The reasoning of prospects of oil and gas bearing capacity of Cretaceous deposits of the Outer zone of Carpathian foredeep

Abstract

Although the Outer zone of the Precarpathian foredeep is one of the oldest gas extraction regions of Ukraine it is still promising for the exploration of new oil and gas deposits. The main gas deposits are open here in the Miocene, but the number of unidentified structures is rapidly shrinking. The development of unexplored Cretaceous deposits and the possibility of opening up their deposits of oil and gas can provide an increase in the resource base. In this case, the importance of the prospects of oil and gas bearing capacity of Cretaceous deposits is determined by a set of criterion features, including the determination of the nature of collectors and caprocks distribution, the establishment of favorable hydrogeological, structural and tectonic conditions for the formation and conservation of oil and gas deposits. The substantiated oil and gas prospect increases the search engine success, and therefore the development of the hydrocarbon potential of the Cretaceous deposits of the Outer zone can make a significant contribution to the fuel and energy supply of Ukraine with its own raw materials. Generalization, systematization, and analysis of new and reinterpretation of previously performed geological and geophysical studies and the results of deep drilling made it possible to substantiate the reliable geological structure of the cretaceous deposits of the studied region, which will increase the efficiency of prediction of oil-and-gas saturation and determine the priority oil and gas prospecting objects for detailed geological and geophysical works in order to search for new oil and gas deposits. Research results will increase the efficiency of search work, and the growth of promising and projected resources will be a significant contribution to the task of stabilizing and increasing oil and gas production in Ukraine.
