Abstract

Summary

Time-lapse seismic is the main method in monitoring as well as the industrial-scale carbon capture, utilisation and storage projects. To properly plan a 4D seismic strategy, the appraisal of the geometry, source/receivers positioning, near-surface conditions and seasonal variations, different sources or receivers is crucial to be tested in various geological settings. The South West Hub area has been investigated for its potential of future industrial-scale carbon capture, utilisation and storage projects. In-Situ Laboratory Project was conducted in this area as a small-scale test site which would determine the approach to be taken for larger commercial CO2 geosequestration projects. The monitoring of controlled injection of a cumulative 38 tonnes of CO2 is conducted utilising the application of TL vertical seismic profiling using distributed acoustic sensing in the wells. In this presentation, to assess these key factors, we present the results of the repeatability analyses conducted on the data after the time-lapse processing.
