ABSTRACT The primary objective of this study is to demonstrate the correlation between bitumen presence identified using Pyrolysis analysis in core/cuttings, and petrophysical data from NMR logs in the Jurassic Marrat Formation, Kuwait. Since the presence of bitumen in the reservoir presents...

... formations, heat-treated at 650°C (high thermal maturity), become oil-wet. The results suggest that kerogen is hydrocarbon-wet at high thermal maturity and remains water-wet at low thermal maturity. We also recorded the contact angle in kerogen samples after removal of bitumen generated during synthetic...

..., there are situations when it is not so clear, for example, when there is bitumen present. One definition of Bitumen is a general name for various solid and semi-solid hydrocarbons that are fusible and are soluble in carbon bisulfide (Bates R, Jackson J, 1984), and there are many different terms in practical use...

...) was 12,700 cp. After recombination, live-oil viscosity was reduced by factor of 3.4, to 3,700 cP. For bitumen and highly-viscous lab oil, experimental work shows that solution gas reduces viscosity and increases T 2 relaxation time (Yang, 2011), and that the type of solution gas strongly influences...
