Efforts are underway to start producing gas from a platform of the phase, Ali Akbar Shabanpour was quoted as saying by the official website of the oil ministry.
He further emphasized that gas has already been pumped to the refinery of Phase 18 of the South Pars gas field.
The official went on to say that increasing gas production capacity in the phases 15 to 19 of the giant gas field is among the priorities of the Pars Oil and Gas Company.
The South Pars 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 is estimated that the Iranian section of the field contains 14 trillion cubic meters of gas and 18 billion barrels of condensates in place.
South Pars is part of a wider gas field that is shared with Qatar. The larger field covers an area of 9,700 square kilometers, 3,700 square kilometers of which are in Iran's territorial waters (South Pars) in the Persian Gulf. The remaining 6,000 square kilometers, referred to as the North Dome, are in Qatar's territorial waters.
