Host Kai Ryssdal, who's been talking to experts about oil this week, speaks today with oil analyst Ruchir Kadakia about OPEC's standing in the oil world these days.

You may not hear a lot about it, but Russia is second only to Saudi Arabia in oil production. And, as Russia analyst Nicholas Redman tells Kai Ryssdal, it may have a greater potential for growth.

In his continuing series of interviews on oil prices, host Kai Ryssdal talks with Fareed Mohamedi of PFC Energy about how Nigeria's production of about 2 million barrels of crude a day affects what we pay at the gas pump.

Taking another look at the oil industry's affect on price hikes, host Kai Ryssdal discusses the problems President Hugo Chavez has caused for Venezuela's once impressive oil companies.

This week host Kai Ryssdal explores what's up with the oil market other than prices. Today he talks to George Joffe at Cambridge University about the world's fourth largest oil exporter — Iran.
