... Abstract Shale gas is considered as an unconventional source as the gas is derived from adsorbed gas in organic matter. Methane in shales is generated from the transformation of organic material by bacterial and geo-chemical processes. The gas so generated gets stored by multiple mechanisms...

... Abstract: The organic matter contained in sediments is an excellent maximum palaeothermometer. Temperature- time factor modifies the optical properties of the organic matter and increasing diagenesis results in an increase in reflectance. Observation of recent temperatures reveal that great...

...- Early Eocene). Various geochemical and geooptical techniques were used for characterization and evaluation of source rocks for petroleum by determining the amount of organic matter, the type and nature of organic matter and thermal maturation of organic matter found in the argillaceous sediments...

... and Ordovician, the sandstones of lower Devonian (Emsian) and of Tournaisian- Strunian. All the horizons likely to form source-rocks were sampled and analysed. The northern flank of the basin shows a higher organic matter ratio with the following values: - The Ordovician, of about 2000 m thick, holds clay...

... petrographic studies and elemental analysis of Kerogen indicate that the organic matter are mainly type III with minor amount of type II. Variation in sandston to shale ratio and vitrinite reflectance study show that Kitchen area lies on the NE of the area and organic matter are at the catagenetic stage...
