Drilling
The company said that its AD-300, a 50-m-high automated island drilling rig that walks between wells, was delivered 3 months ahead of schedule.
A report commissioned by Havtil, the Norwegian Ocean Industry Authority, calls for better dialogue regarding pore-pressure uncertainty and higher-end drilling techniques like managed pressure drilling as methods to reduce the risk of well-control events.
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.

In this study, a method was developed to analyze the effects of drilling through transitions on bit-cutting structures and construct an ideal drilling strategy using a detailed drilling model. -
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.
