This work introduces a novel predictive methodology combining historical metocean data with real-time riser analysis for shallow water dynamically positioned rig operations.
The deals, with a potential value exceeding $3.7 billion, are aimed at strengthening Saudi Aramco’s supply chains and expanding its use of industrial artificial intelligence.
ExxonMobil and its Area 4 partners have awarded $1.1 billion in pre-investment contracts for long-lead upstream equipment supporting Mozambique's Rovuma LNG project. The awards, led by OneSubsea, mark a key step toward FID as development advances on ExxonMobil's largest global investment.

Deepwater production has become more reliant on the integrity of subsea, umbilical, riser, and flowline (SURF) systems. A JIP explored cost-effective inspection and maintenance options. -
This paper presents the challenges and obstacles faced in the use of a new technology for the plugging and deoiling of sections of unpiggable flowlines before decommissioning.
-
Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.
-
Active slug-control methods have been developed in recent years. One such system is a relatively inexpensive solution developed by Shell that has proved to be very effective in stabilizing slugging in flowlines and risers.
-
Projects are being delayed or deferred due to low oil prices, which is affecting the market for subsea, umbilicals, risers, and flowlines (SURF).
-
More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
-
Use of surfactants and gas lift in combination to suppress severe slugging were tested. Surfactants were able to suppress severe slugging for most of the cases, and gas lift helped significantly.
-
Offshore drillers have been battered by the plunge in oil prices with falling day rates and a growing number of older rigs headed for demolition.
-
The roles of wellbore tubulars in delivering continued well integrity are diverse, critical, and congruent throughout the life of the well.
-
This paper describes efficient detection of well-control events, in both underbalanced and overbalanced conditions.
