1. Increased demand: With the development of global economy and population growth, the demand for energy is increasing, especially for oil and natural gas. This has led to an increase in the market demand for natural gas by oil tycoons, which has led to an increase in its price.
2. Reduced supply: Oil and natural gas are limited resources, and their supply gradually decreases with the passage of time. At the same time, political instability and natural disasters in some areas may also lead to the interruption or reduction of supply. The reduction of supply will lead to the increase of natural gas prices of oil tycoons.
3. Investment and trading activities: The natural gas market of oil tycoons is a highly speculative market, and investors and traders make profits by buying and selling oil and natural gas futures contracts. When investors' demand for oil and natural gas increases, it will lead to price increases.
To sum up, the expansion of oil tycoon's natural gas is due to the comprehensive influence of many factors such as increasing demand, decreasing supply, investment and trading activities.
