... tests on these samples included pyrolysis, TOC, X-ray diffraction (XRD), Dean-Stark extraction, helium porosity, and DRA. The DRA method included argon-ion milling, SEM imaging, image processing, and quantitative image analysis. Rock properties determined from physical tests were water saturation (Sw...

... and divided into 24 intervals (approximately 1.25 mm each). Samples were taken from each interval on the slab for SEM, FTIR, SRA, crushed helium porosity, and TOC measurement. As indicated, the samples were taken such that the material for each test was taken as close as possible, horizontally, to other test...
