TL;DR: In this article, the pore structure characteristics of the Lower and Upper Permian shales belonging to the Barren Measures and Raniganj Formations, respectively, were investigated using the low-pressure N2 adsorption-desorption experiments.

TL;DR: In this paper, the authors have selected sixty six borehole shale samples of different formations from different parts of Raniganj basin, West Bengal, India, for the purpose of shale gas assessment, and carried out rock eval pyrolysis and total organic carbon analysis and petrographic characterization of the shales were carried out.

TL;DR: For the purpose of assessing methane sorption capacity, degree of conversion of organic matter and hydrocarbon prospectivity, twenty one borehole shale samples of the Lower Permian Barakar Formation were studied from the West Bokaro and Raniganj basins in India as discussed by the authors.

TL;DR: In this paper, the authors used low pressure N2 adsorption-desorption isotherms to categorise pore geometry such as cylindrical, slit-shaped and bottle neck pores in Raniganj, Barren Measures and Barakar shales respectively.

TL;DR: In this article, the significance of fractal dimension, pore dispositions and associated geological influence on pore structure and fractal dimensions for better understanding of gas adsorption capacities of coal seams of East Bokaro.
