Abstract
2003, a group of scientists in Switzerland set out to answer some intriguing questions with implications for the way oil and gas reserves are discovered and produced. Research conducted by Dr. Stefan Dangel at the University of Zurich had highlighted a strong and consistent empirical relationship between low-frequency spectral anomalies in seismic background wavefields and geological characteristics of a collection of reservoirs, mainly in the Middle East. Similar observations have also been reported in the Russian literature since the early 1990s.
