The results of litho-bio-stratigraphic studies of Callovian and Upper Jurassic of the Em-Ega oil field (Western Siberia) are presented. The formation of sediments took place in the sea basin and had a pulsating character. Episodes of sediment accumulation were replaced by periods of a sharp shortage of terrigenous material. The main stages of the arrival of terrigenous material were Callovian, Middle and Late Oxfordian, Early Kimmeridgian and Middle and Late Volgian. In Early Oxfordian, Late Kimmeridgian, Early Volgian deposits did not accumulate.
