The way molecules are organized in the hydrocarbon is a result of the original composition of the algae, plants, or plankton from millions of years ago. The amount of heat and pressure the plants were exposed to also contributes to variations that are found in hydrocarbons and crude oil.
On March 3, 1938, an American-owned oil well in Dhahran, Saudi Arabia, drilled into what would soon be identified as the largest source of petroleum in the world. The discovery radically changed the physical, human, and political geography of Saudi Arabia, the Middle East, and the world.
On March 3, 1938, oil was discovered in Dammam, Saudi Arabia. This discovery changed Saudi Arabia and the world. Most of the developed world depends on oil for industry and transportation. Saudi Arabia sells more oil, to more countries, than any other nation in the world.
Whale oil and baleen (sometimes called whalebone, although it’s not bone at all) were valuable commodities. Whale oil comes from the blubber of right and bowhead whales, and the head cavity of sperm whales. It was used primarily for oil lamps. Corsets and hoop skirts were constructed from whalebone.
Like other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago. There are several different theories to explain how fossil fuels are formed.
Oil is originally found as a solid material between layers of sedimentary rock, like shale. This material is heated in order to produce the thick oil that can be used to make gasoline. Natural gas is usually found in pockets above oil deposits.
How were they formed? Learn how human use of non-renewable energy sources, such as coal, oil, and natural gas, affect climate change.
The van Krevelen Diagram is a method of classifying oil shales based on their depositional history. The diagram divides oil shales according to where they were deposited: in lakes (lacustrine), in the ocean (marine), or on land (terrestrial).
Peat is the "forgotten fossil fuel." While oil, coal, and natural gas are exported around the world, few outside northern Europe are aware of this energy source. In certain circumstances, peat can be an early stage in coal formation. Most of the time, however, peat is a unique material. Peat forms in bogs.
Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the planet. In the fracking process, cracks in and below Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure.
