Summary: The geochemical characterization of organic matter in the Devonian Pimenteiras Formation in the Parnaiba Basin, Brazil, indicates a potential for hydrocarbon generation, mainly natural gas. High S-1 and S-2 values, along with low Tmax values, suggest very good to excellent source rock potential. The mineral assemblage, vitrinite reflectance, and palynological records also support the potential for hydrocarbon generation in the Pimenteiras Formation.

Summary: Through the application of organic petrography, palynofacies, and geochemistry, the origin, nature, and character of lignite deposits in the Sonari mine of Barmer Basin, Rajasthan were investigated. The results provide insights into the thermal maturation and hydrocarbon generation potentiality of these lignite-bearing deposits.

Summary: The article describes the lake types and sediment characteristics of the Aptian Codo Formation in the Parnaiba Basin, Brazil. Through multiple methods of analysis, it is shown that the lower portion of the Codo Formation deposited five stages of sedimentation, including expanded lake, brackish ephemeral lake, perennial shallow lake, evaporitic sabkha, and stratified lake. These stages were influenced by the relationship between inflow and evaporation rate, which in turn affected the sediment properties and formation processes of the lakes.

Summary: This study investigates the Upper Devonian Antrim Shale Formation in the Michigan Basin, providing insights into biostratigraphy, paleoenvironment, sea level fluctuations, organic matter properties, and source rock potential. The research reveals high organic matter content and excellent hydrocarbon generating potential in the Norwood, Lachine, and Upper members, while the Paxton Member has poor to fair organic richness and low hydrocarbon potential.

Summary: The study shows that Permian-Carboniferous sediments in the NAFB contain abundant organic matter, with coals having a potential for gas accumulation and bituminous shales being potential source rocks for oil. This is important for understanding the hydrocarbon potential and depositional environment of coal and bituminous shales.

Summary: Samples from the Devonian succession in the Sifa-1X well were examined to study the distribution of liptinite macerals and to assess paleoclimatological and paleoenvironmental changes during sedimentation. The findings revealed two phases of basinal dynamics and the impact of oxygen levels on the preservation of organic matter, particularly liptinite macerals. The organic matter in the Devonian strata was found to have the potential to generate oil and gas.

Summary: The petrophysical properties of the Abu Madi reservoir in the northern Nile Delta Basin were evaluated based on well logging data from two wells, showing promising gas zones in both wells at similar depth intervals. The observed depth variation was attributed to the presence of buried normal faults between the wells.

Summary: Chemical analysis data was used to study the properties of liquid fluids in the oil-bearing system of the Wuliyasitai southern sag in the Erlian Basin. The stable carbon isotope (δC-13) values of hydrocarbons indicated a biased lacustrine algal input. Gas chromatography-mass spectrometry was employed to examine the morphological characteristics of various organic compounds. The research findings suggest that water washing, crystallization, and wax precipitation are common occurrences in oil samples, and the salinity of formation water and the abundance of characteristic biomarkers can provide insights into the ancient water body's salinity as well as the hydrocarbon storage environment.

Summary: Lacustrine mudrocks, with their high organic matter content, are important hydrocarbon source rocks. This study focused on the lacustrine mudrocks of the Eocene Shahejie Formation in the Dongying Sag of China to determine the origins of the organic matter and evaluate the hydrocarbon generation capacity. By improving the classical palynofacies classification scheme, the researchers accurately reflected different lacustrine environments. The different palynofacies types exhibited different hydrocarbon generation abilities, leading to distinct hydrocarbon potential in different formations of the Dongying Sag.

Summary: The Lower Cretaceous Chijinbao Formation in the Jiuxi Basin of Northwest China is a primary source rock that has been poorly studied due to incomplete stratigraphic sequences. Through integrated analysis, this research identified the distribution of source rocks, organic matter sources, and depositional environments. The sequence exhibits varying characteristics of lithology and hydrocarbon potential in different parts.

Summary: Samples of Albian Te acute accent gulines Clay near Brienne-le-Château in the Paris Basin were analyzed for their geochemical characteristics of organic matter. The study revealed low Total Organic Carbon contents, immature organic matter, and preservation of gel-like amorphous OM in anoxic environments. The oxidation of natural organic matter in the reduced marine clay formation was found to be minimal in the presence of oxygen.

Summary: Palynofacies analyses of cutting samples from the ST 9H well in the Tano Basin revealed four palynofacies units representing different marine environments. The recovered dinoflagellate and miospore assemblages suggest a Campanian-Maastrichtian age and a warm and humid tropical-subtropical climate.

Summary: This study on source rock samples from the upper shale unit in the Lower Goru Formation of the Lower Indus Basin found that the samples have fair source rock potential and may be considered as a good candidate for hydrocarbon generation perspective. The study also revealed that the organic matter in the samples is mainly terrestrial and the depositional conditions vary from anoxic to dysoxic. Various maturity parameters showed mature organic matter input and peak oil-window for the samples, indicating an increase in thermal maturity with depth.
