ABSTRACT
Distributed acoustic sensing for seismic imaging and monitoring
Distributed acoustic sensing (DAS) is a technology allowing use of optical fibre as a seismic sensor by sending a series of laser pulses and analysing the scattered light coming back from different sections of fibre. The technology does have strong disruptive potential in active and passive seismic imaging and, especially, monitoring, as fibre optic cables converted to thousands of receivers can be installed in various locations and used to acquire data continuously for an extended period of time. The cables are slimmer, do not have any active electronic components and can withstand harsh downhole conditions, making DAS attractive in borehole seismic operations. In this presentation, we discuss basics of the technology and illustrate it using several case studies from Australian CCS projects. These includes examples of downhole time-lapse DAS surveys for monitoring of small-scale CO2 injection and leakage detection. We also demonstrate how the distributed fibre optic sensing can be used to transform a well to a permanent receiver array during the abandonment process.
