Experience in Low-Frequency Spectral Analysis of Passive Seismic Data in Volga-Ural Oil-Bearing Province

In this paper, we consider our experience with passive low-frequency seismic exploration for oil and gas. We present the<br>data on the phenomenology of the effect, sets out possible geophysical mechanisms of effect, present results of numerical<br>simulations in comparison with the observed results; we describe the main approaches to the interpretation of seismic data<br>studies and give a brief overview of geological results of our microseisms research in the Volga-Ural oil province.
