The Passive Seismic uses the environmental seismic vibrations to identify sites with hydrocarbon reservoir (oil and gas) as shown in the video below.
The Figure below show a example of anomalies in the spectra of environmental seismic vibrations carried inside (red line) and outside (blue line) the limits of a known oil reservoir (Graf et al. 2007).
Passive Seismic is a core service offered by VERACRUZ, and we have renowned researchers in this field. Contact us to schedule a meeting to talk about the method, its strengths and weaknesses, and how it can benefit your project.
