... reopening, we collected Bottomhole Pressure (BHP) and salinity, surface tiltmeter, and Distributed Acoustic Sensing (DAS) data. We analyze the DAS slow-strain data to assess fluid arrival time, pore pressure diffusivity, and HF reopening toward each DAS-fiber well. Four observation wells at the DFPS, 75 ft...

.... It was found that although Stage 4 fracture approaches closer to the fiber, it does not intersect with well 16B, whereas Stage 5 fracture easily intersects with well 16B and it can be identified from the fiber readings. Additionally, it was discovered that a closing of a fracture that is closer to the fiber...

... in an elastic formation. However, in many instances (e.g., geothermal reservoirs and fault motion monitoring) the deformation mode is shear on natural fractures, but the resulting fiber signature has not been studied. In this work we use a 3D poroelastic hydraulic fracture model to obtain strain signatures...
