... storage CO2 plume Usz Ez monitoring, we mimicked a cross-well monitoring setup in a intrusion brine (2) homogenous porous medium, with a seismic source located CO2 in well A, and a series of collocated geophones and (3) electrodes to record seismic displacement and associated, P-wave (1) coupled electric...

... A new pneumatic seismic source with a resonance frequency of 2.8 Hz has been built and tested during an OBN sea trial in the Gulf of Mexico. Data from the new source demonstrates that low frequency refracted signal can be recorded for offsets up to at least 45 km. The low frequency signal from...

The utilization of MSV has proven out concept that the combination of marine environmental-friendly seismic source and the interferometric approach...

... ABSTRACT A novel Eddy-current impact seismic source concept has been simulated and bench-tested. This concept seems suitable for lower cost, shallow seismic surveys due to a relatively simple and low-cost mechanical and electrical structure. The creation and interaction between electrical...

... and engineering applications, several studies have examined various aspects of the methodology, including effects of seismic source, testing configuration, and data processing methods. Theoretically, Rayleigh and Love waves are best generated using vertical and horizontal impacts, respectively. Angled impacts...

Explosives were good sources but were dangerous to their operators and harmful to the environment. When pneumatic sources...
