State-of-the-art review on Automatic Vertical Drilling Tools: Addressing vibrational load challenges in oil and gas operations

In the evolving landscape of oil and gas extraction, Automatic Vertical Drilling Tools (AVDTs) play a critical role in enhancing drilling precision and efficiency. However, their performance is significantly influenced by dynamic vibrational loads, posing challenges to operational stability and longevity. This review provides a state-of-the-art overview of AVDTs under varying operational and vibrational conditions, with a focus on the computational and analytical approaches used to understand and mitigate these effects. Specifically, the paper examines the impacts of lateral, axial, and torsional vibrations on tool performance, safety, and maintenance requirements. By integrating theoretical models, simulation-based methods, and experimental data from real-world oilfield operations, this work offers a critical analysis of current advancements and persistent gaps in vibration analysis. Frameworks for addressing these gaps are proposed, emphasizing the need for advanced computational techniques, including simulation-driven design, smart control algorithms, and innovative material applications. Recommendations for future research highlight strategies to extend tool life, improve drilling accuracy, and minimize environmental impact. Key approaches include advanced vibration control, smart control algorithms, and novel material applications to enhance tool durability and performance. This review bridges theoretical insights with practical applications, leveraging computational methodologies to refine operational practices and advance AVDT technologies for harsh drilling environments, thereby contributing to the field of computational engineering in oil and gas operations.
