The article considers the wells that have penetrated the carbonate sediments with the geological and paleontological information. By the late Devonian epoch paleogeographic scheme they are located in certain megazones with their inherent characteristics of sedimentation. Examples of lateral relations of carbonate or shalecarbonate rocks with subordinate volcanic rocks on Lovinsky and Khanty-Mansi areas are given. A variety of types of carbonate rocks is associated with structural features of basins in which there was sedimentation, as well as various secondary processes. Based on new geological information, obtained in recent years on Galyanovsk, South Galyanovsk, Khanty-Mansi and other areas, the areas of distribution of carbonate deposits within the Frolovskaya megadepression are clarified. Their petroleum potential is associated with reef structures is mostly confined to near rim parts of the deep depressions of the basement, a reliable mapping of which is possible with more detailed geophysical work.
