n: I. a subsurface hydrocarbon trap that has the features of both a structural trap and a stratigraphic trap. 2. a combination of two or more structural traps or two or more stratigraphic traps.

a trap that has both structural and stratigraphic character.

n: a petroleum trap that occurs when the top of the reservoir bed is terminated by other beds or by a change of porosity or permeability within the reservoir itself. Compare structural trap.

a reservoir capable of holding fluids created by decreases in porosity, permeability or disappearance of the reservoir.

n: a petroleum trap that is formed because of deformation (such as folding or faulting) of the reservoir formation. Compare stratigraphic trap.

a combination of a formation structure feature such as a fault with a sealing mechanism that forms a place where oil accumulates or is “trapped”.

n: a body of permeable oil-bearing rock surrounded or overlain by an impermeable barrier that prevents oil from escaping. The types of traps are structural, stratigraphic, or a combination of these.

n: A configuration of rocks suitable for containing hydrocarbons and sealed by a relatively impermeable formation through which hydrocarbons will not migrate. Traps are described as structural traps (in deformed strata such as folds and faults) or stratigrap
