The students, postdoctoral fellows, and researchers of the CREWES project at the University of Calgary are developing an integrated approach to active seismic monitoring of CO2 injection and storage.  The primary issues associated with this problem – controlling costs and understanding uncertainty – have motivated us to do so by employing several recent technical tools: fiberoptic sensing (DAS), waveform inversion, and a range of machine learning architectures.  We have also recently undertaken some unique experiments, including a baseline multi-offset and multi-azimuth VSP, which was carried out in collaboration with the Containment and Monitoring institute (CaMI), at the CaMI Field Research Station in Newell County AB.  The acquisition included a dense array of downhole accelerometers, and both straight and helical-wound fiberoptic cable, deployed to characterize the geology at and above a shallow sandstone formation into which CO2 has now (subsequently) begun to be injected.  In this presentation I will describe this and other recent initiatives of the CREWES project, and show some highlights of the new science emerging from these efforts.
