Abstract
During the last recent years VI. Shpilman research and analytical Centre for the rational use of the subsoil carries out detailed studying of the Upper Jurassic Bazhenov Shale that is considered to contain the largest amounts of shale oil resource in the world. The sizable database of geologic information from the whole territory of Khanty-Mansiysk Autonomous Okrug-Ugra, which contains geochemical and lithologic analyses of core samples (from more than 300 wells), data of well tests, logs, seismic information and etc., allows to map various characteristics and construct a model of the Bazhenov shale.
The proved oil presence in the Bazhenov shale (spreading of discovered deposits, oil production rates) is compared with various lithological, mineralogical, geochemical and thermobaric factors. The critical parameters and their values were substantiated: reservoir temperature of the Bazhenov shale, specific hydrocarbon generation and maturation level of kerogen. The map of regional prospects of the Bazhenov shale was predicted by superposition the distributions of abovenamed parameters with taking into account spreading of the “Abnormal Bazhen” zones and hydrocarbon generation area boundaries. Five categories of lands of various degree of prospects are marked out.
