Aghajari Gas Injection Project is the world’s biggest Enhanced Oil Recovery (EOR) project to be inaugurated in Iran in late 2008.

The reservoir dimension of Aghajari ‎fields is 56×6 km with the original oil-‎in-place of 28 billion barrels (4.5×109 m3) and 10.2 billion ‎barrels of recoverable oil (based on ‎latest studies). The total quantities ‎extracted since the start of operations at ‎Aghajari till this date have been 8.8 bn ‎barrels.‎[1]

However, production has been on the ‎decline because of loss of pressure and ‎oil extraction, so that current output is ‎‎180,000 barrels a day.

With injection of 3.6 billion cubic feet (100,000,000 m3) of gas per day (20 trillion cubic feet of ‎gas in tolal) from the south pars field and ‎subsequent buildup of pressure, an ‎additional quantity of 1.2 billion barrels (190,000,000 m3) of oil ‎will be produced. It is also estimated ‎that daily crude oil output of the field ‎will increase to 300,000 barrels per day (48,000 m3/d).‎[1]

Project consists of three main parts;

  • Upstream:

Development of South Pars phases 6, 7 and 8.

  • Midstream:

The 504-km long, 56-inch pipeline for transfer of sour gas from the South Pars gas field phases 6,7 and 8 to be injected to Aghajari oilfield.

  • Downstream:

Installation of a gas-compression ‎station, drilling of 19 new wells, work ‎over of 3 existing wells for gas ‎injection, installing pipelines on 2 ‎existing gas injecting wells.[1]
