TL;DR: In this article, dry samples of torbanite and soft brown coal have been artificially matured in an attempt to simulate conditions in a subsiding sedimentary basin with a constant geothermal gradient.

TL;DR: The role of coal in the generation and migration of hydrocarbons is discussed from the viewpoints of chemistry and petrology in this paper, where it is shown that under geochemical conditions most coal can give rise to oil, as well as gas.

TL;DR: In this paper, the effect of a small igneous intrusion on Rundle oil shale was evaluated using a range of techniques, including X-ray diffraction, thermal and isotopic analyses, gas chromatography-mass spectrometry, electron spin resonance, nuclear magnetic resonance spectroscopy and demineralizing techniques.

TL;DR: The hydrocarbon secreting alga Botryococcus has been identified in organic remains of sediments ranging from Precambrian to Recent, and is believed to have been a major source material for petroleum generation throughout the geological time as discussed by the authors.

TL;DR: In this paper, an approximate relation based on atomic ratios is derived for slow geological heating but is also valuable for comparing samples under other conditions, and the percentage of oil, on a weight basis, that can be generated is given by: Oil = 66.7 H C − 57.0 O C −33.3.
