Summary
Exhibiting for the first time this year is Spectraseis, established in 2003 as a spin-off from Zurich University. They have developed a new type of passive seismic method leveraging the low frequency ambient waves that are present everywhere in the Earth’s crust, continuously generated by natural events such as ocean wave movements and micro-tectonic activity. Until now, this part of the frequency spectrum was systematically disregarded as noise. Spectraseis analyzes the modifications of the background wave spectrum which occur when low-frequency waves propagate through hydrocarbon-bearing reservoirs. By identifying specific spectral signatures of the interactions between the reservoir rock and its fluid content, HyMAS provides direct hydrocarbon indication. By focusing on hydrocarbon content rather than structure, HyMAS has the potential to answer questions that other geophysical methods cannot.
