Abstract
There are described methods, systems, and computer-readable media for detecting events in a conduit. Multiple lengths of optical fiber positioned alongside a conduit are used to detect a signal. For each length of optical fiber, interferometric data is obtained from the detected signal. The interferometric data obtained for one length of optical fiber is compared to the interferometric data obtained for one or more other lengths of optical fiber. Based on the comparison, it is determined whether the signal originated from the conduit.
