5th International Workshop on Offshore Geologic CO₂ Storage

• 17 October 2022
• Event Proceedings
• Storage

This 5th Workshop on Offshore Geologic CO₂ Storage covered multiple subjects, including: summary of multiple CCS projects worldwide, subsurface considerations for depleted hydrocarbon fields, containment/ pressure management, and saline formations to store CO₂, as well as considerations on regulating offshore CCS, monitoring offshore CCS projects, CO₂ shipping and infrastructure for CO₂. Importantly, this is the first hybrid in-person and virtual workshop, which represents a milestone to bring this knowledge sharing to multiple people interested on CCS worldwide

Applying ISO Standards to Geologic Storage and EOR Projects

• 1 September 2022
• Policy & Regulation
• Storage

The work aims to summarise and synthesise the two ISO Standards relevant to the geological storage of CO₂: – ISO 27914:2017 (‘Carbon dioxide capture, transportation and geological storage - Geological storage’) and ISO 27916:2019 (‘Carbon dioxide capture, transportation and geological storage - Carbon dioxide storage using enhanced oil recovery (CO₂-EOR)’) – to provide a high-level understanding of the content into an easily digestible format. By comparison with international regulatory frameworks, and providing case studies of how applicable the standards are to real CO₂ storage projects, the study provides a comprehensive overview and concludes on the usefulness of the documents in supporting the implementation of CCUS projects. For the purposes of this overview, the standards will hereafter be referred to as ISO 27914 and ISO 27916

This webinar heard from panellists on the Northern Lights project, the Porthos project, California experiences with permitting and Oxy's recent project experiences. The webinar attracted an audience of 138 in addition to 8 panellists and 2 IEAGHG staff.

Global Storage Capacity Workshop 2021

• 18 February 2022
• Event Proceedings
• Storage

The aims of this workshop were to review current methodologies and initiatives for quantifying CO₂ geological storage, review current data availability and assess gaps, establish core international contacts and a community with direct interest in CO₂ storage resource. The workshop also discussed opportunities on how to address the identified data gaps in various parts of the world, through either bilateral or multilateral collaboration and via an international network to collate and refine estimates of CO₂ storage capacity.

Criteria for Depleted Reservoirs to be Developed for CO₂ Storage

• 1 January 2022
• Storage

In this review we consider advantages and disadvantages of using depleted fields in comparison to deep saline reservoirs as carbon dioxide (CO₂) storage sites. The study consists of three parts. The first looks at ten case studies with operational experience and the insights they offer. The second presents original research on three factors that may impact evaluation of depleted field storage opportunities: 1) the impact of reservoir pressure depletion on storage capacity prediction; 2) the effect of residual hydrocarbons on capacity and injectivity; and 3) the net economic benefit of inherited hydrocarbon infrastructure, including elements that are reusable and those that are not. The third section is a discussion of criteria for evaluating depleted fields for CO₂ storage.

Current State of Knowledge Regarding the Risk of Induced Seismicity at CO₂ Storage Projects

• 1 January 2022
• Storage

The primary objective of this study is to summarize the levels of induced seismicity observed in or near CO₂ storage sites, and the consequences of the induced seismicity in terms of impact on people, as well as the environment, assets and reputation of operators, authorities, and on CCS technology. A second objective is to gain an understanding on processes that industry and authorities employ to manage the risk of induced seismicity. A third objective is to present notable case studies where outreach measures have supported operators and regulators in managing concerns of stakeholders in connection with induced seismicity. The final task of the study is to identify current research and innovation trends to better manage the risk of induced seismicity.

IEAGHG Monitoring Network - ‘Monitoring Expertise Showcase for Post-Closure Monitoring’

• 23 April 2021
• Event Proceedings
• Storage

This was a little different from usual webinars, whereby the Steering Committee aimed for a more interactive and informal experience for the audience with a scenario-based exercise.<br />Susan Hovorka (<em>BEG at UTexas</em>) introduced the hypothetical site scenario. She emphasised that the aim of the event was to learn about post-closure monitoring options, with an informal ‘game’ to engage panellists with the audience in thinking about CO₂ storage sites and measurement, monitoring and verification (MMV). This is a hypothetical site with some gaps in the information, in reality the site characteristics would be much better understood for storage projects and months of planning would have been done prior to making any sort of decisions on monitoring programmes. The hypothetical site scenario is described in figure 1, below. This ‘site’ will be injecting for 25 years, into 50 metre thick sandstone at a depth of 1.5km.

Exporting CO₂ for Offshore Storage – The London Protocol’s Export Amendment and Associated Guidelines and Guidance

• 12 April 2021
• Policy & Regulation
• Storage

The London Convention and London Protocol are the global treaties that protect the marine environment from pollution caused by the dumping of wastes. Since 2006, the London Protocol has provided a basis in international environmental law to allow carbon dioxide (CO₂) storage beneath the seabed when it is safe to do so, and to regulate the injection of CO₂ into sub-seabed geological formations for permanent isolation. However, Article 6 of the London Protocol prohibits the export of waste or other matter for dumping in the marine environment. Therefore in 2019, Contracting Parties to the London Protocol adopted a resolution to allow provisional application of the 2009 amendment to Article 6 of the Protocol to allow export of CO₂ for storage in sub-seabed geological formations in advance of its ratification, which was progressing slowly.

This discussion panel was held by webinar on Wednesday 12th August at 10pm BST, with the theme of engaging regulators, looking at ‘Regulation, Industry and Research - Translating Monitoring Research to Meet Commercial Needs’. The panellists comprised different CO₂ storage monitoring stakeholders; operators, regulators and researchers and attendees were asked to submit questions for the panellists to consider prior to the event, of which over 120 were received. 70 participants joined the event, in addition to the 8 panellists involved.The aim of the panel was to discuss the translation of CO₂ geological storage monitoring research into regulations and commercial-scale projects. It began with a scene setting presentation and framing questions with in-depth and thoughtful discussion with operator, regulator and research representatives from the US, Australia, and Norway.This discussion panel was an ideal opportunity for all stakeholders actively engaged in CO₂ geological storage projects and practical research in monitoring to share and learn about how the information from research and our Monitoring Networks can be used to meet commercial needs.
