PetroChina, China's largest oil and gas producer, had 20.5 billion barrels of oil and gas reserves in 2006.
The company has been adding new reserves at an average annual rate of 5 percent for the past three years, a faster pace than Exxon, Royal Dutch Shell Plc and BP Plc, the world's largest oil companies by sales.
The share sale, the world's biggest this year, surpassed the 66.6 billion yuan raised by China Shenhua Energy Co. in September.
PetroChina raised 66.8 billion yuan selling 4 billion shares last week as investors applied for more than 3.3 trillion yuan of stock, almost 50 times the amount PetroChina sold.
