It is related to sediment deposition or erosion and is bounded on one or more sides by zones of low permeability. 1 Structural Traps These traps form due to tectonic activities that deform rock layers. Requirements of Traps: Foul gases produced in the sewers, drains, waste-pipes may cause nuisance by entering in houses There are two main types of traps that can contain oil and gas deposits underground: structural traps and stratigraphic traps. [1] Levorsen’s scheme breaks Traps can be formed in many ways. Trap classifications is further complicated by combination or complex traps, which combine two or more trap styles (structural, stratigraphic or fluidic) depending on the contact depth. It occurs when the migration of reservoir fluid is halted as a result of a non-porous formation blocks the flow due to shift of formations. Structural Traps are classified into two with respect to the type of structure that produces them namely: structural traps and stratigraphic traps.
