underground reservoirs
Underground reservoirs are natural or man-made spaces beneath the Earth's surface that store liquids like water, oil, or natural gas. They form when these fluids accumulate in porous rock formations, such as sandstone or limestone, which can hold significant amounts of fluid within tiny interconnected pores. These reservoirs are accessed for extraction in industries like oil and gas or tapped for water supply through wells. They play a crucial role in resource management, providing stable storage that is protected from surface variations and contamination. Proper understanding and management of underground reservoirs are essential for sustainable resource use and environmental protection.
