To evaluate the reservoir characteristics of siliceous shale in Dalong Formation within late Permian intra-platform rift trough Western Hubei (China), we studied a drill core from well ED-2 Hubei. analyze physical characteristics, pore structure, methane adsorption performance, and their influences on reservoir, performed X-ray diffraction, total organic carbon (TOC) content, vitrinite reflecta...

Shale oil has become a global hotspot of unconventional exploration and development. In this study, the latest drill core experiment analyses Qingshankou Formation in northern Songliao Basin were used to evaluate its lithofacies classification, sedimentary environment, pore types, pore-throat structure characterization, shale potential. Lithofacies classification was determined according total ...

An assessment performed using raman spectroscopy has found space in the black shales of Cisuralian-age rocks Karoo Basin South Africa, particularly those from Guadalupian Ripon, Cisuralian Whitehill and Prince Albert Formations. It is used conjunction with geochemical screening techniques such as organic petrology programmed pyrolysis. In turn, combination these for thermal maturity sedimentary...

The Carboniferous–Palaeogene Wandel Sea Basin of eastern North Greenland (north 80°N, east 40°W) is an important piece in the puzzle Arctic geology. It particularly for understanding how Paleocene–Eocene convergence between Greenland, Canadian and Svalbard relates to compressional tectonics High Arctic, collectively known as Eurekan Orogeny. In this study, we present apatite fission-track analy...

The Cenomanian-Turonian Eagle Ford Formation is a widespread organic-rich mudrock in Texas and northern Mexico. economic significance of this unit for oil gas production USA has led to numerous investigations documenting its lithological geochemical variability. Comparatively little known about facies distribution source rock potential Here, we studied section the central part Sabinas basin. In...

Rock pyrolysis, organic petrology, vitrinite reflectance, gas chromatography-mass spectrometry (GC-MS) analysis, and biomarker compound analysis were performed to comprehensively analyze the geochemical characteristics of Jurassic Da’anzhai Member (J 1 da) shale strata in Yuanba Puguang areas northeastern Sichuan Basin. Then matter provenance sedimentary environment further analyzed. Finally, s...

Lithium isotopes (δ7Li) in coals have been shown to increase with thermal maturity, suggesting preferential release of 6Li from kerogen porefluids. This has important implications for paleoclimate studies based on δ7Li buried marine carbonates, which may incorporate Li porefluids during recrystallization. Here, the content and isotopic composition macerals two coal seams intruded by dikes, were...

The Middle to Late Eocene Mangahewa Formation in the Taranaki Basin has been evaluated for its petroleum system (source potential and reservoir qualities). is generally interpreted as an alternating marginal shallow marine environment, with lithologies consisting of sandstone, siltstone, mudstone bitumonius coal. pyrolysis results show very good source rock generative total organic carbon conte...

Daerah penelitian berada pada Desa Tanjung Belit, Kabupaten Dharmasraya, Sumatera Barat yang termasuk dalam Cekungan Selatan, Sub-Cekungan Jambi. Metode berupa pemetaan dan pengambilan conto sampel batubara dilakukan sebagai dasar analisa maseral piroksimat. Berdasarkan dari hasil analisis maseral, daerah dapat dibedakan menjadi dua seam batubara, yaitu Seam A B. Hasil RV (Refletan Vitrinite), ...
