Over the course of the last couple of centuries, major businesses all over the world have spent a great deal of time and money searching for and studying structural geologic features in order to find deposits of petroleum
How would these structures trap the substances these companies are interested in?
What will be an ideal response?
Answer: Oil companies are searching for or have searched for structural features such as domes, anticlines, and inclined faults. These features can act as petroleum traps. For example, petroleum will migrate along permeable rock layers in an anticline, making its way up the layer because it is less dense. Once the petroleum reaches the top of the fold, the overlying layer may act as an impermeable boundary, not allowing any further migration upward and trapping the product.
