What is Petroleum and How is it Formed?
Petroleum is a complex mixture of hydrocarbons, which are organic compounds that contain only carbon and hydrogen atoms. Hydrocarbons can have different structures, sizes, and properties, depending on how they are arranged and bonded. Some common examples of hydrocarbons are methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), benzene (C6H6), and octane (C8H18).
The Origin of Petroleum
Petroleum is formed from the remains of ancient plants and animals that lived millions of years ago. These organisms died and sank to the bottom of oceans and lakes, where they were buried by layers of sediment and rock. Over time, the high pressure and temperature in the earth's crust transformed the organic matter into petroleum. This process is called diagenesis.
The Composition of Petroleum
Petroleum is not a uniform substance. It varies in composition depending on where it is found and how it was formed. However, most petroleum consists mainly of four types of hydrocarbons: paraffins, naphthenes, aromatics, and asphaltenes. Paraffins are straight-chain or branched-chain hydrocarbons that have high volatility and low density. Naphthenes are cyclic or ring-shaped hydrocarbons that have medium volatility and density. Aromatics are ring-shaped hydrocarbons that have one or more benzene rings attached to them. They have low volatility and high density. Asphaltenes are complex molecules that contain nitrogen, sulfur, oxygen, and metals. They have very low volatility and very high density.
The Classification of Petroleum
Petroleum can be classified according to its physical and chemical properties, such as density, viscosity, sulfur content, API gravity, etc. One common way to classify petroleum is by using the American Petroleum Institute (API) gravity scale. This scale measures how heavy or light a petroleum liquid is compared to water. Water has an API gravity of 10 degrees. Higher API gravity means lighter petroleum; lower API gravity means heavier petroleum. For example, gasoline has an API gravity of about 60 degrees; diesel has an API gravity of about 40 degrees; crude oil has an API gravity of about 30 degrees.
How is Petroleum Extracted and Processed?
Petroleum is found in underground reservoirs that are trapped by impermeable rocks or structures. To extract petroleum from these reservoirs, various technologies and methods are used.
The Exploration of Petroleum
The exploration of petroleum involves finding and locating potential petroleum reservoirs. This can be done by using geological, geophysical, geochemical, and other techniques. For example, geologists can study the rock formations and structures of an area to identify possible petroleum sources. Geophysicists can use seismic waves, gravity, magnetism, and other methods to detect anomalies or variations in the subsurface. Geochemists can analyze the soil, water, gas, and rock samples to determine the presence and quality of petroleum.
The Drilling of Petroleum
The drilling of petroleum involves creating a hole or a well in the earth's surface to reach the petroleum reservoir. This can be done by using rotary drills, percussion drills, directional drills, or other tools. The drilling process can be divided into several stages, such as spudding, drilling, casing, cementing, logging, testing, completing, and producing. For example, spudding is the initial stage of drilling where a small hole is made to start the well. Drilling is the main stage of drilling where a larger hole is made to reach the target depth. Casing is the stage of drilling where steel pipes are inserted into the well to prevent collapse and leakage. Cementing is the stage of drilling where cement is pumped into the well to seal the gaps between the casing and the rock. Logging is the stage of drilling where various measurements and data are collected from the well to evaluate its condition and potential. Testing is the stage of drilling where the well is tested for its flow rate, pressure, temperature, and other parameters. Completing is the stage of drilling where the well is prepared for production by installing valves, pumps, tubing, etc. Producing is the stage of drilling where the well is ready to produce petroleum.
The Production of Petroleum
The production of petroleum involves extracting petroleum from the well and transporting it to the surface. This can be done by using natural pressure, artificial lift, enhanced recovery, or other methods. For example, natural pressure is the force that pushes petroleum out of the reservoir due to its own weight or gas expansion. Artificial lift is the use of pumps or other devices to increase the pressure or flow of petroleum in the well. Enhanced recovery is the use of chemicals, steam, gas injection, or other techniques to improve the recovery or extraction of petroleum from the reservoir.
The Refining of Petroleum
The refining of petroleum involves processing petroleum into various products and by-products. This can be done by using distillation, cracking, reforming, alkylation, polymerization, or other methods. For example, distillation is the process of separating petroleum into different fractions based on their boiling points. Cracking is the process of breaking down large hydrocarbon molecules into smaller ones by using heat or catalysts. Reforming is the process of changing the structure or composition of hydrocarbon molecules by using heat or catalysts. Alkylation is the process of combining small hydrocarbon molecules into larger ones by using acids or bases. Polymerization is the process of linking small hydrocarbon molecules into long chains by using heat or catalysts.
How is Petroleum Used and Consumed?

Climate change can have significant impacts on ecosystems, biodiversity, food security, water resources, health, economy, and society.
How is Petroleum Traded and Regulated?
Petroleum is a valuable and strategic commodity that is traded and regulated by various actors and institutions. It affects the economy, politics, and security of many countries and regions.
The Price of Petroleum
The price of petroleum is determined by the interaction of supply and demand in the global market. Supply is the amount of petroleum that is available for sale. Demand is the amount of petroleum that is wanted for purchase. The price of petroleum can fluctuate depending on various factors that affect supply and demand, such as production levels, consumption patterns, reserves, inventories, spare capacity, geopolitics, weather, technology, speculation, etc. For example, if the supply of petroleum decreases due to a disruption in a major producing country or a decline in reserves, the price of petroleum will increase. If the demand for petroleum increases due to a growth in population or economy or a shift in preferences, the price of petroleum will increase.
The Markets of Petroleum
The markets of petroleum are the places where petroleum is bought and sold. There are two types of markets: physical markets and financial markets. Physical markets are where actual petroleum products are exchanged for money. Financial markets are where contracts or derivatives based on petroleum products are traded for money. Physical markets can be divided into spot markets and contract markets. Spot markets are where petroleum products are traded for immediate delivery. Contract markets are where petroleum products are traded for future delivery. Financial markets can be divided into futures markets and options markets. Futures markets are where contracts that oblige the buyer to purchase and the seller to deliver a specific quantity and quality of petroleum product at a specific date and price are traded. Options markets are where contracts that give the buyer the right but not the obligation to purchase or sell a specific quantity and quality of petroleum product at a specific date and price are traded.
The Policies of Petroleum
, consumption, and trade of petroleum. The policies of petroleum can be made by various actors and institutions, such as governments, corporations, organizations, and individuals. The policies of petroleum can have different objectives and impacts, such as ensuring energy security, promoting economic development, protecting the environment, maintaining social welfare, etc. For example, governments can impose taxes, subsidies, tariffs, quotas, standards, or bans on petroleum activities to influence the price, supply, demand, or quality of petroleum. Corporations can invest in research and development, exploration and production, refining and marketing, or mergers and acquisitions to increase their profits, market share, or competitiveness.
