Drilling
Operators aren’t rushing to drill, even as the closure of the Strait of Hormuz drives oil prices up.
This paper establishes that the use of a dual-gradient fluid column during the running of large casing in an extreme-reach deepwater well is an effective method to overcome drag and enable the casing to reach total depth.
This paper presents the first global application of autonomous drilling in deepwater and the journey to reach optimal drilling parameters, integrating proprietary tools from the project’s business partners.

This paper describes a machine-learning approach to accurately flag abnormal pressure losses and identify their root causes. -
Our drilling process is punctuated with discontinuous events that can disrupt the operational flow of the perfect well. Three papers have been selected to provide insights into some of these nonstationary processes that cause bit runs to fall short of perfection.
