“Energy” is the foundation of all kinds of life and economic activities in modern society; from daily electricity consumption to industrial production and military strategy, energy is indispensable. Among them, “oil” is the most important energy fuel nowadays.

Natural gas and oil commonly co-exist in underground deposits that were once active bodies of water. After millions of years of drying, these dry beds leave behind fossils, plants, and other debris that have been covered and compressed by soil for years, and combined with the Earth’s heat, they are transformed into oil or natural gas, which is stored in the surrounding rock layers.

The main uses of natural gas and oil are to generate electricity, heat, power vehicles or process various products.
