Methane adsorption capacity is an important parameter for coalbed methane (CBM) exploitation and development. Traditional examination methods are mostly time-consuming could not detect the dynamic processes of adsorption. In this study, a modified low-field nuclear magnetic resonance (NMR) method that compensates these shortcomings was used to quantitatively examine seven medium-rank coals. Bas...

Abstract Knowledge of the tectonic history Pamir contributes to our understanding both evolution collisional orogenic belts as well factors controlling Central Asian aridification. It is, however, not easy decipher Mesozoic–Cenozoic tectonics due extensive Neogene deformation in an orogen that remains largely understudied. This study reports detrital apatite and zircon fission‐track (FT) ages f...

A significant portion of planned energy and mineral resource investment into Australia is now for hydrogen (H2). Whether from fossil fuels with carbon capture storage or electrolysis water using renewable energy, there a price premium manufactured hydrogen. The production H2 geological sources (geologic H2) could be more cost-effective. majority geologic are abiotic their potential largely unkn...

To the accurate reconstruction of hydrocarbon generation history in Dongying Depression, Bohai Bay Basin, East China, core samples Eocene Shahejie Formation from 3 shale oil boreholes were analyzed using organic petrology and geochemistry methods. The shales are enriched matter with good to excellent potential. maturity indicated by measured vitrinite reflectance (%Ro) falls range 0.5–0.9% incr...

Raman spectroscopy on carbonaceous material has become the most used geothermometer in Earth science studies. However, its application very different settings, associated with heating rates, demands an updated review to understand paths of maturation that can occur geological record. A comparison between organic matter matured under slow (diagenesis and regional metamorphism) or fast (around sh...

This work investigates bituminite (amorphous sedimentary organic matter) in Upper Jurassic Kimmeridge Clay source rock via confocal laser scanning microscopy (CLSM) and atomic force (AFM). These petrographic tools were used to provide better understanding of the nature bituminite, which has been historically difficult identify differentiate from similar matter types rocks. As part an Internatio...

Depositional environment and source potential of the different organic-rich levels of Devonian age (up to 990m thick) from the onshore EC-1 well (Southern Tunisia) were investigated based on the analysis of more than 130 cutting samples by different geochemical techniques (Rock-Eval pyrolysis, GC-MS). The obtained results including Rock Eval Pyrolysis data and biomarker distribution (terpanes, ...

The present study focuses on source rock evaluation of the Sargelu Formation by using core chips rocks collected from well Atrush-2, Duhok, Kurdistan Region-Iraq. Rock-Eval pyrolysis and vitrinite reflectance were executed. Subsequently, selected parameters used for 1-D Basin Modelling calibration. upper part formation mainly comprises argillaceous limestone with low content organic matter (0.6...
