Optimizing Distributed Sensing Measurements in Multi-Well Acquisition

Distributed Sensing measurements are increasingly being used to make measurements in both the near and far field. The quality of the signals recorded by DAS systems are sensitive to the choice of optical settings used by the Interrogator Unit. Here we show examples of data recorded in various modes and the impact it has on the overall DAS project. By using data from multiple wells instrumented with fibre we show the impact of optical settings from very different vantage points. We show how both engineering and geoscience measurements can be made while still providing good SNR or resolution. We show how multiple wells can greatly enhance the nature of the physical processes that can be monitored with fiber optic. Our aim is to show the impact of optical settings in the various monitoring modes that can be taken with DAS.
