Abstract
This article continues the cycle of scientific publications of “NK “Rosneft” PJSC devoted to the comprehensive study of the bazhen-abalaksky complex (BAC) on the territory of the Krasnoleninsky arch. The article presents the main results of complex laboratory core studies and substantiation of the principal model of reservoir structure in the unconventional fractured cavernous reservoir of the BAC, which served as the
basis for localization of potentially productive zones at the test site of one of the deposits of the Krasnoleninsky district.

Materials and methods
Materials: Complex laboratory studies were carried out on the core of 11 wells: lithological-mineralogical, sedimentological, biostratigraphic, geochemical, pyrolytic, geomechanical, mercury porometry and microtomographic studies, determination of filtration and capacitance properties. Methods: A mineral-component and petrophysical model of the
bazheno-abalak complex has been created.

Keywords
bazheno-abalak complex, a mineral-component model
