There is a better way to do this.

Agerion was founded in 2026 by Vanrisch McLean, a senior-level geoscientist who spent over 20 years working at the sharp end of subsurface characterisation before choosing independence. A deliberate decision to do it his way, to do it faster, and to do it without conflicting purpose.

Vanrisch began his career in oil and gas exploration and production, evaluating and drilling numerous exploration and development wells across the UK and Norwegian continental shelves and Central Europe. Prospect generation, seismic interpretation and inversion, well planning, and drill-or-drop decisions where the consequences of getting the geoscience wrong were measured in the tens of millions. That foundation in classical petroleum geoscience, the rigour of petroleum systems thinking, and the discipline of working with incomplete data under pressure, has shaped everything that followed.

A strategic move into offshore wind brought a new realisation. The industry was building its site characterisation practice largely from the ground up, often without drawing on the techniques available from adjacent industries. From his first forays in offshore wind, Vanrisch questioned the way it was done. He questioned the norm. He saw, consistently, that there was a smoother path available if you were willing to look outside of the norm for the tools to create it. Over the following eight years, working for a major developer and then building and leading one of the largest geoscience departments in the industry at a leading engineering consultancy, he proved it. Ground models delivered across over 10 GW of fixed and floating offshore wind projects spanning the UK, Southern Europe, South Korea, Japan, Taiwan, Australia, and the Americas. Quantitative interpretation adopted. Specialist partnerships established. He has contributed directly to the definition of emerging international standards for floating wind site characterisation. The thesis became reality.

Agerion exists because the value Vanrisch delivers requires independence. Senior geoscience judgment, applied directly to the decisions that matter, without the overhead, delegation, or conflicting priorities of a larger organisation. No project teams. No hand-offs. The person who leads the engagement is the person who does the work.

Every engagement is personal. There is no dilution of expertise between the person you briefed and the person who delivers. If the problem sits at the intersection of geoscience and a decision that matters commercially, that is where Agerion operates.

For as long as he can remember, Vanrisch has had a passion for making maps and a deep interest in analysing and understanding them. He turned that into a career. Agerion is where it leads, and where it matters most.
