− | Certain [[structural domains]] or specific portions of those domains provide the greatest opportunities for exploration success. Those areas are called '''prospective structural fairways'''. In a prospective structural fairway, the structural history, [[trap]] configuration, and major elements of the hydrocarbon system combine to present a likely scenario for an economic accumulation of hydrocarbons. | + | Certain [[structural domains]] or specific portions of those domains provide the greatest opportunities for exploration success.
