Answer:
Structural Trap , Stratigraphy trap , combination Trap .
Explanation:
Structural Trap -
It is a type of geological trap that is formed due to the tectonic , gravitational , changes in the structure of the subsurface and the compactional processes .
These changes leads to the formation of the petroleum reservoir by blocking the upward migration of the hydrocarbons.
They are one of the important traps since , it represents majority of the world's discovered petroleum resources .
The examples of the structural trap are -
the fault trap , anticline trap , and the salt dome trap .
Stratigraphy Trap -
The formation of Stratigraphic traps are due to the vertical and lateral variations in the texture , porosity , thickness and the lithology of the reservoir rock .
The examples of the Stratigraphy trap are -
An unconformity trap , a reef trap and a lens trap .
Combination Trap -
The trap having two or more trapping elements are called Combination traps. This type of trap is due to changes in lithology and tectonic process.
The examples of the Combination trap is -
salt dome.
