“…It aims to measure and calculate horizontal extension amounts resulted from extensional process on seismic sections perpendicular to extensional structures. The present seismic section is restored by rock deformation and stratigraphic extensional deformation by using balanced cross‐ section technique to obtain horizontal extension amounts in sedimentary basins (Al‐Matary & Ahmed, 2012; Berra & Carminati, 2010; Dahlstrom, 1969; Gibbs, 1983; Schonborn, 1999). The specific workflows are designed based on schematic diagram (Figure 4).…”

Based on seismic interpretation of 18 regional 3D high‐resolution seismic sections across Liaodong Bay, extension amounts, extension rates and extension coefficients of different seismic sections from the south to the north are calculated by employing balanced section technique. Then, spatio‐temporal distribution of extension amounts is characterized and interpreted. Finally, the analysis of genetic mechanism is conducted and analysed. The results indicate that tectonic evolution in the Paleogene of Liaodong Bay is characterized by episodic extension. Furthermore, spatio‐temporal distribution of extension amounts is relatively uneven. In terms of space, extension amounts are mainly caused by extensional displacement of main depression‐controlled boundary faults and syn‐depositional faults in the depression. In addition, extensional amounts along main depression‐controlled boundary faults are characterized by larger displacement. In terms of time, the periods for horizontal extensional movement can be divided into three stages: The Palaeocene‐Early Eocene (Kongdian Formation‐third member of Shahejie Formation), Middle‐Late Eocene‐Early Oligocene (first and second member of Shahejie Formation) and Middle‐Late Oligocene (Dongying Formation). Among them, extension during the Palaeocene‐Early Eocene occurs both in the north and south of Liaodong Bay. However, extension intensity in the north is stronger than that in the south. Extension intensity in the middle and north during Middle‐Late Eocene‐Early Oligocene obviously increases. In contrast, it is dominated by strike‐slip movement during depositional period of Dongying Formation. Therefore, extension intensity is characterized by significant inheritance. Spatial–temporal distribution of extension amounts is predominantly controlled by tectonic evolution and associated tectonic deformation.

“…In the last decades, many researchers dealt with evaluating the oil-bearing reservoirs in the Masila Basin and characterizing its source rock potentiality through analyzing the available petrophysical, geological, well logging, and geochemical data. − Several published studies believed that the Upper Jurassic shale sediments of the Madbi formation are the high-quality source rocks for oil in the Masila Basin. , Although the majority of earlier studies suggested that the organic-rich shale interval of the Madbi formation is conventional petroleum source rock in the northern Masila Basin, more analyses are still needed in the whole Masila Basin, more specifically to the molecular structure of the oil-asphaltene, to investigate the sources of oil accumulations and their related source rocks. In this regard, the current study attempts to investigate the compositions and characteristics of the oil-bearing sandstone samples from the Lower Cretaceous sandstone sequence in the Kharir-2 exploration well, Kharir oilfields (Figure ) using organic geochemical data sets, along with a molecular structure of the oil-asphaltene, and provide more information about the whole properties of their probable source rock.…”

Oil-bearing sandstone samples were collected from the Lower Cretaceous sequence in the Kharir-2 exploration well, Kharir oilfields (Eastern Yemen). The current study integrates biomarker of the aliphatic hydrocarbon fraction of the extracted oil with a new finding from the molecular structure of the oilasphaltene, in order to learn more about their properties, including organic matter (OM) input, depositional environment, and thermal maturity. The overall oil composition results show that the extracted oils have a high saturated hydrocarbon of up to 50% and significant levels of aromatic hydrocarbon and polar components, indicating generally paraffinic to naphthenic oil. This claim agrees with the molecular structure of the kerogen derived from the pyrolysis−gas chromatography result of the oilasphaltene, which suggests that the extracted oils from the Lower Cretaceous sandstone reservoirs are mainly paraffinic-naphthenicaromatic oils, exhibiting low wax content and originated from marine type II kerogen. The type II kerogen of the marine-source rock is also demonstrated by the bulk kinetic model of the oil-asphaltene for the extracted oils, with a broad range of E a between 38 and 62 kcal/mol and a frequency factor (A) of 1.52−1.47 × 10 13 /1 s. The biomarker characteristics of the aliphatic fraction show that the extracted oils from the Lower Cretaceous sandstone reservoirs were generated from clay-rich source rock, containing OM origin of mainly marine and terrestrial OM input and deposited under suboxic environmental conditions. Furthermore, the maturity-sensitive aliphatic biomarker parameters indicate that the extracted oils were generated from mature source rock in the range of the peakmature stage of the oil generation window. Oil−source rock correlation of various established biomarker proxies for OM origin, depositional environment, and lithology suggests that these extracted oils were possibly generated from a single source rock, and the Madbi clay-rich formation contributed to most of the extracted oil from the Lower Cretaceous sandstone reservoir rocks.
