From Data to Decision: The Role of 4.IR in Shaping the Future of Well Control and Integrity

Abstract

Drilling operations for oil and gas wells, constituting up to 40% of the total well cost, necessitate cutting-edge solutions for enhanced safety, efficiency, and well integrity. This research focuses on the integration of fourth industrial revolution (4.IR) technologies, specifically addressing well integrity within well control domains. The strategic application of machine learning, the internet of things, robotics, automation, and big data analytics aims to optimize operations, mitigate risks, and safeguard well integrity.

In the intricate landscape of drilling operations, the 4.IR technology becomes instrumental in ensuring well integrity. Rig sensors produce extensive, high-frequency data streams, and this research intricately examines how 4.IR technologies facilitate in-depth data analysis for safeguarding well integrity. The study delves into the technical advancements of 4.IR solutions, focusing on machine learning applications tailored for well integrity concerns, including early kick detection, pipe stuck prediction, wellbore stability, flux estimation, pore pressure prediction, and managed pressure drilling. Various machine learning techniques, data sources, features engineering, and target outputs achieved by developed models are explored.

The research highlights machine learning's outstanding impact on both the technical and economic aspects of well control and integrity. Case studies in the oil and gas industry demonstrate significant reductions in non-productive time (NPT), enhanced drilling performance, heightened safety, and lowered operational costs, with a central focus on preserving well integrity. The paper concludes by suggesting future avenues for machine learning applications, accentuating advanced data analysis, and addressing uncertainties in the well integrity domain. This collective insight positions machine learning as a transformative force in ensuring robust well control practices, aligning operational efficiency with economic viability while continually prioritizing the critical element of well integrity.

This research significantly contributes to the industry and academia by specifically addressing the role of 4.IR technologies in ensuring well integrity. Key features such as real-time monitoring, advisory systems, automation, digitalization, time and cost savings, and high accuracy for well integrity prediction and classification are explored. The integration of well integrity as a focal point within 4.IR applications in well control establishes a comprehensive framework for advancing safety and efficiency.
