Iran and Russian Federation have inked nine memorandums of understanding (MoUs) on expansion of economic ties.
Another one was signed between Federal Agency on Technical Regulation and Metrology of Russia (Rosstandart) and Iranian National Standards Organization.
The Iranian minister of petroleum, who was speaking to reporters on the sidelines of an MoU signing ceremony with Russia's Gazprom, said "so far, negotiations have been held with various Russian firms like Lukoil, Tatneft, Zarubezhneft and Gazprom on development of seven Iranian oil fields".
Commenting on the deal with Gazprom Neft, Zanganeh said this latest agreement brings the total number of Iranian fields under Russian companies' study to 7, with Russia accounting for the largest share of exploration deals compared to other countries.
"The sides highlighted Rosneft's interest in the mutually beneficial cooperation with Iranian oil companies in projects to develop big oil and gas fields in Iran's onshore and offshore areas with proven resources base, as well as in joining geological-prospecting blocks after studying their geological structure and resource potential", the document said.
Iranian President Hassan Rouhani has accepted Russian President Vladimir Putin's invitation to visit Moscow, Iranian Communications Minister Mahmoud Vaezi said Tuesday.
Iran's oil minister Bijan Namdar Zanganeh and Russia's energy minister Alexander Novak were present at the signing of the deal, in a sign that the two countries are further strengthening their energy ties at the highest level. The money is expected to spur trade from the current $2 billion to a target of $10 billion.
