The UK has a number of storage sites already licensed, but modelling by the Carbon Capture and Storage Association shows that the currently licensed sites will be full by around 2030 and also it takes 7 years of geophysical work to get a license for a new one. The UK is not short of space but it takes a long time for the necessary studies. We will review the geophysical workflows involved in appraising new CO2 storage sites.

We will look at the "North Sea Transition Deal" agreed with UK oil and gas operators and the UK government, under Offshore Energies UK (formerly Oil and Gas UK) and what it means for CO2 storage and geoscience.

We will explore how the mindset of the exploration geoscientist is required to generate CO2 storage assessments and plan injection operations - including making a seal assessment, CO2 fluid flow dynamics (which are analogous to hydrocarbon migration), understanding geological heterogeneities (facies and structures). Also creative thinking, management of uncertainty, and working with data scarcity.

Geophysics skills can also be useful in monitoring what is happening with CO2 after being injected in the subsurface. Where is it going and is there any risk of a leak. Fibre optic cables in wells can gather acoustic data which can be analysed, and reveal a great deal. But it also involves geophysical expertise.

Why are Geoscientists so key to the successful deployment of the sector?

Chris joined the Carbon Capture and Storage Association in January 2019 after five years working as a Deep Subsurface Geoscientist at the British Geological Survey.

During his time at the British Geological Survey, Chris specialised on offshore CO2 storage site appraisal in the North Sea and East Irish Sea Basins. Chris brings a strong technical understanding of the geological aspects of CCS to the secretariat and is passionate to ensure that strong policy frameworks can be introduced to accelerate CCUS deployment across the UK and Europe.

Geological Storage of CO2: A New Role for Exploration Geoscientists

Talk Description
To request slides for this presentation, contact Karl Jeffery on

In most CCS operators, storage and CO2 plume assessments are often placed under the responsibility of the company's production team (production geologists and reservoir engineers) based on the assumption that the CO2 operation is a reservoir scale operation requiring the same skills as E&P production.

This talk argues that, especially for saline aquifer storage opportunities, the mindset of the exploration geoscientist is required to successfully generate CO2 storage assessments and plan injection operations. The key skills the explorationist can bring include dealing with data scarcity, generating seal assessment (not purely focusing on the reservoir flow units), CO2 fluid flow dynamics that are more analogous to hydrocarbon migration than production, the importance of geological heterogeneities (facies & structures), creative thinking and management of uncertainty.

Advances in Distributed Acoustic Sensing (DAS) monitoring for CCS projects

Watch Video    View PDF   
Talk Description
Distributed Acoustic Sensing is done using fibre optic cables in wells, which act as microphones, recording sound made in the well and reservoir as the CO2 is injected.

By analysing this acoustic data, it is possible to get a picture of where the CO2 is travelling to in the reservoir, and ensure it is staying there.

This technology is being increasingly used in CO2 storage sites around the world, including in Australia and Canada. The talk will explain how it is being used and how it works

  • Developing an integrated approach to monitoring

Since leaving the Royal Navy, Rob has specialised in offshore energy, in both conventional oil and gas and overseeing large projects in site characterisation and asset integrity for Carbon Capture Utilisation and Storage (CCUS). He was the lead for the Energy Technologies Institute store monitoring programme and has recently been working with the IOGP to develop their shallow monitoring guidelines. Rob is the Principal Advisor for CCUS at the geophysical and geotechnical consultancy Inosys Ltd, he is published on the subject and speaks regularly at conferences.
