Within the Kettleman Hills, oil is found in the large structural trap represented by the anticline.

The basin contains over 60 oil and gas fields mostly as structural traps within seventeen different formations.

The three basic forms of structural traps are the anticline trap, the fault trap and the salt dome trap.

All of these rock units are faulted and folded, forming structural traps, with oil trapped in anticlinal folds and along fault blocks.

Some of the oil-bearing zones, such as the 4th and 5th, are capped by the Barnard Fault, which provides an additional structural trap.

The actor exudes the aura of doing an act, giving in to the play's structural trap, as if it were a one-man show.

The oil itself probably originated in the underlying Monterey Formation, migrating upward to structural and stratigraphic traps over time.

The field is bounded on the northeast by a fault which serves as a structural trap since it is upgradient from the oil pools.

Oil produced from these source rocks has migrated upwards, forming reservoirs in both structural and stratigraphic traps.

They are more easily delineated and more prospective than their stratigraphic counterparts, with the majority of the world's petroleum reserves being found in structural traps.
