Drilling
The project with ExxonMobil used closed-loop drilling and digital well-construction technologies.
ExxonMobil's Jason Gahr uses the five stages of grief to explain how the upstream industry should respond to the rise of AI.
A multidimensional Wiener process approach predicts casing remaining useful life, enabling safe, cost-effective well life extension and repurposing for carbon dioxide injection, CCS, and geothermal applications.

The US onshore business is looking flat at the moment, though these sorts of predictions are prone to sudden shifts. -
The US-based drilling contractor is buying the drilling technology company just three weeks after announcing a merger with NexTier Oilfield Solutions.

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 authors discuss a modified ultrasonic-cement-analyzer (UCA) vessel that allows assessment of slurry sealing performance under representative downhole conditions while running otherwise standard UCA equipment.
-
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.
