The article deals with the physical foundations and a set of issues on the technology of seismic location of oil and gas (SLONG) related to the seismic impact on productive formations, their emission of emission waves and the method of their isolation during the processing of seismic profiles of CDP-2D. It is shown that the main effect of seismic impact is the occurrence (growth) of fracturing, in which the radiation of high-frequency vibrations by the formation is associated with the formation of shear microcracks, and low-frequency (relative to the frequency of impact) with plastic deformation of the reservoir sections, accompanied by vibrations from ground-based emitters. The method of processing of seismic materials CDP-2D and the method of isolation of radiation areas by a productive layer of low-frequency emission waves are considered. Examples of processing of six profiles of CDP-2D using the considered SLONG technology are given, which indicate the consistency of the results obtained and the possibility of using them to assess the oil and gas prospects of objects. The possibility of using SLONG to search for non-standard hydrocarbon traps is postulated.
