where is this gas produced?

The gas in question, natural gas, is produced deep underground in rock formations. It is formed over millions of years by the decomposition of plants and animals subjected to intense heat and pressure from the Earth. This natural gas is extracted by drilling wells into these underground rock reservoirs or shale formations. There are two main methods of extraction: conventional drilling into rock formations that trap the gas and hydraulic fracturing (fracking) which involves injecting fluid at high pressure into shale rock to release gas. Natural gas reservoirs can be located both onshore and offshore. The United States, Russia, Iran, China, and Canada are some of the world's top producers of natural gas. Natural gas can also be processed and liquefied (LNG) for easier transport and use. Therefore, natural gas is produced primarily from deep underground geological formations composed of rock and organic materials subjected to heat and pressure over geological time.
