Wellbore Integrity Network
A network to identify the integrity of wellbores, in particular their long-term ability to retain CO2, as a significant potential risk for the long-term security of geological storage facilities.
The aim of the network is to further the understanding of the issue of wellbore integrity in general and begin to attempt to develop answers to the main issues and problems identified.
The network set itself the goal of addressing the following key three issues:
During the development of the Risk Assessment Network, discussions highlighted that the integrity of wellbores could be a significant potential risk for the long-term security of geological storage facilities.
An inaugural workshop was held in 2005 to bring together over 50 experts from both industrial operators and from research organisations to determine the current state of knowledge of wellbore integrity.
Ensuring well integrity over long timescales (100s to 1000s years) has not been attempted before and therefore represents a new challenge to the oil and gas industry. One conclusion from the inaugural workshop of the Wellbore Integrity Network was that it will probably not be possible to promise a leak-free well since it is well known that conventional Portland cements are degraded by CO2. Rather, the emphasis should be on designing wells employing state-of-the-art technology which should reduce the risk of CO2 release.
Meeting and Summary Reports
Summary reports from previous Network workshops are available, together with information on the next workshop.
The 2nd IEAGHG Joint Network Meeting will be held on the week of the 18th June 2012 in Santa Fe, New Mexico, hosted by Los Alamos National Laboratory. This meeting will include all four of the geological storage networks (Risk Assessment, Modelling, Monitoring and Wellbore Integrity)
Further details will be available shortly. Registration for this meeting will open in February 2012.

Membership of this network is open to individuals with a professional interest in Wellbore Integrity for CO2 Geological Storage.
