Methodological approach to predicting oil and gas occurrence in the Chkalov field (Tomsk region) according to comprehensive interpretation of geological and geophysical information

We present a methodological approach to predicting oil and gas occurrence by the example of the Chkalov field, which is located in the southeast of the West Siberian petroleum basin. The M bed of the Paleozoic weathering crust and the Yu11 bed of the Upper Jurassic Vasyugan Formation contain oil and gas accumulations. Hydrocarbon traps were already formed during the Jurassic stage of the development of the basin. Throughout geological history, the structures remained closed, changing their shape and amplitude insignificantly. According to the comprehensive interpretation of seismic exploration and deep drilling data and basin modeling technology, oil and gas accumulations, as well as a number of prospective oil and gas traps, have been identified. Structural, lithological, and tectonic factors provide hydrocarbon trapping.
