Oil & Gas Upstream - How did the industry start?

Scientific concepts, discoveries, and natural phenomena

• Formation and age of crude oil: Crude oil is described as “hundreds of millions of years” old, formed over geological timescales.
• Natural oil seepage: For most of history, crude oil was mainly seen as messy natural seepage from the ground in specific locations.
• Hydrocarbons as a subsurface resource: The video frames crude oil and natural gas as subsurface hydrocarbons that can be identified and extracted.

Key technological / methodological ideas (industry startup & evolution)

Commercial scale transformation (1859)

• Concept: Turning crude oil into kerosene for lighting (a substitute for whale oil).

Drilling as the enabler of extraction

• Early method: Use of a steam-powered drill and steel pipes to drill and line wells.
• Discovery outcome: Drake “struck oil” in Titusville, Pennsylvania, marking the start of commercial extraction racing.

Early exploration approaches (high uncertainty)

• Reliance on indirect clues such as:
  • Oil seeps
  • Geological formations
  • Witching/divining with a “magic oil detecting stick” (divining rod)

Modern exploration (reduced speculation)

• Geological knowledge plus seismic surveying technology allows operators to locate hydrocarbons more reliably.

Modern extraction challenges (deeper reservoirs)

• Trend: “Easy to reach” oil is depleted; deposits increasingly become hard to reach.
• Depth progression:
  • Early wells: as shallow as ~10 m
  • Today: typically ~1 to 3 km, sometimes >10 km
• Implication: requires more sophisticated drilling and well technologies, supporting the growth of a large global oil and gas upstream industry.

Industry framing concepts (upstream value chain)

• The upstream segment is defined as three core steps:

  1. Exploration: assess where crude oil and natural gas deposits are.
  2. Development: prepare wells and infrastructure.
  3. Production: extract hydrocarbons and prepare them for transport.

• Types of upstream operators:

  • International oil companies (IOCs): Shell, Chevron, BP, Exxon Mobil
  • National oil companies (NOCs): Saudi Aramco, Petrobras, India Oil
