Alexei Miller and Gholamreza Ansari "discussed bilateral cooperation in the oil and gas sphere, in particular the South Pars deposit."
Iran has proven natural gas reserves of around 28 trillion cubic meters, the world's second largest reserves behind Russia. In 2005, gas production in the country totaled 86.6 bln cu m.
South Pars holds 60% of Iran's reserves, and 10% of known world reserves of natural gas. The deposit is a part of the North Dome deposit, the largest non-associated gas field in the world, situated in Qatar and Iran.
