AGR's Lead Geophysicist to present a paper on Carbon Capture Storage (CCS)
Peter Rowbotham, Lead Geophysicist at AGR, will present a paper on subsurface monitoring aspects of CO2 storage at DEVEX 2015.
The paper "Subsurface monitoring aspects of CO2 Storage in a Saline Aquifer" was co-authored by AGR and National Grid Carbon professionals Peter Rowbotham (pictured), Steven Furnival, Craig Webster, Iulia Wright, Alastair Brown and Rohan De Silva.
UK Carbon Capture and Storage (CCS) projects need to demonstrate through monitoring that the injected CO2 is contained within the geological store during and after injection. This requires verification of well and reservoir integrity, and comparison of actual versus modelled CO2 migration.
Metering of injected CO2 is clearly mandatory, but once the CO2 has passed the perforations and entered the storage formation, geophysical monitoring methods must be employed. National Grid Carbon (NGC) is working with the Don Valley CCS Project and with Capture Power Limited (White Rose CCS project) who are developing new power plants with carbon capture near Hatfield and at Drax, respectively. A storage site in the Southern North Sea (SNS) has been selected. White Rose is one of two full chain commercial scale demonstration projects selected for potential funding support from the UK Government CCS Commercialisation Programme.
The paper presents a review of applicable monitoring technologies for the case study of CO2 injection into a large saline aquifer structure in the UK SNS. Following feasibility studies, time-lapse seismic and microseismic are key geophysical technologies for plume migration and integrity monitoring, respectively. These together with in-well monitoring are expected to form the basis for a subsurface monitoring plan.
