Natural gas

Natural gas is a vital component of Earth's energy mix, formed deep within the Earth over millions of years. It primarily consists of methane (CH4) along with small amounts of other hydrocarbons. Geologically, natural gas forms through the decomposition of organic matter under high pressure and temperature in sedimentary rocks like shale and sandstone. It often accumulates in porous reservoir rocks, capped by impermeable layers that trap it underground.

Extracting natural gas involves drilling wells into these reservoirs and using hydraulic fracturing (fracking) techniques to release it from tight rock formations. This process requires careful geological analysis to locate viable reserves and understand the underground structures that hold them. Geologists play a crucial role in mapping out these formations and assessing the environmental impacts of extraction, ensuring responsible and sustainable utilization of this valuable energy resource.
