Oil and Gas Potential in Sandstone Formation

Why are oil and gas able to rise through sandstone?

A. Sandstone is old.

B. Sandstone is trapped.

C. Sandstone is heavy.

D. Sandstone is porous.

Answer:

The correct answer is D. Sandstone is porous.

Sandstone is a type of sedimentary rock that is composed of sand-sized mineral particles. It is known for its porous nature, which allows fluids such as oil and gas to flow through it. When oil and gas are trapped beneath the surface of the Earth, they can migrate through porous sandstone formations towards the surface.

This porous characteristic of sandstone makes it an ideal reservoir for hydrocarbons. As oil and gas move through the interconnected pore spaces within the sandstone, they can accumulate in larger quantities, forming an economically viable resource.

Exploration and production companies often target sandstone formations for drilling operations due to their potential to contain significant amounts of oil and gas. Understanding the properties of sandstone, including its porosity, is crucial in identifying and extracting these valuable resources.
