Abstract

A new technology to identify and delineate hydrocarbon structures by analyzing different non-linear seismic effects has been developed. In contrast to traditional seismic methods this technology uses non-linear model of the media which takes into account seismic non-linearity of the natural gas and oil reservoirs allowing distinguishing them from surrounding rocks. This technology bases on two main non-linear effects which observed in hydrocarbon reservoirs:<br>- non-linear behavior of registered signal amplitudes comparative to emitted signal amplitudes.<br>- oscillations with multiple, combinative – summarized and differential - frequencies appear in the reservoir; <br>Vibroseis method is chosen to investigate a non-linearity of geological environment because it allows efficient choosing, analyzing and controlling source signal.<br>
