4th Meeting of the Wellbore Integrity Network Meeting

1 August 2008
Event Proceedings
Storage

The broad aims of the network remain unchanged, and they are: To provide confidence to all stakeholders that the mechanisms involved with maintaining wellbores are understood. That the safety of storage, specifically in relation to wellbores, can be ensured because the risks can be identified and minimised. That wellbores can be monitored for early signs of leakage and remediated as necessary. The meeting also had some specific aims identified in the conclusions from the 3rd meeting, and these included: Investigating the contrast between field and lab results. Updating the advances in technologies and understanding, as was seen between the 2nd and 3rd meetings. Continued investigation of the advancements made in the modelling of wellbores and the reactions between CO2 and wellbore materials.

An Assessment of the Potential for CO2 Storage in the Indian Subcontinent

1 May 2008
Storage

This project aims to: Update the IEAGHG R&D programme CO2 sources database with all the major current and planned industrial sources of CO2 in India, Pakistan and Bangladesh (the updated CO2 sources database is available from the IEAGHG R&D Programme); Identify the CO2 storage capacity of each of these three countries in oil and gas fields and coal seams and ranks the sedimentary basins in India, Pakistan, Bangladesh and Sri Lanka in terms of their saline aquifer CO2 storage potential (sedimentary basins north of the frontal thrusts of the Himalayas were not investigated); Identify the local costs of the main elements of the CO2 capture and storage chain, such that they could be used to produce marginal CO2 abatement cost curves in a future project; Provide a geological CO2 storage potential GIS of India, Pakistan, Bangladesh and Sri Lanka.

3rd Risk Assessment Network Meeting Report

1 March 2008
Event Proceedings
Storage

The purpose of the network is to bring together the key groups working on risk assessment for CO2 storage from around the world and to address what the regulators are expecting in regard to CCS assurance and whether risk assessment can provide the answers they require. This report provides a summary of the third risk assessment workshop hosted by Imperial College in London, UK between the 15th and 16th August 2007.

Assessment of Sub Sea Ecosystem Impacts

1 March 2008
Storage

This report looks at the potential impacts of leaks from a subsea CO2 storage project.It addresses the use of natural analogues, and estimates the relevance of potential CO2 storage leaks against the effects from natural analogues. It highlights knowledge gaps that exist, and also indicates any species that could be particularly vulnerable to CO2 leaks from storage operations.

4th Monitoring Network Meeting

1 March 2008
Event Proceedings
Storage

This is the 4th meeting of the IEA Greenhouse Gas R&D Programme (IEA GHG) Monitoring Network. Since the inception of the Monitoring Network a significant amount of work has been done in this field. There are now a great number of very elaborate CCS demonstration projects occurring worldwide with each one developing and testing new monitoring techniques. While this is happening there is also a great drive from many Governments to put in place the regulations needed to properly licence and supervise CCS activities. This meeting hoped to review where we are with both aspects of CCS and identify what questions still need to be answered.

2nd Meeting of the Risk Assessment Network

1 August 2007
Event Proceedings
Storage

The meeting continued the progress made at launch network meeting in developing our understanding of the status of risk assessment in its application to CCS and developing the role that risk assessment can play.

Potential Impacts of Leaks from Onshore CO2 Storage Projects on Terrestrial Ecosystems

1 July 2007
Storage

The aim of this study was to assess the extent of information currently available on the effects of CO2 seepage on on-shore ecosystems. The objective of the study was to assess what gaps in knowledge exist and what further research needs to be commissioned to address these gaps. The need for this study was first identified by the International Research Network on Risk Assessment in 2005 (for further information, please see www.co2captureandstorage.info). The study was aimed to complement a broader study that was underway that assessed the current Environmental Impact Assessment (EIA) and Strategic Environmental Impact Assessment frameworks for use with CCS . One of the gaps identified by this study was the need for further research on the environmental impacts of CO2 on on-shore environments.

3rd Monitoring Network Meeting Report

1 June 2007
Event Proceedings
Storage

The third meeting of the monitoring and verification network met in Melbourne, Australia over 3 days in October and November 2006. The meeting’s objective was to provide an integrated set of monitoring and verification (M&V) guidelines to encourage further public, regulatory and technical community discussion for wide scale deployment of CCS technology. The objectives were realised by addressing the questions:   <ul> <li>What is the framework of a Monitoring, Evaluation, Reporting and Verification (MERV) protocol for wide scale CCS deployment?</li> <li>How do we provide assurance of storage integrity through well, seal and containment monitoring technology?</li> </ul>   The meeting brought together national and international government regulatory agencies, non-government organisations and Monitoring and Verification (M&V) technical communities in an intensive series of workshops. It was followed by a field visit by train to the site of the CO2CRC Otway Basin Pilot Project (OBPP) in South West Victoria.

3rd Well Bore Integrity Workshop

1 May 2007
Event Proceedings
Storage

The third meeting specifically aims to demonstrate that research has helped to move the technology towards widespread implementation by identifying and understanding the technical barriers encountered while working to address and neutralise these barriers, and also to provide a platform for dissemination of results, information and observations from field and laboratory experiments / measurements. The meeting will also aim to determine what next steps are needed in order to progress the technology even further, into the arena of large-scale demonstration projects.

Environmental Assessment for CO2 Capture and Storage

1 March 2007
Capture
Storage

This report examines the frameworks for Environmental Impact assessment in use around the world and how adequate they will be for application to CCS projects. It also reviews the gaps in the knowledge which will be required to carry out effective assessments and projects future trends in the scope and application of EIA. Requirements for an internationally applicable framework for CCS projects are outlined.

Role of Risk Assessment in Regulatory Frameworks for CCS

1 February 2007
Policy & Regulation
Storage

One of the key issues that need to be resolved for wide scale implementation of CO2 capture and storage (CCS) is that of security of storage. To gain general acceptance of the technology it will be necessary to prove that CCS is a safe and environmentally acceptable option. To resolve this issue it is considered that no single activity or action will satisfactorily answer the question alone. However, a number of different activities when taken together should be able to resolve it

Remediation of Seepage from CO2 Storage Formations

1 January 2007
Storage

The aim of this study was to assess what remediation techniques and approaches are available if seepage of CO2 is identified from a geological storage formation. The objective of the study was to develop a report that can act as a reference manual for IEA Greenhouse Gas R&D Programme (IEA GHG) members in their discussions with policy makers. The report sets out the remediation plan that can be adopted in the event of any seepage being detected based upon different types of seepage event and their associated remediation methods. This report also estimates the costs of different remediation measures.
