ONE-Dyas

What ONE-Dyas does

ONE-Dyas B.V. is a privately held Dutch upstream oil and gas exploration and production company formed in April 2019 through the merger of Oranje-Nassau Energie (ONE) and Dyas. Operating across the Netherlands, United Kingdom, and German sectors of the North Sea, it is described as the largest privately owned E&P operating company in the Netherlands, with reported 200 million boe of reserves and resources and an average 2024 production base of approximately 15,000 boe per day. Operated assets include the GEMS hub and the wind-powered N05-A platform, the unmanned M07-A platform, the F06-IJssel development tied back to Hanze, the late-life UK Sean fields, and the idle Q16-Maas onshore gas treatment plant; non-operated interests have been recently rationalized through the divestment of Catcher and Golden Eagle stakes to Serica Energy.

The company's core technology centers on a low-emission production architecture: the N05-A platform is fully electrified via a cable connection to the Riffgat offshore wind farm, eliminating combustion-based generation and achieving MiQ Grade A methane certification as the first North Sea natural gas project to do so. ONE-Dyas is also developing the Kompas carbon capture and storage project at the depleted Q16-FA field targeting first injection by 2030, and has signed an MOU with Symphony Wave Power on underwater wave-energy conversion. Revenue is generated through commodity sales of produced crude, natural gas, and NGLs from operated and non-operated interests, with BP serving as the contracted offtaker for N05-A certified gas marketed into Dutch and German utility and industrial demand (approximately 7% of Dutch and 2.5.5% of German gas supply at platform capacity).

Core offering

ONE-Dyas is an upstream exploration and production company that acquires, develops, and operates oil and gas assets in the Dutch, UK, and German North Sea. It produces and sells crude oil, natural gas, and natural gas liquids from operated platforms (GEMS/N05-A, M07-A, Sean, F06-IJssel, Q16-Maas) and previously held non-operated interests (Catcher, Golden Eagle). The company is also developing the Kompas carbon capture and storage (CCS) project for offshore CO2 injection by 2030.

Product overview

ONE-Dyas is an oil and gas exploration and production company operating across the UK, Dutch, and German North Sea. The company's portfolio consists of operated assets (GEMS/N05-A platform, F06-IJssel, M07-A, Sean fields, Q16-Maas) and non-operated interests (previously Catcher and Golden Eagle). ONE-Dyas positions itself as a responsible producer focused on near-zero emissions, with its flagship GEMS project featuring the N05-A platform powered entirely by offshore wind. The company is also developing the Kompas CO2 storage project for carbon capture and storage, representing its entry into emerging decarbonization services.

Products and services

• GEMS (Gateway to the Ems) ONE-Dyas' flagship operated development project in the Dutch and German North Sea, focused on the N05-A production platform and the future development of N04-A and N04-C fields. Designed as a hub for tie-back of future production from multiple gas discoveries (N05-A, N07-B, N04-A, N04-C).
• N05-A Platform Production and processing platform in the Dutch sector of the North Sea, fully powered by offshore wind energy from the German Riffgat wind farm. Achieved MiQ Grade A methane emissions certification and designed for near-zero operational emissions.
• F06-IJssel Field Gas and oil field located approximately 200 km north of Den Helder in the Dutch Central Graben, to be produced through the upcoming F06-A satellite platform connected to the existing F02-A Hanze platform.
• M07-A Platform Unmanned platform in the Dutch sector of the North Sea, designed for remote operation with solar panels and wind turbines for power generation. Produces gas from M07-A and M07-B fields, with gas transported via pipeline to the NAM-operated L09-FF platform.
• Sean Fields UK North Sea gas fields including Sean Papa (main facility with gas treatment) and Sean Romeo (wellhead platform), producing gas exported to the Shell-operated Bacton Terminal. The fields are in decommissioning preparation phase.
• Q16-Maas Onshore gas treatment plant at the Tweede Maasvlakte in the Port of Rotterdam, developed for the Q16-Maas field with unique high condensate content. The plant also processed hydrocarbons from the Maasmond field and currently sits idle.
• Kompas CO2 Storage
