Active seismic methods are playing an important role in monitoring of changes in the subsurface due to reservoir production or CO2 geosequestration. However relatively high cost, high level of invasiveness triggering land access issues and significant time delay between data acquisition and availability of the interpretable results impede use of 4D seismic method. One of the ways to address these issues is to utilize permanently deployed receiver arrays for active monitoring as they decrease the land impact and speedup acquisition and processing. Recent advancements in distributed acoustic sensing (DAS) technology makes fiber-optic cables becoming a key component of such receiver arrays, including those deployed in the wells. In this presentation we evaluate applicability of passive VSP DAS for seismic imaging and monitoring using data from Curtin/NGL training well facility.
