Abstract

Carbon Capture and Storage (CCS) technology is recognised as an important contribution to mitigate climate changes, and monitoring of the injected carbon dioxide (CO2) is an important element of this technology to ensure that the CCS system operates within the required legal and regulatory standards. To be able to offer more flexible monitoring solutions, the potential of mini streamers for overburden and shallow CCS monitoring has been investigated. The results from a series of 2D and 3D mini-streamer operations across the Sleipner CO2 storage site are assessed and compared with conventional streamer seismic. The results show a clear enhancement in overburden imaging and higher detail at the CO2 plume level compared to conventional streamer seismic data. However, the mini streamers also come with limitations related to the acquisition configuration (for example limited fold, offset, etc.).
