Guideline for Selection and Qualification of Sites and Projects for CO₂ Geological Storage (CO2QUALSTORE)

The recently published CO2QUALSTORE guideline serves as a reference for how to qualify, manage and approve CO2 geological storage sites and projects.

The guideline was developed by the CO2QUALSTORE joint industry project (JIP) led by DNV GL. The JIP included the following partners from a number of sectors; oil and gas companies (BP, BG Group, Petrobras, Shell and Statoil); energy companies (DONG Energy, Dea Group and Vattenfall); technical consultancy and service providers (Schlumberger and Arup); the IEA Greenhouse Gas R&D Programme; and two Norwegian public enterprises (Gassnova/Climit and Gassco). A workbook accompanying the CO2QUALSTORE Guideline gives practical examples of how to follow the risk-based guidance and its various steps. One of these examples is an advanced evidence based logic (ESL) approach developed with Quintessa's TESLA decision support software.
