“…6: TOC vs. S2 for the studied samples [58].. TOC also used vs total sulfur content to illustrate the environment of deposition (Fig. 7), which revealed that the OM deposited mostly in non-marine environment [55] under oxic to suboxic conditions [56]. It is appears that organic sulfur (Table 5) is generally less than the total sulfur (Table 1) content of the studied samples.…”

The investigation of new energy sources become one of the world tasks in the last decades. Oil shale is one of the promising energy sources and widespread in many parts of Egypt. So, this work was conducted to investigate hydrocarbon potentiality, geochemistry and environmental impact of Magharet El Maiah Formation black shale, Southwest Sinai. This shale is of Carboniferous age and composed mainly of kaolinite, montmorillonite and illite in a decreasing order with quartz and pyrite as non-clay minerals. They are deposited under oxic non-marine condition. Chemical analysis revealed that paleo-redox elements for the studied area were deposited under oxic environment and subjected to highly intensive chemical weathering. The calculated pollution indices indicated the mostly studied black shale isn't polluted. However, the studied black shale is enriched with some economic trace elements than the UCC and PAAS, especially Pb. All the studied samples are of indigenous origin. The organic richness of the studied samples ranges from fair to excellent total organic carbon content. The kerogen type is IV; the organic matter reaches the overmature stage and can be generate dry gas.

“…Although black shales in Peninsular Malaysia cover 25% of the total surface area, exploration for commercial shale gas was almost nil in the onshore Peninsular Malaysia. Black shales on Peninsular Malaysia have been characterised to a range of immature, matured and overmatured source rocks employing source rock characterisation parameters such as TOC, rock-eval pyrolysis and the vitrinite reflectance analyses [1][2][3]. Such variations in these parameters could result from various factors such as the impact of mineralogy, tectonic evolution and burial history of black shales in the Peninsular.…”

Even though the black shales in Peninsular Malaysia covered a quarter of the total surface area and have been overlooked for their economic potential except few workers have evaluated their thermal maturity using rock-eval pyrolysis, vitrinite reflectance analysis and illite crystallinity. According to these research works, the shales have been categorized into immature, mature and overmatured successions, which in turn dictated the exploration activities of commercially viable shale gas in the onshore Peninsular Malaysia. In this work, published and unpublished data on the scattered black shales of Peninsular Malaysia were examined to assess exploration potential of shales from various stratigraphic windows. Thus, using comparative evaluation of all the thermal history plots of the black shales from Peninsular Malaysia; areas of thermally matured source rocks are identified. According to the thermal maturation assessment; the Palaeozoic black shales in the Peninsular Malaysia have minimal generative potential for economically viable source rock for hydrocarbon, whereas the younger successions of Oligocene to Miocene have considerable potential to serve as source rocks of feasible prospect, provided permissible geological settings are met.

“…With their continuous exploration and development, shale gas reservoirs have been the subject of increasing attention (Dong et al, 2016;He et al, 2017;Kim et al, 2019;Owusu et al, 2019), particularly as they currently represent fields of new reserves, especially for countries such as China that already host large conventional reservoirs. Accordingly, many countries, including China, the United States, Mexico, Argentina, South Africa, Australia, Canada, Poland, and France, have begun to explore and develop shale gas reservoirs (Yin et al, 2016;Morga and Kamińska, 2018;Jiang et al, 2019a), and hence, research on shale gas reservoirs is incredibly extensive.…”
