How are oil and gas trapped in rock strata? What are these traps called? What will be an ideal response?


Rock strata that can trap oil and gas are known as stratigraphic traps. A reservoir rock has an overlying
cap rock, and it is the difference between the rock types that traps the hydrocarbons. Structural traps
result when rocks are deformed by folding, fracturing, or both. The hydrocarbons migrate to the tops
of these structures. These require only a good reservoir rock to hold the oil and gas.
