Abstract

There is herein described, a method of Distributed Acoustic Sensing, the method comprising transmitting an optical sensing signal into an optical fibre located in a channel, measuring an intensity of a return signal, the return signal comprising a component of the optical sensing signal that has been backscattered from a target location in the optical fibre, performing a comparison of the measured intensity of the return signal to a threshold, if the comparison indicates that the intensity of the return signal is greater than the threshold, determining that a blockage may be present in the channel in the vicinity of the target location.
