pdf  On the influence of catagenetic variations of the Lower-Middle Jurassic deposits of the West Siberian sedimentary basin on their petroleum potential
The influence of catagenetic processes of the Lower-Middle Jurassic deposits transformations on hydrocarbon phase state variations is considered based on vertical catagenetic zonation of rocks studied from more than 300 deep exploratory and stratigraphic well sections, on oil and gas-condensate composition considering quantitative indexes of material composition and rock transformation level. The results obtained may be taken into account in the forecast of hydrocarbon phase state variations, enhanced reservoirs, quality of oil in areas poorly explored by drilling.
Key words: catagenetic zonation, terrigenous rocks, petroleum potential, oil composition, improved reservoir, Lower-Middle Jurassic, West Siberia.

pdf  The impact of faulting on thermal regime and catagenetic transformations of Mesozoic deposits, West Siberian plate

The results of thermal field study in the Mesozoic sedimentary cover of the West Siberian plate are provided, the patterns of the thermal field vertically and laterally transformation are presented. The essential role of the deep faults penetrating from the basement into the sedimentary cover in the formation of the temperature and catagenetic anomalies has been proved. It is shown that anomalies in the thermal field can serve as indicators of fluid-conducting deep faults and their distribution scope. The maps of the catagenetic anomalies distribution for each level of the Lower and Middle Jurassic sand sedimentation are made up on the basis of the organic matter catagenesis maps and the maps of disjunctive tectonics of the West Siberian plate. The relationship between most anomalies and rift gutter areas, deep faults and their cross-intersections has been established. The data obtained may be taken into account in the forecast of oil and gas accumulation zones in the Mesozoic sediments of West Siberian plate.
Key words: West Siberian plate, Mesozoic sediments, deep faults, rift gutters, thermal field, thermal anomalies, catagenetic anomalies, fluid-migration processes
