Substantial Growth in Gas Swap 

The volume of natural gas swapped between Iran and Turkmenistan soared by 385% in 2022 compared to the previous year, the managing director of the National Iranian Gas Company said.
“NIGC’s revenues via swap operations also grew by 530% during the period,” Majid Chegeni was also quoted as saying by ISNA.
In December 2021, Tehran signed a gas swap agreement with Ashgabat and Baku, based on which NIGC delivers 2 billion cubic meters of Turkmen gas to Azerbaijan annually, he added.
Under the swap deal, NIGC receives gas from Turkmenistan, located to the east of the Caspian Sea and delivers an equivalent volume to Azerbaijan on the western side of the sea at the Astara border.
