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.

In an SPE webinar, “Foaming in Separators: Handling and Operation,” Wally Georgie, principal consultant at Maxoil Solutions, presented an overview of foam generation and how the design of processes and chemical management can exacerbate its detrimental effects in separators.

High-reliability gas lift flow-control devices (GLFCDs) enable gas lift for wells with the potential for H2S in the produced gas and where casing is not qualified for H2S service.

Artificial-lift reliability is strongly influenced by how well the equipment is selected, designed, and operated for its particular application. The required artificial-lift knowledge is more than simply entering data into a software program or taking one class on the subject.

Recently, Quicksilver Resources and Eni E&P, through its subsidiary Eni US Operating, began a common effort to optimize production and lift costs in the Alliance shale-gas field in the prolific Barnett shale play in Texas.

Fall velocities for various plungers have been measured under many different field and simulator conditions. A new theoretical plunger-fall-velocity model uses a specific pressure and temperature for calibration.

In the southern North Sea, many fields suffer from declining gas production because of reservoir-pressure depletion and associated liquid loading.

A successful field trial in which foam was used as a gas-injection conformance enhancer was implemented in the Cusiana field in Colombia.

Issues associated with mercury’s presence in hydrocarbon processing systems have become more apparent as deeper and hotter reservoirs (often with higher levels of mercury) were exploited, and with the low-temperature gas processing used for liquefied natural gas (LNG) and natural gas liquids.
