Mesozoic system of DDD: perspectives, exploration and oil and gas bearing estimation methods

Abstract

Oil and gas perspective Mesozoic complex in Dnieper-Donets depression includes Triassic, Jurassic and Lower part of Cretaceous systems. Its common thickness can reach one kilometer and much more. The deposit complex widely spread in Preaxial and Northern near-edge zones of Depression. Geologic and log data about potential Triassic and Jurassic rocks hydrocarbons bearing on several of tens local structures, not including here already known Mesozoic fields, there exist missed productive layers and even stratigraphic complexes, point on exclusive interesting character of this exploration direction. The fact is strange and hardly explainable, but since 1960s years systematic study of Mesozoic rocks in Eastern Ukraine has not been executed. Meanwhile, there are no theoretic foundations which contradict to possibility of Mesozoic commercial hydrocarbon pools forming on most part of Eastern Ukrainian oil and gas bearing basin territory, on the contrary, most of its uplifts have favourable genetic, migrational and accumulative terms of Triassic, Jurassic, and probably Cretaceous hydrocarbon pools existence. Triassic and Jurassic systems deposits of DDD characterized by small and middle bedding depth, freandly thermic, pressure and hydrogeochemical environment. Perspective folds and uplifts mostly sityated in areas with convenient search and development infrastructure. Rational searching complex of works, directed on Mesozoic pools discovery and commercial exploitation proposed.
