Strategic Consultancy for the Energy Sector

Our services

Valvestris supports executive & senior management in the oil & gas and renewables industries in making better decisions.

Project and Asset Reviews

Be it a Final Investment Decision on Project or a Decision to Acquire or Divest assets, Valvestris provides an independent and integrated review you can count on.

Business Planning

Assessing the robustness of your business plan can be difficult when you have worked on it yourself. Our team can quickly assess, both in the short and in the long term, the credibility of assumptions, the reliability of forecasts and the credibility of future scenarios.

Project Management

It is invaluable to have an independent view of your project execution plans based on decades of experience in running very large projects.


Our first-hand experience in setting and implementing strategy in diverse energy companies will let us assess the credibility and point out critical success factors.


We provide support, assurance and training in the areas of risk management, decision making and in managing interests in assets where you are a non-operator and hold a minority share.

Our Approach

To capture as much of our combined industry knowledge we have developed a suite of in-house maturity models called iVal®. This lets us benchmark every step of every phase of your project with peers or competitors.
