Reservoir Rock, Seal, and 3 Dimensional Closure are three important features of what?

• A. Fault
• B. Seal
• C. Traps
• D. Reservoir

Answer: (C)

In petroleum geology, a trap is formed when there’s a reservoir rock with enough porosity and permeability to store hydrocarbons, an impermeable seal that prevents their migration, and a three‑dimensional closure that blocks movement in all directions. This combination creates a pocket where oil and gas can accumulate. Without the reservoir rock, there’s nothing to store the hydrocarbons; without a seal, they would seep away; without a closed 3D geometry, they wouldn’t be held in place. While faults and other structures can help create or enhance traps, the three elements together define the trapping mechanism that holds hydrocarbons.
