IRAN'S GAS AND OIL STORES , OIL COMPANIES AND CARLOS PASCUAL

Representatives of the American Petroleum Institute, BP and ConocoPhillips Co. told The Hill they did not send anyone on the trip, and the two oil producers said they are not currently negotiating with Iran on oil projects.

France’s Total, Norway’s Statoil and Italy’s ENI did not return requests for comment on the trip nor on their interests with Iran.

Iran’s oil ministry said that companies from Germany, Italy and the Netherlands have also expressed interest in oil and natural gas projects.

Iran likely had a small amount of foreign oil investment, mostly in the form of joint ventures with the government, before the United States and the European Union implemented sanctions in 2012 that prohibited many Western companies from working there.

Carlos Pascual, a senior vice president at energy consulting firm IHS who left the State Department last year as its top energy envoy, said contract terms are probably the top agenda item for Western oil companies negotiating with Iran. http://thehill.com/policy/energy-environment/241290-iran-courting-us-oil-interests-in-secret-talks

Iran has the fourth largest oil reserves and the largest natural gas reserves in the world.[1][2]
