Aghajari Gas Injection Project

Aghajari Gas Injection Project is the world’s biggest enhanced oil recovery) 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 Goilbbl 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.

However, production has been on the decline because of loss of pressure and oil extraction, so that current output is 180000 oilbbl a day.

With injection of 3.6 Gcuft of gas per day (20 e12cuft of gas in total) from the south pars field and subsequent buildup of pressure, an additional quantity of 1.2 Goilbbl of oil will be produced. It is also estimated that daily crude oil output of the field will increase to 300000 oilbbl/d.

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.
