How are hydrocarbons extracted from under the ground? | Explained

Syllabus: GS I, Subject: Geography, Topic: Resources – World and India, Issue: Petroleum and Natural Gas

Context: Two Industrial Revolutions were the result mainly of people finding a way to extract hydrocarbons and using them


  • Hydrocarbons like natural gas, coal, crude oil, and petroleum are found in subterranean rock formations.
  • Reservoirs form when a resistant rock overlies a less resistant one, trapping hydrocarbons below.
  • Petroleum geologists assess rock porosity and permeability to determine hydrocarbon potential.
  • Kerogen, organic matter, is the primary source of hydrocarbons in rocks.
  • Kerogen can originate from lacustrine, marine, or terrestrial ecosystems.
  • Source rocks are sought out by geologists for their ability to yield hydrocarbons.
  • Exploration involves modelling, observational data, and drilling smaller wells.
