Prospects of oil and gas potential in the northern flanks of the Onon depression (Transbaikalia) according to electromagnetic sounding and gas chromatography data

Abstract
Electrical prospecting and geochemical studies were conducted in one of the intermontane depressions of Transbaikalia to assess its oil and gas potential. For many years, this area has been considered to have low hydrocarbon prospects. Recent field studies have revealed intensive butane concentration anomalies in rocks of the upper section. Layers with improved reservoir properties were identified based on electromagnetic sounding data. The assessment of forecast resources and recoverable natural gas reserves indicated the possible presence of a medium-scale gas field and a large-scale oil field, in terms of recoverable reserves, in the studied area.
