Current and Future Applications of Distributed Acoustic Sensing as a New Reservoir Geophysics Tool

Abstract

Distributed Acoustic Sensing (DAS) is a novel technique with low cost, no production deferment, complete coverage and repeatability for seismic data acquisition in vertical seismic profile (VSP), hydraulic fracturing monitoring, well and reservoir surveillance and micro-seismic detection. In this paper, we give a review on the field applications of DAS and the corresponding pre-processing methods as well as the limitations that hinder its further applications in exploration and production. Finally, future developments for DAS are discussed, including the enhancement of S/N ratio, precise determination of receiver channels in depth, rapid processing of massive data and integrated interpretation of multi-mode optical fiber.
