Natural gas - Wikipedia
Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes. Traces of carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. [2] .
Natural gas origin, composition, and processing: A review
2016年8月1日 · Natural gas (NG) is a naturally gaseous hydrocarbon mixture that is formed under the earth’s surface. NG is considered to be the cleanest fossil fuel and is a safe source of energy when transported, stored and used.
Natural Gas – What is it, where is it, and how do we capture it?
Natural gas is found in rock formations deep below the surface of the Earth. Petroleum, or oil, is often found in the same areas. Humans have been using natural gas for cooking for hundreds of years. The first industrial extraction of natural gas was in New York State in 1825.

2023年10月19日 · While most conventional gas can be found just a few thousand meters deep, deep natural gas is located in deposits at least 4,500 meters (15,000 feet) below the surface of Earth. Drilling for deep natural gas is not always economically practical, although techniques to extract it have been developed and improved.
Natural Gas - an overview | ScienceDirect Topics
2019年12月26日 · Natural gas is produced from various resources at various depths beneath the earth's surface. Broadly, these resources can be categorized into conventional and unconventional reservoirs. Shale gas, tight gas, coal bed methane (CBM) are the major, commercially viable, unconventional natural gas resources.

Natural gas is the earth’s cleanest burning hydrocarbon. Its combustion does not produce ash residues, sulphur oxides, and only negligible nitrogen. This sets it apart from all the other fossil fuels. Natural gas forms organically over millions of years from decomposing plant and animal matter that is buried in sedimentary rock layers.

2023年5月31日 · Natural gas fields are located deep beneath the earth’s surface, and their formation and location are influenced by a variety of geological factors, including tectonic activity and the presence of traps in the rock formations.
Thermogenic methane—the natural gas formed deep beneath the Earth’s surface—can also escape into the atmosphere. Some of the gas is able to rise through permeable matter, such as porous rock, and eventually
