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.

Linhua4-1 was China’s first tieback subsea development project. To develop this marginal oil field, a number of technical challenges were overcome through a series of new technologies, and their successful development and implementation. -
As oil and gas fields are depleted, artificial lift systems are often required to maintain delivery volumes and to maximize recovery.
-
Different artificial lift technologies have been used for decades to dewater coalbed methane (CBM) wells to reduce hydrostatic pressure and release the gas for production.
-
Onshore gas developments are often characterized by drilling, fracturing, and production of wells before low-pressure gas-gathering systems are in place. As well production declines, liquid-loading issues begin to appear. Use of a twin-screw pump to boost deliquefication was investigated.

The challenges for operators in the Eagle Ford have been enormous, which can push chemical management to the back burner. But there is a price to be paid down the road. Operators have recently become more mindful of implementing metric-driven chemical management programs.
-
This paper focuses on the applicability of subsea processing technology employing multiphase pumps to develop marginal fields commercially. Analytical methods were used to evaluate the pumps, and the results were validated through case studies in specific fields.
-
The growing amount of heavy crude processed worldwide has created additional separation challenges, leading some operators to turn to alternative technologies. In some cases, electrocoalescence has been an effective tool to separate oil from water.

This is the fifth article in a series covering water management in hydraulic fracturing in unconventional resources. The focus of this article is biological control. Additives to improve fracturing conditions can have negative effects on water treatment.
-
Sustainable growth in oil and gas production must stem from a combination of new discoveries and optimized recovery from maturing fields. Therefore, development of mature oil fields has been, and will increasingly be, an attractive subject.
-
The new channel-fracturing technique is capable of increasing fracture conductivity by up to two orders of magnitude.
