Peculiarities of The Structure of Productive Layers and Perspective Zone Localization of Unconventional Reservoir on The Example of a West Siberian Oilfield

The area of research was delineated at the 400-km2 Em-Egovsky license block. Research work was attempted at this block for the purpose of developing the hydrocarbon reserves localization technology in Bazhen-Abalak complex (BAC). As a result, 14 petrotypes (reservoir and non-reservoir) were identified, 5 fracture zones were singled out and algorithms of volumetric parameters and brittleness for BAC were obtained. On the basis of detailed 3D geological model of double porosity methodological algorithms for productive zones localization were proposed using key parameters. Regions of experimental-industrial drilling with first ordered wells were proposed for confirmation and exploration of high-potential zones.
