماهیت متغیر آن و چالش‌های مرتبط با تصفیه مشخص گردد. همچنین، فناوری‌های متداول، پیشرفته و هیبریدی تصفیه از نظر کارایی، محدودیت‌ها، و قابلیت کاربرد در بازیافت آب و بازیابی منابع به‌صورت انتقادی ارزیابی شده‌اند. راهبردهای اقتصاد چرخشی از جمله بازچرخانی آب، بازیابی مواد، و سیستم‌های تخلیه صفر مایع نیز از منظر پایداری مورد تحلیل قرار گرفته‌اند.
علاوه بر این، نقش یادگیری ماشین در پیش‌بینی عملکرد، بهینه‌سازی فرآیند، و پایش لحظه‌ای بررسی شده و در کنار آن، روش‌های کمّی‌سازی عدم‌قطعیت مانند مدل‌سازی احتمالاتی برای پشتیبانی از تصمیم‌گیری مبتنی بر ریسک مورد بحث قرار گرفته‌اند. از دیدگاه صنعتی، یکپارچه‌سازی مدل‌های هوشمند و چارچوب‌های مبتنی بر عدم‌قطعیت می‌تواند به توسعه سیستم‌های تصفیه‌ای قابل‌اعتمادتر، تطبیق‌پذیرتر و کاراتر منجر شود.
با وجود این پیشرفت‌ها، چالش‌هایی همچون محدودیت داده‌ها، انتقال‌پذیری مدل‌ها، پیچیدگی یکپارچه‌سازی سیستم‌ها، و ملاحظات اقتصادی همچنان پابرجاست. این مطالعه با ارائه یک چارچوب یکپارچه که مهندسی محیط‌زیست، علوم داده و اصول پایداری را به هم پیوند می‌دهد، مسیر توسعه سیستم‌های تصفیه پساب حفاری هوشمند، چرخشی و مقاوم را ترسیم می‌کند.
