Ahmad Valipour told reporters in the southwestern port city of Assalouyeh on Saturday that the sixth refinery has taken major and effective steps to meet the country's gas demand, particularly in the winter, reported Tasnim News Agency.
The steps "have led to an overall increase of 20 percent in gas production and injection into the national network compared to the first half of the current (Iranian) year (started March 21, 2018)", he noted.
The official further said that the refinery's total gas production has reached approximately nine million cubic meters per day.
According to Oil Minister Bijan Namdar Zanganeh, Iran is on pace to boost gas production to one billion cubic meters a day by March 2019, roughly the same time that all South Pars phases are planned to be up and running.
The gas field, whose development has been divided into 28 phases, is located in the Persian Gulf straddling the maritime border between Iran and Qatar.
It covers an area of 9,700 square kilometers, of which 3,700 square kilometers lie in Iranian territorial waters.
It is estimated that the Iranian sector of the field contains 14 trillion cubic meters of gas and 18 billion barrels of condensates in place.
