Distributed Fiber-optic Sensing Laboratory
What is Distributed Fiber-optic Sensing?
- The application of fiber-optic sensing techniques to understand Earth’s subsurface and surface processes, as well as applications in Earth resources and infrastructure.
DFOS is a vital toolkit for long-term monitoring with high spatial and temporal resolution, aiding us in uncovering previously undiscovered problems and gaining insight into enigmatic issues.
(a) shows an example of a DAS recorded raw shot gather generated by perforation. Horizontal axis is the recording time, and vertical axis is the measured depth of the wellbore. Red color indicates the positive amplitude, whereas the blue color indicates the negative amplitude. Both P wave and tube wave are labeled. Panel(b) shows an expanded view of P-wave propagating towards to the pre-fractured (heel-ward) direction. The waveform distorted as it propagates further.
