EghtesadOnline: The world’s biggest gas field lies between Qatar and Iran, and the half-competitive, half-cooperative race to exploit it has taken a new turn. For both countries, this enormous resource is also a source of political power. Now, with the emirate at odds with Tehran’s foe, Saudi Arabia, its tacit cooperation with Iran is gaining, even as the two are set to compete more intensely in gas markets.

EghtesadOnline: Iran's major energy deal with French oil company Total, and Qatar's announcement that it will significantly hike gas production, could challenge America and its allies' energy dominance in the Persian Gulf.

EghtesadOnline: Saudi Arabia and key allies on Monday cut ties with Qatar, the world's top seller of liquefied natural gas (LNG), stoking concern over any supply disruptions to neighboring countries spilling over into global gas markets.

EghtesadOnline: Saudi Arabia’s isolation of Qatar has been brewing since 1995, and the dispute’s long past and likely lingering future are best explained by natural gas.

EghtesadOnline: Qatar, the world’s biggest seller of liquefied natural gas, can still access shipping routes to deliver oil and gas to buyers after Saudi Arabia and other neighboring states barred the emirate from exporting through their territorial waters.

EghtesadOnline: The most effective policy to challenge Qatar's efforts to boost production from the joint South Pars Gas Field in the Persian Gulf by 10% would be to accelerate development projects in the field by attracting new funding, a veteran economist says.

EghtesadOnline: Qatar Petroleum plans to start a new development in the offshore North Field, ending a 12-year ban on new projects that allowed the company to assess how its current rate of extraction affects the giant reservoir it shares with Iran.

EghtesadOnline: Iran will have launched several major phases of the huge South Pars gas field project in the Persian Gulf by the end of the current Iranian calendar year (March 20, 2017).
