Abstract: Gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) methods are used to analyze crude oils obtained from Mil Qasim (MQ-1) and Sarqala (S-1) oilfields of south-eastern part of Iraqi Kurdistan using different biomarkers coefficients. Biomarkers characterization are used to provide information on the source of the organic matter, depositional environment, degree of maturity, age determination of the crude oils and their correlation between each other. The used data include normal alkanes and acyclic isoprenoids distributions, terpans, hopanes, steranes and diasternes aliphatic biomarkers, the distribution of aromatic biomarkers naphthalenes, dibenzothiophene, phenanthrene, methyldibenzothiophenes and stable carbon isotope. The oil samples from Mil Qasim and Sarqala oilfields are characterized by a low Pr/Ph ratio (< 1,0), a relatively low oleanane ratio, abundance of moderate C₂₇ regular steranes and diasteranes, a relatively high C₃₀ sterane index, the presence of tricyclic terpenes, relatively high dibenzothiophene / phenanthrene ratios, high CPI ratio (≥ 1,0) and high Ph/nC₁₈ ratio. All of the above parameters indicate that the source rocks represented by calcareous marls were deposited under anoxic — reducing marine environments with type II of organic matter and were generated at moderate stage of maturity. All of the age diagnosed biomarker parameters indicate that the source of oils in Mil Qasim and Sarqala oilfield are the Lower Cretaceous formations (Balambo-Qamchuqa formations). Two samples of oil from the Mil Qasim field (MQ-1) and oil samples from the Sarkal field (S-1) show an excellent oil-oil correlation based on the comparison of biomarker characteristics.<

Abstract: Currently, there are many promising objects for the search for accumulations of hydrocarbons (HC). In many drilled oil and gas fields, intense oil and gas occurrences, evidence of possible accumulations of oil and gas are noted. Despite a rather wide regional geological exploration and development of hydrocarbon resources, poorly studied structures characterized by the development of folded-thrust dislocations are promising from oil and gas perspective.
The use of kinematic modeling technology allows to restore the history of the geological development of the region, to study the features of the formation of the modern morphostructure of the sedimentary cover, and also to assess the balance of structural plans and the direction of tectonic movements over the area and in time, as well as to typify discontinuous disturbances and determine the time of their formation.
The article presents the results of a detailed study of the features of the tectonic structure and geodynamic evolution of the sedimentary basin of the Ural fold system, as well as the mechanisms of formation of reverse-thrust structures based on structural-kinematic modeling. The conditions for the formation of hydrocarbon traps associated with dislocational thrust type dislocations are determined, faults are typified within the junction zone of the Ural marginal trough and the Ural folds based on the analysis of paleotectonic reconstructions.
