Offshore/subsea systems
The North Sea project, which is sending production to the nearby Ivar Aasen platform, came online 9 months ahead of schedule.
Equinor said it found between 14 million and 24 million BOE with its most recent exploration well in the Polynya Tubåen prospect.
BP sanctioned development of the Kaskida in 2024, with first oil from the high-pressure project expected in 2029.

Results of the experimental and numerical heat-transfer analysis conducted on a T-shaped acrylic-glass pipe, representing a production header in a subsea production system with a vertical deadleg. -
A real-time production-surveillance and -optimization system has been developed to integrate available surveillance data with the objective of driving routine production optimization.
-
A new tool enables variable bore rams and shear rams to be tested in one run, cutting rig time significantly.
-
Developing a well-specific subsea-capping contingency plan involves assessing the feasibility of deploying a capping stack from a floating vessel, determining the weight and stability, and performing dynamic-flow simulations of closing the capping stack outlets.
-
Subsea tieback of a new field to an existing offshore production facility is one option to minimize development costs.

Subsea processing is an evolving technology in ultradeepwater development and has the potential to unlock a significant amount of hydrocarbon resources. In this paper, the authors have reviewed the application of subsea systems in 12 deepwater fields and discussed the significance of each.
-
Successful rejuvenation of two declining fields was enabled through innovation in both engineering and procurement strategy.
-
The deepwater industry uses technology qualification (TQ) as a tool to determine which safety barriers are needed, and what level of testing is required. Even without failure data from the field, a method has been developed to quantify the integrity of various components.
-
Intervention and workover operations can significantly affect the structural integrity and fatigue life of subsea-wellhead systems. Methodologies for wellhead-fatigue analysis have improved, but have yet to account for thermal effects along the well. This study analyzes those thermal effects.
