maakaasuesiintymät
Maakaasuesiintymät refers to underground deposits of natural gas. Natural gas is a fossil fuel primarily composed of methane, but it can also contain varying amounts of other hydrocarbons like ethane, propane, and butane, along with non-hydrocarbon gases such as nitrogen, helium, and carbon dioxide. These deposits are typically found in porous and permeable rock formations, such as sandstone or limestone, which act as reservoirs. Above these reservoirs, impermeable rock layers, known as caprocks, prevent the gas from escaping.
The formation of maakaasuesiintymät is a geological process that takes millions of years. It begins with the
Exploration for maakaasuesiintymät involves geological and geophysical surveys to identify potential reservoir structures. Once a promising
