Kuwait has reportedly summoned the Iranian charge d’affaires to protest against a bid by Iran to develop unilaterally the disputed offshore Durra gas field, according to Gulf News.

The official Kuwait News Agency (Kuna) has not made an explicit announcement, however, saying instead that Foreign Ministry Undersecretary Khaled Suleiman Al Jarrallah on Sunday met Iranian Embassy’s Charge d’Affaires Hassan Zarinkar.

Apart from discussing bilateral ties the “two officials also tackled the latest regional and international developments,” the official news agency said.

Iran has repeatedly warned it would launch full-scale unilateral development of the disputed offshore gas field in the Gulf if Kuwait did not respond to its offer of joint development.

For its part Press TV said that just as there is a dispute between Iran and Kuwait over the joint field, there is also a standoff between Saudi Arabia and Kuwait which came to a head in 2013 when a joint project was shelved amid disagreement on how to share the produced gas.

According to the Iranian the shared field is estimated to hold a trillion cubic feet of gas and with 310 million barrels of oil.

The field is one among nearly 50 oil and gas projects worth $185 billion Iran plans to develop and will be introduced along with the country’s new contract model at the London conference planned for December.
