Course Credit: 0.15 CEU, 1.5 PDH

CCUS is a key component in the efforts to achieve globally agreed climate targets. In 2018, the chair of the International CCUS Summit stated that, “…availability of safe, secure and adequate CO2 storage is a prerequisite for investment in both transport and storage infrastructure…”. With an expected global expansion in CCUS sites, it is worth considering how existing tools, techniques, knowledge and expertise can help understanding and reduce risk in planning and decision-making for those sites. Core analysis is one such existing tool. It has been described as the “foundation of formation evaluation” and should be an essential part of any feasibility study to verify a storage site as being adequate, safe and secure.

Some questions that should be asked are: what is “adequate, safe and secure” for a specific storage site? what data is necessary to verify this? are there data already available? what information is lacking due to little or no previous investigation? what is the impact of CO2 on the system? is it time-dependent? are there detrimental effects of injecting CO2? what specific core analysis techniques can be used to study this?

For many years, the oil & gas (or energy) industry has used core analysis to improve development decisions by studying subsurface systems to better understanding the lithological, petrophysical and fluid dynamic properties important to production. It’s been used to investigate and help determine mitigation plans for issues of formation damage on productivity and injectivity indices. Carbon dioxide injection has been studied and employed as an enhanced recovery method but almost always with the aim of recovery rather than storage.

This presentation will highlight some of the key required information, the analyses to provide it and show its use in characterising, understanding, and executing CCUS projects. This will be illustrated with CCUS case studies where possible, and subjects will include petrography, fluid analysis, petrophysics, formation damage, rock mechanics and dynamic properties. Significant knowledge and data already exist around geological reservoirs, and this presentation aims to introduce and highlight what can be used to reduce risk, improve carbon injectivity & add value in CCUS projects.
