Offshore/subsea systems
The $5.1 billion ultradeepwater project is Angola’s first integrated cross-block development and sits at the top of Azule’s Southern African portfolio.
Equinor and its partners’ investment in the Troll West Increased Gas Recovery North (TWIN) project aims to unlock around 11 Bcm of additional natural gas from the Troll field, with first production targeted as early as 2028.
In the fourth development phase, a planned tieback would connect resources from two North Sea discoveries to existing infrastructure at the Johan Sverdrup field, pending project sanction.

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.
-
The sharp downturn in the offshore oil business has sparked interest in using subsea pumps to add production. If those conversations turn into orders, it may convert this rarely used option into a commonly used tool for extending the life of offshore fields.
-
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.
