Abstract: Chengbei sag is one of the structure units of the Bohai Bay basin, which is a major oil and gas field in China. It is a graben basin depositing on the basement of Precambrian and mainly developing Cenozoic sedimentation. The hydrocarbon potential and saturation of these deposits are considered

Abstract: The geochemical studies were performed for the core samples of Shiranish formation in the depth interval of (3680-3950) from the south-eastern part of Iraqi Kurdistan. These rock samples comprise shale rocks. The geochemical investigation of biomarker parameters were performed for extract rock samples from Shiranish formation using gas chromatography GC, gas chromatography-mass spectrometry GC/MS — for saturated and aromatic hydrocarbons, and GC/MS/ MS — for saturated hydrocarbon. In addition, performed carbon isotope analysis of saturated and aromatic fractions. The extract samples are characterized by a high Pr/Ph ratio (> 1,0), a relatively high oleanine ratio, an abundance of mode- rate C₂₇ regular steranes and disteranes, a relatively high C₃₀ sterane index, presence of tricyclic terpanes, relatively low dibenzothiophene/phenanthrene ratios, a high CPI ratio (³ 1,0) and high Pr/n-C₁₇ values in combination with low Ph/n-C₁₈ values.
All of the above parameters indicate on the mixed type of organic matter: kerogen type II + III with a predominance of type II. According to the results of diagnostics, Source rock, represented by calcareous marls, were deposited under weak reducing conditions during diagenesis and have a high degree of maturity.

Abstract: The article describes outstanding difficulties of Arctic shelf development requiring underwater floating platforms introduction. Authors compare mooring positioning for newly proposed underwater platform with the conventional semi-submersible rig. Based on calculation results a conclusion is made regarding significantly lower environmental loads on underwater platforms and consequent reasonability of application of such units for Arctic shelf development

Abstract: The results of laboratory measuring of gas-dynamic parameters in the fracture during evaporation of its walls are presented. The fracture of a shale layer was simulated by a slit created in plexiglass. The fracture was blown through by gas flow, its speed was experimentally measured. The values of flow rates, evaporation speed and entrainment of the mass of material from the surface of the slit are recorded. The shall recovery factor is calculated under laboratory conditions
