FIELD: complex search for oil-gas pools by geophysical methods, in particular, by seismic prospecting and gravitation prospecting. SUBSTANCE: according to the data of gravimetric survey, determined are the plan position and outlines of local geodynamic zones that gravity anomalies; seismic survey is performed within the outlined zones; and, according to the seismic record anomalies, sections are picked out that are featured by enhanced speed and/or density characteristics relative to enclosing rocks at their constant lithological composition. EFFECT: facilitated procedure.
