... and scanning electron microscopy it was discovered that the organic matter within gas shales contained significant porosity ( Loucks et al., 2009 , Moncrieff, 2009 ). Further work showed that the entire microstructure of gas shales is complex and heterogeneous ( Chalmers et al., 2009 ; Curtis et al., 2010...

...Palynofacies Methodology Conventional palynological processing technique was used to extract the organic matter (kerogen) from the samples. This included crushing about 10–15 grams of the sample in a mortar to the powder size. Samples were then treated with concentrated hydrochloric acid (HCl...

... of nanometers were found in organic matter; they occupy 40–50% of the kerogen body. Two-hundred two-dimensional SEM images were collected and stacked to reconstruct the original pore structure in a three-dimensional model. The model provided insights into the petrophysical properties of shale gas, including...

...Maturity Organic matter laid down at the time of deposition contains only traces of free petroleum hydrocarbons, far too little for even an organic-rich rock to act as a source rock without further change. Some changes, such as oxidation destroy some or all of the source potential...
