Sustainability Assessment Review of Application of Microtremors for Detecting and Studying Hydrocarbon Reservoirs

Notwithstanding geological and geophysical surveys and studies for hydrocarbon reservoir detection cost very much, those have lots of uncertainties. Then, engineers and scientists try to find and use new methods. Recently, some studies have suggested using ambient noise as a tool for hydrocarbon reservoir investigation. This new passive seismic technique, named HyMas, is based on the positive energy anomaly in data spectra between 1 to 6 Hz for microtremor measurements over reservoirs, which are called hydrocarbon microtremors. Despite the acceptable results obtained by the HyMas technique, there are many unknowns, especially concerning the source and generation mechanism of hydrocarbon microtremors and the relations between reservoir characteristics and the attributes of hydrocarbon microtremors. In this study, it has been tried to review the published experiences and studies and conclude the results and findings.
