With the news that the field in Afghanistan is now producing, it looks like CNPC has cemented its position as a key investor in Afghanistan. The 25-year contract the company has signed has it extracting 1.5m barrels per year, and it is currently looking to extract 1,950 per day.
Key for Afghanistan perhaps, but 1.5 million barrels a year isn't exactly key for China, which in 2011 imported roughly 5 million barrels a day. 1.5 million per year would barely be a half drop in a bucket.
