CO₂Wells: guideline for the risk management of existing wells at CO₂ geological storage sites

Topic(s): CO₂ storage, Engineering and project delivery

Carbon Capture and Storage (CCS) technology offers the potential to reduce greenhouse gas emissions from industrial sources by permanently storing (sequestering) carbon dioxide in deep geological formations. This Det Norske Veritas guideline describes a work process for managing the risks and opportunities associated with existing wells at CO₂ storage sites.

This publication is the final deliverable from the CO₂WELLS Joint Industry Project (JIP). The JIP addressed industry and regulatory concerns about the potential for CO₂ leakage along abandoned wells, and additionally existing wells and well conversions.

The sponsors of the CO₂WELLS JIP were: DNV, Shell Canada, Petrobras, Vattenfall, E.On New Build & Technology Ltd. and E.ON Gas Storage GmbH, RWE Dea AG, UK Health & Safety Executive, National Grid, Global CCS Institute, Gassnova SF and Gassco AS.
