The gas is being injected to the facilities
for consumption during winter and enhancing production of the country's oilfields.
Speaking to Shana, Saeid Tavakoli, the managing
director of National Iranian Transmission Company (NIGTC), said the gas is
sometimes used for injection in oilfields for boosting their output and after
all the recoverable oil is produced from the fields the gas will be kept there
for further consumption.
Natural gas, like many other commodities,
can be stored for an indefinite period of time in natural gas storage
facilities for later consumption.
The most important type of gas storage is
in underground reservoirs. There are three principal types — depleted gas
reservoirs, aquifer reservoirs and salt cavern reservoirs. Each of these types
has distinct physical and economic characteristics which govern the suitability
of a particular type of storage type for a given application.
In winter, NIGTC transfers 750 mcm/d of
gas in Iran and withdraws 8 mcm/d from Sarajeh during the cold snap.
The facility can store up to one billion
cubic meters of gas. This is while Shourijeh facility can store up to 2.5 bcm
in it. The plant received 2.5 mcm of gas in the first half of this calendar
Gas storage will continue until late November.
