Drilling
The SPE Drilling Systems Automation Technical Section has a new name—and a bigger mission. Discover how DSATS is evolving beyond automation to drive smarter, more connected, and more human-centered drilling systems for the future.
This paper presents the development of a digital tool for automatically analyzing the readiness of a borehole to accept casing. The tool integrates data-driven and physics-based models to indicate locations of risk along the wellbore.
Although the global total drilling rig supply is tightening as contractors sell off modern units for nondrilling purposes, day rates are expected to remain flat or dip in the near term, according to an analysis by Esgian.
