The awards build on Tenaris’ role in earlier phases of the ultradeepwater Black Sea project.
Engineering, procurement, construction, and installation awards made at the end of 2025 are expanding Saipem’s role in Turkey’s two largest offshore gas fields, plus Saudi Arabia’s Berri, Abu Safah, and Marjan oil fields and Qatar’s North Field gas giant in the Persian Gulf.
The Gorgon Phase 3 project aims to counter declining reservoir pressure to sustain gas supplies to Western Australia’s domestic market and support LNG exports to Asia.

Severe slugging is characterized by large pressure fluctuations at the base of the riser and is accompanied by fluctuations in fluid delivery from the top of the riser. This instability has negative effects on downstream equipment. -
This paper provides an overview of an engineering-design methodology that can be followed for tubular-equipment sizing and selection for use in complex wells.
-
This paper will demonstrate the benefit of liner-drilling technology used to drill and cement an operator’s 9⅝- and 7-in. liners in place.
-
Results from a well recently drilled into an underpressured reservoir in southern Mexico.
-
The NORSOK standard focuses on the establishment of well barriers and well-barrier elements, and how these are accepted and monitored to prevent loss of well integrity that ultimately could lead to a loss in wellbore-fluid containment.
-
This paper reviews the mechanisms of initiation and the prevention of top-of-the-line corrosion (TLC). Recent research and developments are highlighted and validated to arrive at best practices for control of this significant corrosion manifestation.
-
The Papa-Terra field in the Campos basin in Brazil is identified as having an oil interval of 14.6°API in turbidite sandstones.
-
This paper presents the results of a performance-improvement effort in extended-reach drilling (ERD) in three campaigns in the Huizhou HZ 25-4 oil field in the South China Sea.
-
This paper presents results from full-scale testing of a flexible riser equipped with embedded sensors for distributed-temperature sensing (DTS).
-
Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
