Distributed Acoustic Sensing (DAS) for Reservoir Monitoring with VSP

Abstract

Distributed Acoustic Sensing (DAS) is a novel technology for seismic data acquisition, particularly suitable for VSP. It is a break-through for low-cost, on-demand, seismic monitoring of reservoirs, both onshore and offshore. We will briefly explain how DAS works, and then, demonstrate its usability for typical VSP applications such as checkshots, imaging, and time-lapse monitoring. We will show data examples from around the world, and discuss DAS as an enabler for full-field seismic monitoring with 3D VSP.
