pdf  Geological-geochemical criteria of the Anabaro-Khatang saddle petroleum
Geological and geochemical criteria of potentially oil and gas bearing accumulation of the Anabar-Khatangskaya saddle are considered. On the example of the Lower Kozhevnikov Formation of the Early Permian age, the following elements were analyzed: the thickness of oil and gas-bearing rocks and their ontact zones subjected to high-temperature destroying of organic matter under the influence of stratified intrusions; types and catagenesis stage of organic matter; contents of organic carbon and hydrogen index. For the Riphean, Cambrian, Devonian, Permian and Jurassic sequences, a comparative analysis of the distribution of the hydrogen index was carried out. The territory of the Anabar-Khatanga saddle is subdivided according to the probability of oil and gas bearing of different age deposits.

Keywords: oil and gas accumulation, catagenesis stage of organic matter, hydrogen index, petroleum prospects, Anabar-Khatanga saddle.

pdf  Secondary alteration of reservoir rocks of the Druzhny field (Western Siberia)
Grain contacts and pore mineral neoformations in the Jurassic and Cretaceous reservoirs of the Druzhny oil field indicate the intensity of epigenetic alterations. Studies of thin sections showed indications of two divergent types of epigenesis: progressive (catagenetic) and regressive (superimposed epigenetic). Vertical zoning of catagenetic and superimposed epigenetic alteration is identified.

Keywords: Jurassic deposits, Cretaceous deposits, producing horizons, pore space, resevoir, catagenesis, superimposed epigenetic processes, Druzhny field, Latitudinal Ob region, Western Siberia.

pdf  Geological and geochemical criteria of oil and gas bearing section in the contact zone of the Pre-Jurassic basement and sedimentary cover in the sublatitudinal Pre-Ob region
Numerous oil and gas fields, including the Rogozhnikovskoe large field and the Talinskoe giant field, have been discovered in Frolovsk and Priuralsk oil-and-gas bearing regions in Western Siberia. This area is covered with a dense network of wells reaching the Pre-Jurassic basement in the unconformity contact zone between the Pre-Jurassic basement and the sedimentary cover. The unconformity contact zone is poorly investigated by drilling within the territory of "Lukoil-Western Siberia" Ltd. activity in the sublatitudinal Pre-Ob Region. However, oil inflows enabling to rely upon the discovery of commercial pools have been obtained here as well. Assumed, reservoirs of hydrocarbons are as follows: crushing and fracture zones, weathering crusts of carbonate and effusive rocks belonging to the basement highs, sand-silt traps of the lower layers of the sedimentary cover. Geochemical data proved that oil source are predominantly clayey layers: Levinsk, Kiterbyutsk, Laydinsk, and Leontievsk Formations, overlapping the basement highs (or adjacent to them) in different areas in the region. Kitchen of the most intense hydrocarbon generation are confined to depressions of the 1st structural order. For the whole study area and especially for the most promising targets, distinguished by seismic, gravity, and geological-geochemical data were analyzed. The space genetic method as quantitative estimation of the initial hydrocarbon geological sources was used.

Key words: Western Siberia, sublatitudinal Pre-Ob Region, oil-and-gas content criteria, contact zone, oil and gas formation, quantitative assessment of resources.

pdf  Fluid-dynamic simulation in the sedimentary cover lower horizons of the Sredneob petroleum region, Western Siberia
The existence of fluid-dynamic systems in Jurassic and Cretaceous deposits of the Sredneob petroleum region central part, Western Siberia, is substantiated. For this propose the scale of oil and gas formation is assessed in the sedimentary cover lower horizons, the kitchens of intensive hydrocarbon generation and also the lateral and vertical transit zones and the zones of hydrocarbon accumulation are determined. Regional, zonal and local fluid-dynamic systems are identified. Based on the data on oil inflows, the distribution of disjunctive dislocations and the zones of pinching out of regional seals the forecast of distributing the high-output oil-saturated reservoir rocks in main productive horizons is performed.

Key words: Western Siberia, Sredneob oil-and-gas region, scale of oil-and-gas formation, fluid-dynamic systems, forecast of high-output reservoirs.
