About us



In December 2018 ONE and Dyas announced that agreement has been reached on the merger of their upstream energy businesses, in a combined entity called ONE-Dyas. This merger was completed in April 2019.


ONE-Dyas B.V. has a strong focus on the North Sea as its core area of operations. ONE-Dyas has the ambition to significantly expand its operated and non-operated business in this region over the next 3 to 5 years, and is looking to further build on its existing presence in Gabon. Through our excellent subsurface, operational and commercial capabilities, ONE-Dyas is uniquely positioned to capture growth opportunities and create both short and long-term value for all its stakeholders. Successful acquisitions of Sterling and Sean are excellent examples of ONE-Dyas’ ability to execute this strategy with significant success. ONE-Dyas is also actively looking at development and exploration opportunities to support our long-term growth aspiration, preferably ONE-Dyas operated assets, both within and outside of our existing portfolio. The Ruby discovery in the Dutch North Sea bordering Germany is evidence that there are still underexplored areas in the North Sea.
