Study and investigations of oil and gas reservoirs in Lower Cretaceous (K1) in Amu-Darya basin, Afghanistan

The importance of this research paper is about the structure and the condition of oil and gas formation in the Lower Cretaceous complexes (K1) in the northern part of Afghanistan in order to determine the depth of the reservoir rocks, to evaluate the formation of the oil and gas reservoirs and to provide clear suggestions in terms of economic possibilities for better performance of exploration and exploitation works in the study area. With increasing the number of muddy sediments, the amount of organic materials is increased in the depressed parts of the study area in the cross-section of the Neocom complex. Therefore, the Neocom complex rocks are the mother rocks of oil and gas. It seems that in the areas where the Upper Jurassic evaporitecaprocks are less developed and the faults and fractures are more, it is possible that the hydrocarbons may migrate from Jurassic to the Lower Cretaceous sediments, including Neocom. The XIV (Hauterivian), XIII (lower part of Barium), and XII (Aptian Suite) and XIa (sub-Suite of the lower Albian) formations are the collector rocks of this natural reservoir.
