|Hydrocarbon investigation reserves targeting a Upper Devonian carbonate basin - Moroshkin area and contiguous zones (Timan-Peсhora petroleum Province)|
|A comprehensive interdisciplinary method for analyzing the geological structure and history of the sedimentary basin genesis, based on all available geological, geophysical and geochemical data and traditionally involving the analysis of stratigraphy (sequence-stratigraphic analysis) and sedimentology (sedimentological modeling), too has been used. A complete structural paleoprofile of carbonate sections of the Upper Devonian was constructed.
Taking into account the discrete nature of sedimentation, three sedimentary structures were distinguished with a characteristic sequence of beddings connected by the unity of time and place of studied formation, and a certain internal structure of parasequences composing them (tt-hw). Middle-Upper Frasnian and Famennian oil and gas bearing accumulations were identified. The distribution patterns of the thickness of productive levels and the values of the effective thicknesses of reservoir beds, as well as the distribution patterns of the values of the clay component coefficient in sections of these structures, are constructed. The exploration forecast of hydrocarbon traps in their productive part is made.
Keywords: Upper Devonian sedimentary basin, sequence-stratigraphic analysis, sedimentary structures, parasequence (tt-hw), Middle-Upper Frasnian and Famennian oil and gas accumulations, hydrocarbon traps, Timan-Pechora petroleum Province.
