Abstract
This work presents a practical workflow for evaluating large-scale CO2 storage potential in regional aquifers, using the Troll aquifer in the North Sea as a case study. As CO2 storage activity increases, especially in shared geological formations, managing pressure and optimizing injection strategies become essential for safe and efficient operations.
The proposed approach combines pressure-limited capacity estimation, injectivity assessment, and dynamic screening to support early-stage site evaluation. It helps identify suitable well configurations and injection plans while ensuring that pressure limits are not exceeded. The workflow is designed to be computationally efficient and adaptable to complex geological settings.
By applying this methodology to a real-world aquifer model, the study demonstrates how integrated tools and modeling techniques can inform decision-making for future CO2 storage projects. The results highlight the importance of regional-scale planning and cooperation among storage operators to maximize capacity and minimize risks.
