According to the National Iranian Oil Company (NIOC), the theme has been chosen to be in line with the Supreme Leader’s naming of the current calendar year (which began on March 21) as the year of Production Book, said Mohammad Naseri

The official stated that the showcase was one of the most important events among oil and gas industry exhibitions in the world.

Domestic oil industry capabilities in manufacturing of items and contracting firms have led to a mass of companies active in the fields in this year’s conference, he said, adding domestic companies were to occupy 35,766 square meters of land in the showcase which is over 7,000 square meters more than the previous edition of the fair.

Although intensification of the unilateral US sanctions had reduced the presence of foreign companies at the exhibition this year, many leading companies from such countries as Spain, Germany, Italy, Ukraine, China, Russia, the Netherlands, Azerbaijan, etc. are scheduled to run stands at the showcase, Naseri said.

The fair is slated to be held from May 1 to 4 at Tehran's permanent fairgrounds.
