The paper presents innovation technology test results of spectral analysis of microseisms (SAM) on 2D CDP seismic survey carried out in the Shushukskaya area (Krasnoyarsk Territory). The SAM technology is based on the analysis of space-time CDP seismogram intervals to the first arrivals of induced waves, which allows for receiving additional characteristics of emission waves. We discuss the geological features of the Shushukskaya license site which in complexity and conditions of work can be considered typical of the Lena-Tunguska petroleum province where the efficiency of seismic survey is difficult to be recognized satisfactory. Longstanding seismic exploration operations and appraisal drilling have resulted in the discovery of a new oil field with non-commercial flows of oil. The SAM technology has made it possible to process data of 41 profiles 2 477 linear km in total length, to reveal five anomalies of emission wave intensity which can be assumed promising for further geological exploration (GE). A high priority target is the Shushukskaya-2 anomaly located in the northwest of the area which is observed on ten profiles and is about 200 sq. km in area. Total resources of conventional HC make up about 375 million m3, i. е. a large and highly productive oil and gas field would be expected to be discovered here. The next exploratory well is localized. It is recommended that GE paradigm be improved in anomalously complex seismic conditions of East Siberia using innovation technologies of direct forecasting of HC pools. It is advisable to reprocessed SAM data on regional profiles as well as materials of seismic survey performed on fields with non-commercial flows of oil.

Key words: SAM innovation technology, Shushukskaya area, geodynamic noise model, promising targets, GE paradigm.
