Onshore/Offshore Facilities
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.
SPE Offshore Europe 2027 has unveiled its conference theme, “(Em)Powering Europe: Securing Our Energy Future,” and opened the call for technical paper proposals for the Aberdeen event.
Flow measurement touches almost every phase of oil and gas operations. Yet the industry still struggles to distinguish between what is directly measured, what is inferred, and what is estimated through models, correlations, or assumptions. That distinction matters. A measurement does not need to be perfect to be useful, but it must be fit for purpose.

Offshore project execution enhancement ideas are highlighted for debottlenecking, gas-hydrate-induced pipeline vibration, and the design of subsea systems for efficient startup. -
The workflow aims to reduce the startup time of a subsea production system (SPS). A dynamic integrated model is used to adjust the scheduled SPS startup time. The model evaluates the dynamic simulation response of a large field startup by integrating a reservoir- and gathering-network model.
-
A computational fluid dynamics model is proposed to analyze the effect of hydrate flow in pipelines using multiphase-flow-modeling techniques. The results will identify the cause of pipeline failure, regions of maximum stress in the pipeline, and plastic deformation of the pipeline.

An operator in the western Gulf of Thailand retrofit two partial-processing water-management systems on mobile-offshore-production-unit platforms for bulk removal and treatment of produced water. Water debottlenecking increased oil production by 80% and reduced the infield transfer volume by 62%. Th

The long-term decommissioning of the historic Brent field has necessitated redevelopment of the younger Penguins field in the North Sea, where the UK hopes to see more revival projects in the coming years.
-
With $102 billion of decommissioning-related expenditure forecast to 2040 in Western Europe, opportunities are ripe for the supply chain to compete with innovative and cost-effective solutions for the E&P operators.
-
The shutting in of unprofitable offshore wells and the requirements for their plugging and abandonment is attracting more attention to what is being done with the associated subsea equipment. The benefits of leaving subsea systems in place vs. recovering them are being considered.
-
Weights used in the original construction of TransCanada’s Keystone Pipeline in South Dakota were identified as a preliminary cause of the failure that resulted in a 210,000-gal spill in November.
-
A new downhole-tool-based abandonment system was developed and deployed successfully on four wells for a major operator on a field in the North Sea.
-
The supply chain is now actively working to develop low-cost solutions and is gaining valuable experience through recent projects (as documented in many recent SPE papers). Owners need to engage the supply chain early with the relevant asset data for planning and execution of decommissioning.
