Production
After launching pre-salt production in Brazil, the ultradeepwater Tupi asset has become one of Petrobras’s most productive.
North Sea operators produced an additional 16 million BOE from 56 reinstated wells in 2025 as improved intervention efficiency lowered costs and helped restore shut-in assets to production, according to the NSTA.
This contributed article highlights the growing importance of fiber-optic sensing and its potential to advance thanks to emerging quantum technologies.

Present industry solutions to the challenge of well spacing involve expensive geomechanical Earth modeling or fracture-geometry monitoring that is time-consuming, data-intensive, and geography-specific. -
To further reduce backpressure on low-pressure gas wells and increase reserves in a mature gas field, a gas-ejector project was evaluated and proposed.

Primarily used in a few US states, waste-slurry-injection technology could help operators reduce cost, while also potentially reducing their carbon footprint. But the process may still present technical and environmental challenges.

About 16% of US offshore production in the Gulf of Mexico remains offline after Hurricane Laura caused mass evacuations more than a week ago.

The source of gummy, damaging polymer gunk that has flowed from Oklahoma oil wells is becoming clear, and one of the lessons learned is that shale plays require petroleum engineers to learn more about chemistry.
-
The featured papers and suggested further reading summarize the current SPE literature state of the art for H2S scavenger research and development and have been selected to give readers a broad indication from both academia and industry around the world.
-
This paper describes studies that confirm that enzyme-based, environmentally preferable chemistries can be used to break polymers and mitigate H2S in various systems.
-
Based on the early results from mass shut-ins of shale wells, it did not harm long-term production and it paid a short-term dividend with more oil flowing in the days after restarting.
