The History of Oil: A Powerful Force Shaping the Modern World

Pros and Cons of Oil Energy

Oil energy has been a critical driving force in the development of human civilization. Since its discovery in 600 B.C. by the Chinese, oil has gone on to play a pivotal role in global politics, economics, and the environment. This article will take a journey through the history of oil and its lasting impact on the world.

The 18th century marked a significant turning point for energy sources, with the invention of the steam engine leading to a shift from wood to fossil fuel in the form of coal. However, it wasn’t until Colonel Drake’s discovery of oil in Pennsylvania in 1859 and the Spindletop discovery in Texas in 1901 that the foundation for the modern oil industry was laid. These discoveries eventually led to petroleum becoming the preferred energy source in the 20th century, driven by the invention of the electric light bulb and the automobile.

The first oil corporation, Pennsylvania Rock Oil Company, was founded to exploit oil found near Titusville, Pennsylvania. Soon after, John D. Rockefeller established Standard Oil Company, which controlled 90% of America’s refining capacity by 1879 and later became ExxonMobil. Royal Dutch Shell and British Petroleum (BP) are considered the original “supermajors,” along with ExxonMobil.

The Seven Sisters cartel, comprised of Exxon, Royal Dutch/Shell, BP, Mobil, Texaco, Gulf, and Chevron, controlled the global oil and gas business for much of the 20th century. However, a significant shift occurred with the founding of the Organization of the Petroleum Exporting Countries (OPEC) in 1960. OPEC was established to negotiate with Integrated Oil Companies (IOCs) on matters of oil production, prices, and concession rights. Today, OPEC controls 81% of the world’s oil reserves, with Saudi Arabia, Iran, and Venezuela holding the largest shares.

National Oil Companies (NOCs) now control 73% of the world’s oil and gas production, marking a notable shift from the dominance of IOCs in the past. Advances in unconventional oil and gas production, such as hydraulic fracturing (fracking), horizontal drilling, and deepwater production, have significantly altered the global energy landscape in the last 15 years.

Fracking, in particular, has led to a boom in North American oil and gas production, drastically reducing domestic natural gas prices. These low prices have resulted in a switch from coal to gas-fired power plants, increased use of natural gas in transportation, and challenges to the economics of renewable energy. However, the environmental impact of fracking remains a topic of debate, with concerns about water usage, potential contamination of groundwater, and treatment of used frack water.

The US is currently experiencing its highest oil and gas production levels in 20 years, with significant implications for energy independence and political regimes. Venezuela holds the largest oil reserves in the world, estimated at 300 billion barrels, followed by Saudi Arabia and Canada.

Throughout history, oil has played a critical role in shaping the modern world. The future of the oil industry is likely to be influenced by technological advancements, geopolitical dynamics, and the ongoing debate over environmental impact and sustainable energy sources. As our understanding of the effects of climate change, carbon dioxide emissions, and greenhouse gases grows, so too does the push for increased energy efficiency and the development of alternative, sustainable sources of energy. The history of oil is a fascinating and complex story, and its future remains uncertain as the world continues to grapple with the challenges of balancing economic growth, energy needs, and environmental concerns.
