EghtesadOnline: Iran has an estimated $400 billion worth of physical assets in the petroleum industry, but low efficiency and high rates of incidents in the industry show the country's oil and gas infrastructures require a major overhaul, according to an Oil Ministry official.

EghtesadOnline: Almost $65 million (2.5 trillion rials) has been invested in infrastructure projects in the southern oil and gas regions, Ali Kardor, the chief executive officer of National Iranian Oil Company said.
