An oil trap is a geological formation that prevents the further migration of oil and gas, causing them to accumulate in a specific area. Oil traps can be formed by various geological structures such as faults, folds, and anticlines.
On the other hand, an oil reserve refers to the estimated amount of oil that can be economically extracted from a specific oil trap or oil field. Oil reserves are typically categorized as proven, probable, or possible reserves based on the level of certainty surrounding their extraction.
In summary, an oil trap is a geological formation that traps oil and gas in a specific area, while an oil reserve refers to the estimated amount of oil that can be extracted from that trapped area.

Oil Trap
- A geological structure that allows oil to accumulate underground.
- Typically consists of a porous rock layer (reservoir rock) overlain by an impermeable cap rock.
- Oil seeps into the trap from source rocks and becomes trapped due to the cap rock acting as a barrier to upward migration.
Features:
- May have multiple layers with varying porosity and permeability.
- Can range in size from small, localized traps to massive fields that span multiple square kilometers.
- Can be formed by various geological processes, such as faulting, folding, or the presence of salt domes.
Oil Reserve
- The amount of oil that has been discovered and can be economically extracted from an oil trap.
- Estimated by geologists based on the size, porosity, permeability, and other characteristics of the trap.
- May vary over time due to advancements in technology and changes in economic factors.
Features:
- Quantified in units of barrels or cubic meters.
- Represents only a portion of the potential oil present in the trap due to technical and economic constraints.
- Can be classified as proven reserves (with a high probability of extraction), probable reserves (with a moderate probability), and possible reserves (with a low probability).
Key Differences
- Definition: An oil trap is a geological structure that can hold oil, while an oil reserve is the estimated amount of recoverable oil from a trap.
- Purpose: Oil traps are natural formations, while oil reserves are calculated estimates based on the potential of a trap to yield oil.
- Discovery and Estimation: Oil traps are identified through geological exploration, while oil reserves are estimated through reservoir modeling and evaluation.
