Cemented fibers as a testbed for distributed acoustic sensing (DAS)
Thomas Forbriger, Felix Münch, Laura Hillmann +6
A rigid connection between the optical fiber and the rock makes amplitudes of 'fiber strain' measured with Distributed Acoustic Sensing (DAS) equal to 'rock strain'. We demonstrate…

Calibration of the strain amplitude recorded with DAS using a strainmeter array
Thomas Forbriger, Nasim Karamzadeh, Jérôme Azzola +3
The power of distributed acoustic sensing (DAS) lies in its ability to sample deformation signals along an optical fiber at hundreds of locations with only one interrogation unit (…
