Seismic Signal Denoising and Decomposition Using Deep Neural Networks [PDF]
Frequency filtering is widely used in routine processing of seismic data to improve the signal-to-noise ratio (SNR) of recorded signals and by doing so to improve subsequent analyses.

Non-Contact Water Level Response Measurement of a Tubular Level Gauge Using Image Signals
The occurrence of excessive fluid sloshing during an earthquake can damage structures used to store fluids and can induce secondary disasters, such as environmental destruction and human casualties, due to discharge of the stored fluids. Thus, to prevent

Seismic attenuation in Faroe Islands basalts [PDF]
We analysed vertical seismic profiling (VSP) data from two boreholes at Glyvursnes and Vestmanna on the island of Streymoy, Faroe Islands, to determine the magnitude and causes of seismic attenuation in sequences of basalt flows.

Time-lapse seismic attenuation as a tool for monitoring hydrocarbons and CO2 in geological materials [PDF]
Both laboratory experiments and theoretical models have shown seismic attenuation to be sensitive to various petrophysical properties of rock and pore fluids, making attenuation a potentially useful time-lapse attribute to measure and interpret through ...
