Oil: A Masterclass

Mark Nelson, managing director of Radiant Energy Group, joins us for a Masterclass on the slippery subject of oil. We zoom from ancient plankton to modern empires to see how a mysterious black liquid birthed from prehistoric seas now powers our civilization, touching on the complex chemistry, geology and history of oil.

Watch now on YouTube.

We talk about

  • The geology and chemistry of oil

  • Drilling technology and the fracking revolution

  • The infrastructure to transport oil

  • Strategic petroleum reserves

  • Oil market dynamics and boom-bust cycles

  • Oil’s environmental and geopolitical implications

  • The historical development of the oil industry

  • Numerous delightful tangents

Some takeaways

  • Oil is primarily formed from ancient marine organisms preserved in oxygen-poor environments over millions of years

  • Modern oil extraction involves sophisticated horizontal drilling and fracking techniques that have revolutionized production

  • The U.S. has become the world's largest oil producer largely due to technological advances in extracting oil from shale formations

  • Oil markets are characterized by complex boom-bust cycles influenced by both geology and geopolitics

  • Current proven oil reserves roughly equal the total amount humans have used historically (about 1.5 trillion barrels each)

"You were able to maintain an empire better with your powerful oil-burning ships, but you had to make sure your empire then included oil." – Mark Nelson

Deeper Dive

The formation of oil begins with microscopic marine organisms called plankton that die and settle in oxygen-poor environments. These organisms get buried under layers of sediment where heat and pressure transform them into kerogen, the precursor to oil. This process occurs primarily in shallow seas with specific geological conditions that prevent the organic matter from decomposing.

Modern oil extraction has evolved dramatically from early wells that were just a few dozen meters deep. Today's wells can extend multiple kilometers underground and often include horizontal sections that allow access to previously unrecoverable deposits. The development of hydraulic fracturing (fracking) has enabled the extraction of oil from tight shale formations by creating artificial fractures that allow oil to flow more freely.

The refining process separates crude oil into various products based on molecular weight. Approximately half of each barrel becomes gasoline, while about 20% becomes diesel fuel. The remaining portions are used for everything from jet fuel to plastics and pharmaceuticals. This versatility has made oil particularly valuable for modern industrial civilization.

The global oil market consumes approximately 100 million barrels per day, with the United States producing about 13 million barrels daily. The industry maintains strategic reserves and complex infrastructure including pipelines, tankers, and storage facilities to manage supply fluctuations. Modern ultra-large crude carriers can transport up to 2 million barrels of oil in a single voyage.

The economics of oil production are characterized by significant upfront investments and the need to maintain steady production rates to preserve reservoir integrity. This creates interesting market dynamics where producers may continue pumping even when prices fall below profitable levels, as demonstrated during the COVID-19 pandemic when oil prices briefly went negative.
