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.

This paper describes a comprehensive approach to mitigate systemic failure in gas-lift valves in presalt wells. -
Friction reducers play multiple critical roles in fracturing. A challenge in selecting the best one for the job is the growing evidence that performance varies, but objective performance measurements are lacking.

This paper describes a study aiming to provide input for the well-completion-strategy design and operational parameters for a carbonate reservoir experiencing electrical-submersible-pump failures.

At peak, combined fields should produce more than 12,600 B/D of oil.

This paper describes the findings of a root-cause analysis of wellhead-penetrator failures in Canadian steam-assisted gravity-drainage operations and the mitigation measures taken.

A review of the properties of iron compounds and their impact in shale produced water treatment with an emphasis on their colloidal forms. A wide range of problems is associated with these compounds in produced water including emulsion stabilization, oil-coated solids, pad formation in separators, pipeline solids, and plugging of water disposal formations.

New case studies from this year's Offshore Europe were a reminder of how sustaining subsea reservoirs as they age often calls for determined and innovative engineers.
-
The obsession with better hydraulic fracturing has steadily pushed on shale production in year one, but the decline remains steep. Chemistry could help explain, and perhaps extend, the short productive life of these wells.

SponsoredWellbore deformation can occur at any stage in the life of a well. Whether a result of changes in temperature, pressure or tectonic forces, wellbore deformation may result in serious downhole issues such as restricted access for interventions or the loss of well integrity that may ultimately lead to premature well abandonment and significantly reduced economic perform…

SponsoredExtended reach wells provide access to otherwise inaccessible areas, improve production and reduce footprint. Advancements in completion technology allow producers to eliminate coiled tubing, perforation guns and milling out operations to lower project risks, costs, and environmental impact.
