Distributed acoustic sensing (DAS) is a promising technology for seismic data acquisition, particularly in downhole applications. However, downhole DAS measurements can be affected by the deployment method of the fibre-optic cable. These effects were

Seismic velocities and elastic moduli of rocks are known to vary significantly with applied stress, which indicates that these materials exhibit nonlinear elasticity. Monochromatic waves in nonlinear elastic media are known to generate higher harmoni

Monitoring changes of formation properties along the well bore associated with the presence of carbon dioxide can be important for both tracking the plume inside of the primary containment and detecting leakage into the zone located above the reservo

Field observations show that power spectra of the response to high amplitude harmonic excitation contain peaks at frequencies multiple to the driving frequency, e.g. [1]. This phenomenon is conventionally attributed to the effect of mechanical non-li

Downhole seismic acquired with distributed acoustic sensors (DAS) provides a unique opportunity to record genuinely broadband data with a frequency range varying from sub-milli-Hertz to several kilo-Hertz. As such, downhole DAS is used to detect and

Recent studies use seismic strain amplitudes recorded by distributed fibre-optic acoustic sensors (DAS) to estimate elastic properties of the formation (the stiffer the formation, the smaller the strain). However, borehole DAS response can be affecte

Instrumenting wells with distributed acoustic sensors (DASs) and illuminating them with passive or active seismic sources allows precise tracking of temporal variations of direct-wave traveltimes and amplitudes, which can be used to monitor variation
