Abstract

Summary

Collecting Distributed Acoustic Sensing (DAS) data with multi-mode (MM) optical fiber is a challenge but not impossible. This paper presents the effect of MM fiber on DAS data for several oil and gas applications. These include borehole seismic surveying and downhole flow monitoring. The business need to acquire DAS on MM is high given the considerable installed base of MM fiber. This MM fiber was originally installed for Distributed Temperature Sensing (DTS) and communications. However, it is now possible to re-purpose this fiber for DAS acquisition, making a considerable saving over the installation of a new fiber. We present promising results acquired using this approach.
