Ammon – Oil shale is a type of sedimentary rock that contains combustible organic materials and is used to extract oil and natural gas. Here are some of the main characteristics of shales:
1. **Chemical composition:** Oil rocks contain high percentages of organic materials composed of carbon, such as oil, petroleum, and other hydrocarbons. These materials represent the main source of extraction.
2. **Permeability:** Oil rocks must be able to store oil and gas effectively, and this depends on the permeability and rock cohesion. Layered rocks composed of sand, gravel, and small stones are usually useful for containing oil and gas.
3. **Water content:** Oil shale can contain certain amounts of water, and this aspect must be taken into account during oil extraction operations.
4. **Geological composition:** Oil rocks are usually part of special underground geological formations, such as sand, stone, and sedimentary rock layers. Oil shales can be found in places that have seen natural organic deposition over the ages.
5. **Pressure and temperature:** The formation of oil and gas in oil rocks is affected by the pressure and heat present deep beneath the Earth’s surface.
6. **Exploration and extraction:** Extracting oil and gas from shale rocks requires special crushing and drilling operations that include prospecting, horizontal drilling, and geological imaging.
Shales represent an important source of oil and natural gas, and are found in various regions around the world. The uses of these energy materials represent a large part of the global economy and various industries.
