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.

The two technology startups aim to bring scale to the visual side of oilfield automation with a new deal that will cover 90% of US energy assets. -
The performance of artificial-lift systems on horizontal wells is greatly influenced by both the volume of gas produced and the tendency for gas slugging.

Of the many steps in the journey toward maximizing run life, the first steps should be to identify the system requirements and communicate those to the vendor. This can be challenging, because operators and suppliers often speak different languages. Fortunately, international standards can help.
