Abstract

Summary

Acquisition of borehole seismic data using distributed acoustic sensing (DAS) technology is a rapidly developing trend in borehole geophysics. This includes active VSP surveys for the subsurface characterisation and active and passive surveys for reservoir monitoring. While an increasingly popular technique onshore, time-lapse DAS VSP is still relatively rare in offshore environments as, among other challenges, it often requires going through long umbilical cables to the well.

Recently, some solutions to this problem have emerged. For instance, one approach involves adding passive components, like separate cores on tie-back cables, to transmit and receive pulses to and from the sensing fibre.
