The technology of passive adsorption of hydrocarbon of bottom soil air through the modules - sorbers allows to get geochemical maps of the forecasting hydrocarbon deposits distribution probabilities, which is a direct method of prospecting and exploration of oil and gas fields with high reliability (up to 90%) on the base of interpretation of the soil gases sampling data, which are the key to interpretation of the ascending gas emanations. Relatively simple and inexpensive technique is used in almost all oil and gas regions of the world to select the objects of exploration drilling and the optimal location of producing wells. The results of the geochemical work at Shuginskiy site of Yarudeyskaya area of Nadym region of Western Siberia are presented.
