Lithology density
The term lithology is used as a gross identification for a rock layer in the subsurface and uses familiar names such as: 1. Sandstone (or sand) 2. Limestone 3. Dolostone (or dolomite) 4. Claystone (or clay) 5. Chert 6. Coal 7. Shale (or mudrock) 8. Diatomite 9. Halite 10. Anhydrite 11. Gypsum 12. Tuff … Meer weergeven Obtaining a physical sample of the reservoir is the surest way to unambiguously determine lithology and rock type, but obtaining this physical sample is not always easy. Mud logs are the first … Meer weergeven If no direct rock sample is available in a given zone, log responses must be used alone to simultaneously determine lithology, … Meer weergeven Geologists are trained to describe rocks, based on: 1.
