Geodynamical noise of hydrocarbon pools and passive and active seismic CDPM

The information on the technology of passive and active seismic using the common-depth-point method (hereinafter “the PAS CDPM”), solving the problem of direct explorationof hydrocarbon accumulations using the amplitude information of induced geodynamic noise emitted by these accumulations is containing.It is shown that the use of this technology can prevent drilling of nonproductive wells.
Materials and methods
The proposed PAS CDPM technology complexes registration and interpretation of inducedgeodynamic noises emitted by hydrocarbon accumulations, and waves reflected from the seismic horizons. This provides high efficiency of studying of reflectors geometryand registration of induced geodynamic noises emitted by hydrocarbon accumulations.
Results
The PAS CDPM technology tested in dozens of hydrocarbon accumulations of Western and Eastern Siberia has proven its efficiency, namely all accumulations have displayedintensity anomalies of geodynamic noises, and no such anomalies have been observed outside accumulations.
Сonclusions
The above mentioned PAS CDPM technology capability is relevant nowadays, whenthe economic crisis is gathering pace. The defined technology will make it possible for petroleum experts to drill traps instead of drilling structures that will increaseseveralfold efficiency of oil and gas geologic exploration.
