TotalEnergies Unites UK North Sea Portfolio With Repsol’s NEO NEXT in Major Upstream Merger
New entity NEO NEXT+ set to become the UK’s leading independent offshore producer with strong output growth projected for 2026
TotalEnergies has agreed to merge its United Kingdom North Sea oil and gas assets with NEO NEXT, the upstream venture backed by Repsol and HitecVision, forming a new combined company known as NEO NEXT+.
The move marks one of the most significant consolidations in the basin in recent years and places the merged entity at the forefront of UK offshore production.
The companies announced that TotalEnergies will hold a 47.5 percent stake in the new venture, while HitecVision will retain 28.875 percent and Repsol 23.625 percent, creating a structure designed to support long-term operational strength and financial stability.
The merger brings together an extensive portfolio of producing fields and infrastructure across the Northern and Central North Sea, including Alwyn, Dunbar, Elgin, Franklin and Culzean.
These assets provide the new operator with a robust reserve and production base that executives say will support output exceeding 250,000 barrels of oil equivalent per day in 2026. Leaders of the venture argue that the scale achieved through this transaction will deliver heightened efficiency, improved cash flow and a more resilient position in a region facing maturing fields and tightening fiscal conditions.
The North Sea has witnessed a wave of mergers since the implementation of the UK’s windfall tax in 2022, which encouraged companies to consolidate operations to manage costs and pursue economies of scale.
NEO NEXT+ is positioned to accelerate that trend, with the combined team signalling interest in further acquisitions and strategic partnerships as part of a basin-wide growth strategy.
As part of the transaction, TotalEnergies will retain up to 2.3 billion dollars in decommissioning liabilities linked to its historic asset base.
Analysts view this arrangement as a means of strengthening NEO NEXT+’s balance sheet while offering clearer long-term financial projections for the new entity.
The companies expect regulatory approval in the first half of 2026, after which NEO NEXT+ intends to operate as a leading consolidator and one of the most influential players shaping the next phase of the UK Continental Shelf’s development.
