Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. The degree of wetting/wettebility is determined by a force balance between adhesive and cohesive forces. Wetting deals with three phases of matter: gas, liquid, and solid.

Wettability is the ability of any liquid to maintain it's contact with the solid. Depending on different properties of solid and liquid, the amount of wettability varies very significantly. The production of oil from sandstone and limestone reservoir rock is mainly dependent on the factor whether it's oil wet or water wet. Hydrocarbon production from water wet reservoirs are generally easier than production from oil wet reservoirs. Clean sandstone reservoirs tend to be water-wet, but many sandstone reservoir rocks are intermediate-wet. Carbonates reservoirs tend to be more oil-wet than clastics. So extracting hydrocarbons from oil wet carbonate reservoirs is comparatively difficult than water wet clastic reservoir. On the other hand, carbonate reservoirs have significant secondary porosity than clastic rocks, carbonate reservoir contains much higher hydrocarbon than clastic reservoir in general.
