FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises drilling the wildcat well and recording of data signal from drilling zone. Note here that said data signal represents electromagnetic radiation caused by bed material destruction by drill bit to compare obtained spectrum of signals with premade spectra of destruction of materials containing the known amount of hydrocarbon stock. In case said spectra are alike hydrocarbons are considered available in the bed. Besides, signal originating in drill bit volume is recorded by radio antenna located on the surface while said rill bit is isolated from casing pipe.
EFFECT: simplified and valid process and device.
