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 (29,000 m3) a day.
With injection of 3.6 billion cubic feet (100,000,000 m3) of gas per day (20 trillion cubic feet (570 km3) of gas in total) 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]
