Description

Oil and Gas are naturally occurring hydrocarbon resources that serve as the backbone of the global energy industry. They are formed from the decomposition of ancient marine organisms buried under layers of sedimentary rock over millions of years, subjected to intense heat and pressure. These fossil fuels are extracted through drilling and exploration activities and refined into various useful products.

1 . Crude Oil

Crude oil is an unrefined petroleum product composed of complex mixtures of hydrocarbons. It varies in color and viscosity, ranging from light and sweet to heavy and sour, depending on its sulfur content and density. After extraction, crude oil undergoes refining to produce fuels and derivatives such as:

Gasoline (Petrol)

Diesel fuel

Kerosene / Jet fuel

Liquefied Petroleum Gas (LPG)

Lubricants and asphalt

Crude oil is a vital feedstock for petrochemical industries, producing plastics, fertilizers, synthetic fibers, and other essential materials.

 

2. Natural Gas

Natural gas is a clean-burning fossil fuel primarily composed of methane (CH₄), often found in association with crude oil or as a separate natural gas field. It is extracted, processed, and supplied for domestic, industrial, and commercial use.
Natural gas is commonly used for:

Electricity generation

Industrial heating and production

Residential cooking and heating

Production of fertilizers (ammonia and urea)

Feedstock for petrochemicals and hydrogen

Processed forms include Liquefied Natural Gas (LNG) and Compressed Natural Gas (CNG), which facilitate storage and transportation.

 

3. Liquefied Petroleum Gas (LPG)

LPG consists mainly of propane and butane, produced during crude oil refining and natural gas processing. It is stored as a liquid under moderate pressure and is used extensively as:

extensively as:

Household cooking gas

Fuel for heating and vehicles

Raw material for petrochemical industries.

 

4. Significance

The oil and gas sector is a key driver of global economic growth, powering industries, transportation, and modern infrastructure. It also contributes significantly to export revenues and foreign exchange earnings in many producing countries

 

5. Environmental and Sustainability Considerations

The oil and gas industry is increasingly adopting cleaner technologies, carbon capture, and renewable energy integration to minimize environmental impact and support the transition toward sustainable energy.
