The article considers a results of complex aerogeophysical survey during prospecting works on diamonds.

The results of the geoelectric methods of forming a short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) used during the aerogeophysical investigation conducted within the area of the Sobynskoye oil-gas condensate field are given. The principal possibility of the survey by the FSPEF method conducted from an airplane is presented. This testifies that FSPEF survey can be used alongside with other aerogeophysical methods for reconnaissance investigation of large areas and difficult for access oil and gas territories. The FSPEF-VERS technology can be successfully used while searching and prospecting hydrocarbon deposits in the complicated tectonic and geological conditions of the Siberian platform.

We take into consideration the issue regarding the heterogeneously magnetized relief of the earth surface and its effect on aeromagnetic survey's results. According to our proposal recounting of the field can be carried out towards a horizontal plane with purport to exclude "anomalous" nature of the terrain. Corrections can be performed by means of solving a direct task of magnetic prospecting for elaborating a digital model of the relief. A new algorithm, which can determine effective magnetization of the rock located in the upper layer of a geological profile is introduced, the basis of which is rapid wavelet transformation. The aeromagnetic survey data obtained on the average scale in the Central Siberia have been processed and submitted.
