Geological CO2 storage site characterization and performance prediction

Overview

This solution delivers comprehensive geological CO2 storage site characterization and performance prediction services. It addresses the critical challenge of assessing how much CO2 can be stored at a potential site and demonstrating that the site meets required storage performance criteria. The approach integrates geological data collection, stratigraphic analysis, and performance simulation to support safe and efficient carbon storage projects.

The service is designed for operators, developers, and project sponsors planning CO2 storage in deep saline formations, depleted oil and gas fields, or coal seams. By combining site-specific geological data with predictive modeling, it enables informed decision-making on storage capacity, containment security, and operational optimization.

Technical specifications

Core capabilities:

• Storage capacity assessment across multiple geological media, including deep saline formations, depleted hydrocarbon reservoirs, and coal seams
• Stratigraphic analysis of caprocks and seals to evaluate site integrity and identify permeability barriers that impede CO2 migration
• Geological modeling that integrates site-specific data to simulate and predict storage performance
• Verification of CO2 quantities stored through various trapping mechanisms
• Optimization of storage project efficiency, including utilization of storage volume, injection pressures, and placement of new injection wells
• Monitoring-based demonstration that CO2 remains contained within intended storage formations
• Early detection of leakage or seepage with mitigation guidance

Key considerations:

• Storage site requirements vary significantly depending on the trapping mechanism and geological medium
• Caprock and seal integrity is a primary determinant of long-term containment
• Much of the required data is site-specific and must be integrated into geological models for accurate prediction

Technology readiness level

The methodology reflects the principal industry approach for assuring that CO2 remains stored and that performance predictions can be verified. Site characterization requires collection of a wide variety of geological data, which is integrated into geological models used to simulate and predict site performance. The approach is established and applied as the standard method for storage performance assurance, with ongoing validation through monitoring techniques and leakage detection protocols.
