The work is devoted to the development of geoseismic criteria for reservoir quality prediction in J1 Horizon in the south-eastern regions of the West Siberian petroleum basin (Tomsk and Novosibirsk province), where more than 100 oil and gas fields are discovered. Callovian-Upper Jurassic sequence is of the most interest in the context of oil and gas occurrence in the south-eastern West Siberia. Over the large areas of south-eastern West Siberia, the Callovian-Upper Jurassic sequence is represented by the Vasyugansky Fm; it was mainly formed in the marine environment. Towards the margins of the West Siberian sedimentary basin, the Vasyugansky Fm is replaced by predominantly continental and lagoonal facies. The paper discusses the impact of thickness changes of the formations lying between the coal bed U1 and the Bazhenov Fm on seismic wavefield pattern. Analysis of the available data allowed defining geoseismic criteria of the Upper Jurassic deposits transition from marine to continental type. Considering the defined criteria, results of wavefield amplitude analysis and mathematical modelling, a series of composite seismic sections running across the south-eastern West Siberia in roughly WE and NS trending directions was created. Taking into account all the available geological and geophysical information, integrated approach to seismic data, deep drilling data interpretation, wavefields mathematical modelling make it possible to solve sophisticated problems of section geological prediction and to map structurally complicated oil and gas targets.

Key words: Upper Jurassic; Vasyugansky, Naunaksky, Tyazhinsky, Georgievsky, Bazhenov, Maryanovsky and Maksimoyarsky formations; sand level; reflection horizon; hydrocarbon deposits; oil and gas targets.
