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.

CNPC’s record-breaking 11,100-m exploration borehole in the Taklamakan Desert promises to unlock the science of producing oil and gas trapped in the world’s deepest reservoirs. -
A flurry of activity has resulted in several long-term contract extensions.

This paper presents a laboratory-based study that compares the three methods to measure static gel-strength development that are widely accepted in the industry.
-
The objective of this paper is to review selected completions to provide insights for adoption of multilateral technologies, including lessons learned, operational experience, and recommendations.

In 2022, the topics of the cementing and zonal isolation papers published were generally similar to those presented in previous years. A noticeable departure from previous years, however, was that many of the authors emphasized that their work would result in a reduction of greenhouse-gas emissions.
