1. Structural traps: Structural traps are formed by the deformation of the Earth's crust, such as folding or faulting, which creates a barrier that traps hydrocarbons. Examples of structural traps include anticlines, fault traps, and salt domes.
2. Stratigraphic traps: Stratigraphic traps are formed by variations in the sedimentary rock layers that create barriers to the movement of hydrocarbons. Examples of stratigraphic traps include pinchouts, reefs, and unconformities.
3. Combination traps: Combination traps are formed by a combination of structural and stratigraphic elements. These traps are often more complex and can be more difficult to identify and exploit.
4. Diapiric traps: Diapiric traps are formed by the movement of salt or other mobile rock formations, which can create structural traps as well as stratigraphic traps.
5. Hydrodynamic traps: Hydrodynamic traps are formed by the movement of water within the reservoir, which can create barriers that trap hydrocarbons. These traps are often associated with faults or other structural features.
6. Paleogeomorphic traps: Paleogeomorphic traps are formed by changes in the landscape over time, such as erosion or deposition, which can create barriers that trap hydrocarbons.

Hydrocarbon Traps are geological structures or conditions that impede the upward migration of hydrocarbons (oil and gas) and result in their accumulation.
Types of Hydrocarbon Traps and their Formation Processes:
1. Structural Traps:
- Anticline Traps: Upward-folded rock layers where hydrocarbons accumulate in the crest of the anticline. Formed by tectonic forces, such as compression or folding.
- Syncline Traps: Downward-folded rock layers where hydrocarbons accumulate on the flanks of the syncline. Formed by tectonic forces or differential compaction.
- Fault Traps: Displacements in rock layers where hydrocarbons accumulate along the fault plane. Formed by tectonic movements or extensional forces.
- Salt Dome Traps: Upward-moving salt structures that trap hydrocarbons on their flanks. Formed by the deformation of salt layers due to pressure or tectonic forces.
2. Stratigraphic Traps:
- Pinch-Out Traps: Wedge-shaped rock layers that thin out and eventually disappear, trapping hydrocarbons in the porosity of the pinching-out layer. Formed by changes in sediment deposition or erosion.
- Unconformity Traps: Contacts between different rock layers where hydrocarbons accumulate in the truncated older rocks or porous overlying rocks. Formed by erosion or non-deposition during geological time gaps.
- Lens Traps: Lenticular-shaped bodies of porous or permeable rock surrounded by impermeable rock. Formed by sedimentation processes or dissolution cavities.
3. Combination Traps:
- Fault-Anticline Traps: Combinations of anticline traps and fault traps, where hydrocarbons accumulate in the crest of a folded layer and are sealed by a fault.
- Salt Dome-Anticline Traps: Combinations of salt dome traps and anticline traps, where hydrocarbons accumulate in the crest of an anticline formed on the flanks of a salt dome.
4. Other Traps:
- Hydrodynamic Traps: Buoyancy forces due to variations in fluid density trap hydrocarbons. Formed by groundwater flow or differential compaction.
- Stratigraphic-Structural Traps: Combinations of stratigraphic and structural features, such as the accumulation of hydrocarbons in a fold with a pinch-out trap.
