Etude de la production et de la migration des hydrocarbures dans le bassin du Donets en Ukraine : Aspects économiques et Exploitation

Abstract : The objective of this thesis is to study the capacity of two different humic coals to generate hydrocarbons.Two bituminous humic coals were selected for this study in objective to evaluate their petroleum potentiality, a Cretaceous coal from the basin of Sabinas, and two Carboniferous coals from the basin of Donets. Pyrolysis in confined system was used in this work. More oil, wet gas, solid bitumen and even methane were produced during the pyrolysis of Donets coals than its amount produced from Olmos coal.The obtained results of modeling study of the petroleum system in Donets Basin show that: coalification level increases towards the E & SE parts of studied area of Donbas, the major erosion phase occurred at late Permian time with maximum total erosion in the SE part, the main phase of hydrocarbon generation occurred during the Carboniferous and early Permian subsidence phase, three phases of oil expulsion from source rock in Donets Basin were predicted, the major quantity of trapped methane is located in the southern and northern parts of main anticline.Finally, in this work a simple experimental relation between the generation of methane and %Rr of coal was formalized and validated by using field data and the results of the modeling study in the basin.
