The key components of natural gas include hydrocarbons, which are molecules compose of hydrogen and carbon atoms. The primary component of natural gas is methane (CH₄), it can contain hydrocarbons and impurity. Here are the key component:


Propane is heavier hydrocarbon present in natural gas. It has three carbon atoms and eight hydrogen atoms. Propane is commonly use as a fuel for heating, cooking, and transportation.


Methane is the primary component of natural gas, typically making up a significant portion of its composition. It is a simple hydrocarbon with one carbon atom and four hydrogen atoms.


Ethane is a heavier hydrocarbon available in natural gas. It consists of two carbon atoms and six hydrogen atoms. Ethane is often separate from natural gas and use as a feedstock for the petrochemical industry.


Butane is a heavier hydrocarbon with four carbon atoms and ten hydrogen atoms. Like propane, butane is use as a fuel for heating and cooking and is employ as a fuel in some vehicles.

Shale Gas  

Shale gas is a type of natural gas traps shale rock formations deep beneath the Earth’s surface. It is extract through a process know as hydraulic fracturing or fracking.

CNG (Compressed Natural Gas)  

CNG stands for Compressed Natural Gas. It is a type of natural gas that has been compress to reduce its volume for storage and transportation. CNG primari contains methane (CH₄) and is use as a fuel for various applications.

LPG (Liquified Petroleum Gas)  

LPG stands for Liquefied Petroleum Gas. It is a flammable hydrocarbon gas use as fuel in heating appliances, cooking equipment, vehicles, and various industry applications.

LPG is commonly compose of propane (C₃H₈) and butane (C₄H₁₀), and its physical state can change from gas to liquid under moderate pressure.

Methane Hydrate  

Methane hydrate, known as methane clathrate or methane ice, is a crystalline solid compound consist of methane molecules trapped within a lattice of water molecule.

It forms under specific conditions of low temperature and high pressure, typically in deep-sea sediments and permafrost regions. Methane hydrate is popularly refer to as “fire ice,” it can burn if ignite and appears to be ice-like.

Natural Gas Condensate  

Natural gas condensate, simply refer to as condensate, is a liquid hydrocarbon mixture that forms it is subject to changes in temperature and pressure. It is typically visible in association with natural gas reservoir.

Infrastructure Development  

It infrastructure, including pipelines and storage facilities, is well-establish in many regions. This infrastructure supports the reliable transportation and distribution of natural gas to end-users.

Origin Of Natural Gas

Origin Of Natural Gas

Organic Formation Process  

“Natural gas is more ubiquitous than oil. It is derived from both land plants and aquatic organic matter and is generated above, throughout, and below the oil window. Thus, all source rocks have the potential for gas generation.”

The Biological Stage  

“During the immature, or biological, stage of petroleum formation, biogenic methane (often called marsh gas) is produced as a result of the decomposition of organic material by the action of anaerobic microbes.”

The Thermal Stage   

“In the postmature stage, below about 5,000 meters (16,000 feet), oil is no longer stable, and the main hydrocarbon product is thermal methane gas. The thermal gas is the product of the cracking of the existing liquid hydrocarbons.”

Inorganic Formation  

“Inorganic processes may have produced some methane. The original source of Earth’s carbon was the cosmic debris from which the planet formed. If meteorites are representative of this debris, the carbon could have been supplied in comparatively high concentrations as hydrocarbons, such as are found in the carbonaceous chondrite type of meteorites.”

The Geologic Environment   

“Like oil, natural gas migrates and accumulates in traps. Oil accumulations contain more recoverable energy than gas accumulations of similar size, even though the recovery of gas is a more efficient process than the recovery of oil.”

Conventional Gas Reservoirs  

“Gas reservoirs differ greatly, with different physical variations affecting reservoir performance and recovery. In a natural gas (single-phase) reservoir it should be possible to recover nearly all of the in-place gas by dropping the pressure sufficiently.”

Unconventional Gas Reservoirs  

“Substantial amounts of gas have accumulated in geologic environments that differ from conventional petroleum traps. This gas is termed unconventional gas and occurs in “tight” (i.e., relatively impermeable) sandstones, in joints and fractures or absorbed into the matrix of shales, and in coal seams.”

Tight Gas  

“Tight gas occurs in either blanket or lenticular sandstones that have an effective permeability of less than one millidarcy (or 0.001 darcy, which is the standard unit of permeability of a substance to fluid flow).”

Shale Gas  

“Shale gas was generated from organic mud deposited at the bottom of ancient bodies of water. Subsequent sedimentation and the resultant heat and pressure transformed the mud into shale and also produced natural gas from the organic matter contained in it.”

Coal-Based Methane   

“Considerable quantities of methane are trapped within coal seams. Although much of the gas that formed during the initial coalification process is lost to the atmosphere, a significant portion remains as free gas in the joints and fractures of the coal seam; in addition, large quantities of gas are adsorbed on the internal surfaces of the micropores within the coal itself.”

Geopressured Fluids And Methane Hydrate  

“Geopressured reservoirs exist throughout the world in deep, geologically young sedimentary basins in which the formation fluids (which usually occur in the form of a brine) bear a part of the overburden load. The fluid pressures can become quite high, sometimes almost double the normal hydrostatic gradient.”
