I want to know the answer to the following question:
Downstream operations produces what percent of Shell's profits worldwide?
All the background I'm provided with is that "The downstream business, which in some countries also included oil refining, generally included a retail petrol station network, lubricants manufacture and marketing, industrial fuel and lubricants sales and a host of other product/market sectors such as LPG and bitumen.". Is that enough to answer the question?
