The paper presents Tatyana V. Maydl’s researches of formation and patterns of distribution of natural reservoirs in carbonate deposits of the Timan-Pechora oil and gas province. Tatyana Viktorovna Maydl is a recognized specialist in oil and gas geology. Her significant contribution to the development of the theoretical base of formation of carbonate deposits in the region, reconstruction of sedimentation conditions, finding degree of influence of secondary transformations on the reservoir and filtration properties of carbonate rocks, development of the basis for geological models of carbonate reservoirs, are analyzed. In the field of studying the morphology of the void space in low-capacity carbonate reservoirs, T. V. Maydl found that in the Lower Silurian dolomites with a shadow biohermal structure had the best filtration features, and in the Upper Silurian — bioclastic limestones. The main volume of the void space in the first type is associated with caverns and cracks, in the second — with matrix porosity. We showed that the results of T. V. Maydl’s work were not only of theoretical, but also of practical importance.
