Why we do it

We are convinced that subsurface operations are essential to shaping the energy landscape of today and tomorrow. With decades of operator expertise in the oil and gas industry, we can play a pivotal role in meeting the growing energy demand and advancing the energy transition.

That is why TSE is uniquely positioned to transfer our know-how to address future energy challenges – securing energy supply, reducing emissions, and supporting the energy transition.

As the partner of choice, we are committed to supporting the energy transition by serving the traditional oil and gas industry and players in the Geothermal, Carbon Capture and Storage, Hydrogen, and Gas Storage businesses.

With highly qualified experts and a proven international track record as operators in E&P upstream, storage, geothermal, and carbon management, we take pride in contributing our knowledge, entrepreneurial spirit, and expertise to deliver impactful solutions for businesses and society.

Our comprehensive technical and non-technical resources cover the entire upstream energy value chain and are strongly backed by decades of operational and professional experience.
