Summer School

The Summer School was divided into two weeks:

Week 1 (16-20 August) -  CO₂ storage in subsurface
Week 2 (23-27 August) - Produced water management

The goal of the school was to provide the participants with a deep understanding on selected topics in CO₂ storage and Produced Water Management and their associated challenges and opportunities.
