The age of the rock does not necessarily coincide with the time of oil accumulation.

3 RESERVOIR ROCKS A reservoir rock is a subsurface volume of rock that has sufficient porosity and permeability to permit the migration and accumulation of. 41 Structural trapa(????) -- Anticline.

. Nayef Alyafei has based this work on his own popular lecture courses and his extensive research in multiphase flow in porous media.

Minerals: • - specific chemical composition • - usually (but not necessarily) crystalline • - inorganic • - solid •. Cap rock.

The rock structure surrounding the reservoir has to be looked at carefully: Synclinally folded rocks dip towards the reservoir, reducing possible leakage but increasing their liability to slip into the reservoir.
