Transforming Offshore Drilling: Automated Tubular Running Success in South Europe Deepwater Project

Abstract

This paper discusses the collaboration between Weatherford International and Eni to implement advanced tubular running services (TRS) automation technologies on a South Europe deepwater drilling project. This project represented a major shift for Eni, moving away from conventional tubular handling methods. By deploying state-of-the-art automation and rig integration technologies, the project eliminated manual operations in hazardous red zones, reduced on-site personnel by 33%, and significantly lowered the carbon footprint. The automated makeup system positioned itself onto tubulars, made up and analysed each connection per premium thread manufacturer criteria, then returned to standby—all with the press of a button. Handling equipment, including spiders and elevators, was fully integrated into the rig’s control system, and operated from the driller’s chair. Mobilizing these technologies required careful planning to address regulatory and logistical challenges, along with a comprehensive training program to ensure seamless adoption. The project scope included re-entry, completions, and drilling operations using the 22-150 and 7.6-30 automated makeup systems. Key outcomes included 1,685 successful connections with only two rejected joints, 460 operating hours with just 3.75 hours of non-productive time, and zero safety incidents. These results highlight the significant improvements in safety, efficiency, and environmental impact achieved through TRS automation, demonstrating its transformative potential for offshore drilling.
