The West Siberian province located within a young plate (platform) is one of the largest in the world in size, reserves, number of unique fields, and hydrocarbon production. The southern, central, and western areas of the province are dominantly oil-bearing, the northern portion gas-bearing. All commercial reserves are within the Devonian-Cenomanian stratigraphic interval. Small accumulations in fractured-vuggy Devon-Carboniferous rocks are located in the zone of unconformity between this sequence and the Jurassic. The potential of the pre-plate middle Paleozoic, platform upper Paleozoic, and Triassic sequences recognized by seismic data in the northern, deepest, part of the plate is not known yet. Most hydrocarbon pools are located in the Jurassic-Cretaceous hydrocarbon-bearing sequences (HBS) within the plate cover. Structural-depositional oil accumulations with very changeable flow rates, a large stratigraphic-depositional accumulation in high permeability basal (quartz) reservoirs, and an oil-condensate and a multiple-pool structural gas field are discovered in the Middle Jurassic composed of potential continental coal-bearing and marine deposits. In most HBS, there is still a prospect of discovering new hydrocarbon pools including pools in more complex traps.
