oa Dynamic-Common Risk Segment Mapping for Rapid CO2 Storage Site Screening and Assessment: A Case Study

This research introduces a novel Dynamic-Common Risk Segment (D-CRS) mapping methodology, a significant advancement for rapid CO2 storage site screening. Unlike static CRS mapping, D-CRS integrates dynamic plume behavior and pressure dissipation, enhancing storage security assessments. The method incorporates refined parameter estimations-injection rate, plume size, and time to hazards-with geomechanical constraints, aligning with EPA standards, to determine storage capacity.

Key innovations include a modified plume size prediction, accounting for gravity-driven injection rate variations, and a novel injection rate estimation considering near-wellbore heterogeneity. The D-CRS framework synthesizes these dynamics into color-coded maps, enabling rapid identification of promising sites within a targeted area of the complex Malay Basin, a real-world dataset with diverse hazards.

Leveraging authentic field data and sophisticated analytical techniques, this D-CRS methodology provides a realistic, efficient screening tool, empowering informed CCS deployment. This study further refines the understanding of pressure propagation and plume dynamics, offering a more refined approach to risk assessment. It establishes a robust foundation for future validation across diverse subsurface environments.
