Current states of world petroleum resource and its future trends

The current states of world oil and gas resources, the relationship between world oil and gas supply and demand, and the trend of world oil and gas price change and economic development have been detailed and analyzed in this paper. We noticed that in a limited time span (e.g. 100 years), world oil and gas discovery and production would go up other than follow a bell shape, and excess oil and gas supply and low oil and gas prices would maintain a long time (e.g. 10 years). The author recommends that both the government and company should reduce upstream investment, limit funding should focus on giant basin and prolific hydrocarbon depressions guiding by low cost and high efficiency policy, and more effort should shift to renewable energy development. Low-carbon and healthy environment should be the common goal of mankind.
