Abstract

The paper presents new paleotectonic data on the Bovanenkovo, Taz, and Gubkin dome-shaped uplifts and the Novyi Port, Urengoi, Kharampur, and Medvezh'e swells, with implications for the history of zone J2 and the Jurassic reservoir as a whole. Most of the large uplifts originated in the Early-Middle Jurassic and completed their evolution in the early Late Cretaceous (latest Cenomanian), generally (Bovanenkovo, Novyi Port, Kharampur, and Taz) or to a large extent (Urengoi and Gubkin), except for the much younger Medvezh'e swell, which formed in the Paleogene-Quaternary interval. The conditions for oil storage and retention in anticlinal traps of Jurassic zones J1 and J2 were the most favorable between the middle Late Cretaceous and the Eocene, inclusive. Gas accumulation lasted for a much longer time, from the Late Jurassic to the Present, and was especially rapid in the Late Cretaceous-Paleogene.
