Новые данные по перспективам нефтегазоносности верхнеюрских отложений северо-востока Томской области

Geological and geophysical studies of the north-east territory of Tomsk region are currently going on at a regional level. Assessments of its perspectives by various researchers are controversial. A prevailing opinion on low hydrocarbon-bearing potential of the given territory is based on the results of previously performed geological prospecting works that, on the whole, brought no positive results. The paper considers new geological and geophysical data acquired in recent years – regional seismic surveys and reinterpretation of logging, drilling and testing data available for "archived" prospecting wells. Conclusions on possible productivity of Upper-Jurassic deposits in the area of Kosetskaya depression were made following the results of logging and seismic survey interpretation and taking into account latest discoveries made in a bordering territory. Some recommendations on further geological and prospecting operations in the territory are provided considering particularities of its geological structure
