Distributed fiber optic sensing offers several benefits over conventional technologies for well integrity and production monitoring. Continuous acquisition from all points along the instrumented well path means that events and features can be captured without the need to place point sensors at the right depth at a specific time. This allows the whole well to be logged simultaneously, allowing for events to be verified over an extended period of time (repeatability). It also permits the stacking of data to enhance the response of continuous phenomena. Finally, it allows for the detection of intermittent phenomena that may be missed during time-sensitive methods of acquisition (e.g. wireline).
